You Current Options - Token Current Sense
As the world becomes more and more technology-driven, the uses for current sensing resistors will
continue to increase. The need for even lower resistance value ranges is already becoming evident,
as is the need for these resistors to handle more power. The industry-wide trend is the emergence of
smaller and smaller products.
Token Electronics offers a wide variety of current sensing products from the industry to military
standards, such as current sense in Thin-Film / Thick-Film Technology, Bare Element Resistors,
and Open Air Shunts. This enables Token to present an astounding number of possible solutions
for any circuit design needs.
Applications of Current Detecting Resistors
Token’s TCS and CS Series unique form factor provides automotive designers with several
advantages. Both TCS and CS Series are ideal for applications involving window lift motors,
fuel pump systems, seat belt pretensioners, and pulsewidth modulator feedback.
The wider resistive element and lower resistance enables higher current to pass through the device.
Token’s LRC ultra low ohmic metal strip chip series provides the inherent ability to flex slightly and
offers stress relief during extreme temperature cycling on typical or metal substrates. This LRC series
is suitable for switch power supply applications (DC-DC Converter, Charger, Adaptor) and power
management of monitor.
The open air design of bare element resistor LRA and LRB Series provide a far cooler operation by
allowing more air flow under the resistive element to keep excess heat from being transmitted to the
PC board. They are suitable for high power AC/DC detection of power supply circuit.
Token axial moulded BWL series provides power rating up to 10 watts and lower resistance 0.005Ω,
is ideal for all types of current sensing applications including switching and linear power supplies,
instruments and power amplifiers.

Generally, a resistor manufacturer will offer their most popular devices as standards creating a
reference for Engineers to design from. Typically, and especially true in the Current Sensing category,
a standard device is available for most common applications. However, for applications requiring
parameters that are not currently considered industry standards, Token is uniquely equipped to offer
design and development services at comparatively lower costs than our competitors. In this case, the
following information is required to effectively design a current sensing resistor:

Design & Select Current Sense Resistors
Design & Select
Current Sense
Resistors
Point 1 - Power Rating
Calculate the power dissipation under operating conditions
Equation: Pavg = IRMS2 × R; where Power (P), Current (I), Root Mean Square (RMS),
Resistance (R).Allowing for transient or fault conditions and high ambient temperature if applicable,
select the required power rating.For many current sense products, only the maximum temperature of
the solder joints limits the power rating.Power rating is thus a function of the PCB layout design as
well as of component selection (see point 4.).
Point 2 - Resistance Value
Determine the minimum suitable resistance value. This is the lowest value of peak sense voltage
consistent with an acceptable signal to noise ratio, divided by the peak current to be measured.
Point 3 - Temperature Coefficient of Resistance (TCR)
Establish the accuracy needed in terms of a tolerance on the value and of sensitivity to temperature.
The latter factor is quoted as Temperature Coefficient of Resistance (TCR), defined as the value
change in parts per million for a 1°C temperature rise. It is generally higher for low value resistors
because the metallic leads or terminations, which have a very high TCR, make up a significant part of
the total resistance value.
To achieve acceptable accuracy it is normally necessary to make four-terminal (Kelvin) connections
to the resistor. This means connecting the current carrying tracks and the voltage sense tracks directly
to the component pads. Even when this is done, there is still some pad area and solder in series with
the resistor, which may compromise the actual tolerance and TCR of the soldered part. For very high
accuracy or very low values, a four-terminal resistor type is the best choice.
Point 4 - PCB Layout
Care must be taken when laying out a PCB if the stated performance of a sense resistor is to be
achieved. The current carrying tracks should be as wide as possible, using multiple layers connected
by many vias near the component pad. This also improves the heatsinking of the joints.
The best way to make four-terminal connections to a two-terminal through-hole resistor is to use
different sides of the PCB for the current and voltage connections. Failing this, current and voltage
tracks should connect to opposite sides of the component pad.

Design & Select Current Sense Resistors
In order to avoid interference from stray magnetic fields, the loop area contained by the sense resistor, the
voltage sense tracks and the sense circuit input should be minimised. This means keeping the sense
circuitry as close as possible to the sense resistor and running the voltage sense tracks close to each other.
Point 5 - High Frequency Applications
Where transient or AC currents involving high frequencies are to be sensed, the self-inductance of the
resistor must be minimised. Wirewound or spiralled film parts should be avoided, in favour of bulk metal
or low value chips.
Point 6 - High Heat Dissipation
When using a metallic element shunt with high heat dissipation and low sense voltage, consideration may
need to be given to thermoelectric voltages. The junction between a metallic resistance element and metal
terminations acts as a thermocouple, generating a voltage proportional to the temperature difference across
it.
A leaded metallic element sense resistor is therefore like two thermocouples back to back. This means that,
if the temperature differences across both junctions are equal, the error voltage is cancelled out. This is
achieved by making the design thermally symmetrical, namely, by presenting both terminals with similar
heatsinking and by keeping any other heat sources thermally distant.

of Current Sensing
Resistors
What is a Current Sensing Resistor
Current sensing products are the newest and fastest growing resistive products in the industry today.
As with most passive products, the majority of new designs are surface mount. These resistors are
used to monitor the current in a circuit and translate the amount of current in that circuit into a voltage
that can be easily measured and monitored.
Current Detecting Resistors
Due to the increase in sales of notebook PCs, the demand for the DC/DC converter has shown rapid
growth because of its high-energy conversion efficiency, and its precise current-limiting capability.
However, to ensure the performance of the multiple output DC/DC converter, the current limiting
voltage must be detected precisely to protect an expensive notebook PC from an overload, which is
generally due to shorts within the capacitors used in these devices.
For high-energy conversion efficiency various control ICs have been developed that utilize resistive
components. To achieve the perfect cutoff mode of the DC load current at the programmed
current-limiting voltage of the control IC, a very stable and accurate sense resistor with the
following characteristics is required for precise voltage comparison.
● Very Low Ohmic Value should be below 25mΩ for minimizing power consumption at the current
sensing resistor.
● Tight Tolerance must be ±1% or tighter for maximizing the current supply within the limit of
accept able current.
● Low TCR is required for current sensing across the ambient temperature range of 0°C to 60°C.
● Low Thermal EMF for an accurate comparison between the programmed current-limiting voltage
of the control IC and the detected voltage.
Furthermore, the self-inductance should be for high frequency applications. Recommended types are
general purpose current sensing products or a flame retardant type.

How Four Terminal Sense Resistor Work
High precision resistors used for current sensing are usually low ohmic value devices suitable for four
terminal connection. To use a 4-terminal resistor, we force a current from Terminal 1 to Terminal 2. It’s
current, so the unknown resistances attached to Terminal 1 and Terminal 2 don’t affect the amount of the
current. The same number of electrons per second flow through from T1 to T2, regardless of the resistance.
A voltmeter measures the resulting voltage drop across the ultra-precise resistor, measuring through the
unknown resistors attached to Terminal 3 and Terminal 4. The voltmeter’s input impedance is very, very
high compared to the unknown resistors, so the unknown resistors have essentially zero effect (typically
less than 0.1 parts-per-million).
So the current flows through the 0.100 ohm resistor, unaffected by the unknown resistors, and we measure
the voltage across the 0.100 ohm resistor, unaffected by the unknown resistors. And that’s how a 4-terminal
resistor works!

Preview
Providing design engineers with an economical low
ohmic value, current sense metal strip chip resistor
with high quality performance, Token Electronics
LRC Series is suitable for applications in the
automotive sector for applications that require high
power handling (Up to 3W) and low resistance 0.5mΩ.
From a certified supplier offering the automotive
quality, Token’s LRC Series gives all round superior
performance for current sensing in lamp detection,
mirrors, window lift, steering and seat controls.
As a first instance, the LRC Series displays enhanced
power handling capabilities, against other technologies.
Thermal conductivity is important for chip resistors - little heat is dissipated directly into the air, and instead, is
conducted out through the solder pads.
The heat generated from the specially constructed LRC resistor is more readily dispersed, therefore preventing
localised heating, which contributes to TCR and thermal EMF errors, premature aging and possible scorching of
the PC board.
They are rated for ambient operation from -55°C to +170°C.
The LRC Series is RoHS compliant and lead free. Contact us with your specific needs.

Token Electronics has launched the CS series, a family of ultra small low-value current-sense surface-mount
chip resistors. These smaller sizes save space on the circuit board, allowing the production of smaller and lighter
products.
The new series complements Token’s existing LRC Series, offering metal resistive film on ceramic construction
but providing increased choice for product designers in the form of more smaller sizes options of 0201, 0402,
0603, 0805, 1206, 2010, 2512, 1225, 3720, and 7520.
Designed for current detecting in power electronic systems, the fully RoHS compliant CS series is suitable for a
range of applications including the monitoring of power usage and battery life; and provision of output protection
for power supplies; as well as for a range of consumer and automotive products such as satellite navigation,
handheld PDAs and digital set-top boxes.
The series offers ohmic values as low as 1mΩ to minimise power consumption and has an ambient temperature
range of -55°C to +155°C.
Exhibiting a resistance range up to 1Ω and excellent heat dissipation qualities, the series offers designers
enhanced power handling capabilities and protection from the threat of localised heating, resulting in the
production of a more energy efficient product.
As demand continues to grow for reduced size, handheld and portable devices operating at low voltages,
designers will look to manufacturers to produce smaller and smaller current sense resistors. Token expects that
demand for its latest range of small size resistors will be high.

TCS Surface Mount Resistors Make Sense of Current
Preview
The trend towards smaller handheld and portable electronics equipment has also increased the need for ultra
small current sensing resistors. Devices from the Token Electronics’ TCS series use a thin film construction that
enables them to achieve precision resistance tolerances, low noise and long-term stability.
The Token TCS Series precision resistors are nichrome thin film chip resistors with a temperature coefficient of
resistance of just ±50PPM/°C and tolerances of ±0.5%.
They offer excellent stability at high frequencies and are suitable for operating high voltages with more options
in the smaller form sizes of 0402, 0603, 0402, 0805, 1206, 2010, and 2512.
The full range of values is from 50mΩ to 1Ω. This low ohmic devices are particularly suited to car engine

LRA Low Ohmic Open Air Resistors
Low Ohmic
Open Air Resistors
Low Ohmic Open Air (LRA) Resistors
Feature Longer Thermal Path
Preview
Token’s current sense LRA open air resistors are expected to
gain wide acceptance in the worldwide market as a result of
increased thermal management capabilities.
The LRA Series is designed for applications requiring the
transfer of heat away from circuits and solder joints. Available in 0.5W, 1W, and 1.5W rating, the resistor is being
specified for current sensing, feedback, current detective,
supper low inductance, as well as surge and pulse applications.
The hot spot on the LRA resistor is approximately 0.2 degrees
higher than on a typical metal strip chip resistor. This results
in an increased thermal path for the LRA, reducing heat
transfer into the solder joints and circuits.
The flameproof LRA Series resistors are constructed of a wire resistive element with welded copper leads
to prevent solder wicking, which can change the device’s resistance value in the circuit by as much as 30%.
Because of this, the device is ideal for thermally harsh environments, including automotive and aerospace
applications, as well as enclosed, poorly ventilated circuits in applications such as laptop computers.
The LRA Open Air Series feature a reduced pitch, or spacing between the leads on the circuit board (with a
corresponding increase in the board mounted profile), when compared to the standard Token LRB Series devices.
The LRA resistors are rated for 1W or 1.5W at 70°C, with resistance values from 0.1Ω to 0.003Ω and tolerances
down to ±1%. Operating temperature range is -50°C to 300°C. The LRA Series is available in bulk packaging in
200 increments.
Token will also produce devices outside these specifications to meet customer requirements. A lead-free RoHScompliant version is available, as is a non-inductive version for high frequency applications. Contact us with
your specific needs.

- Radial leads.
- Non-inductance.

OAR Open Air Current Sense Resistors
Open Air
Current Sense Resistor
Token’s “tight pitch” version of its open air metal element
current sense resistor (OAR) need less PCB space.
Preview
In response to requests from power electronics design engineers
with the means to squeeze more current-sensing capability
into crowded power supply designs, Token Electronics has
developed a “tight pitch” version of its open air metal element
current sensing resistor with ratings as high as 5W in a
reduced PC board footprint and longer thermal path.
Designated the OAR Series, these open-air through-hole
devices offer a high current, flameproof alternative to
conventional axial devices and flat chips for current-sense
circuits where PC board space is at a premium. The resistor’s
footprint is reduced by extending the height of the device
above the board, thus keeping the resistor element’s “hot spot” safely off the PC board and providing for
increased air circulation under it, which in turn provides increased heat dissipation and cooler operation.
The OAR devices with increased height improve cooling efficiency, and because many power supply designs are
already tightly-packed at the PC board level, the additional height does not create any profile issues. The OAR
series resistors feature a reduced pitch, or spacing between the leads on the circuit board with a corresponding
increase in the board mounted profile.
The OAR Series resistors are power rated for 1W, 2W, 3W, or 5W at 85°C, with resistance values from 0.05Ω
to 0.005Ω, with tolerances down to ±1%. They feature TCRs as low as ±50ppm/°C and inductance values in the
single-digit nanohenry range (10 nH Max.). Operating temperature range is -40°C to +125°C. The flameproof
OAR resistors are constructed of a wire resistive element with welded copper leads to prevent solder wicking,
which can change the device’s resistance value in the circuit by as much as 30%.
The OAR Series is available in bulk packaging and is RoHS compliant and lead free. For non-standard technical
requirements and special applications,please contact us with your specific needs.

FL Current Shunt Resistors
Current Shunt
Resistors
Token’s Shunt Resistors (FL)
for high-current applications aid precision measurement.
Preview
Current shunt resistors are low resistance precision
resistors used to measure AC or DC electrical
currents by the voltage drop those currents create
across the resistance. Sometimes called an
ammeter shunt, it is a type of current sensor.
A wide range of precision shunts, designed for
use with kilowatt-hour meters and other
high-current applications where a high level
of accuracy is required, is now available from
Token Electronics.
The interchangeable shunts (FL) are used to
multiply the measuring range of measuring
instruments and designed for PCB and busbar mounting, are manufactured from electron beam welded copper
and manganin, and have low temperature coefficients. Featuring low inductance values, shunts FL series can
handle permanent currents of up to 10000A at voltage 75 mV.
FLQ-54 type shunt is made of precision alloy board. It’s copper terminals spot welded by silver alloy ensure
extremely high electric capability. The construction provides a kind of excellent stability and high overloaded
ability non-inductive resistor, applied widely as current limited, current balance or sampling sense in
communication system, electric equipment and auto-controlling electrical circuit.
The FL Series is available in bulk packaging and is RoHS compliant and lead free. For non-standard technical
requirements and special applications, please contact us with your specific needs.
Power Rating : Watts (W) = Current (I2) x Resistance Value (R)
- The heat produced is power measured in Watts (W).
- In practice current shunts are often rated to be used continuously at only 2/3 of their “rated current”.
- Because current shunts are resistors and dissipate heat from the current flowing through them, they get hot.
- Since that heat can change their resistance and even permanently damage the shunt, current shunts are often
given a power rating or a derating factor.
Calculate Current : Current (I) = Voltage (V) / Resistance Value (R)
- Then knowing the resistance of the current shunt you can calculate the current using Ohm’s law.
- By inserting a current shunt into a circuit whose current you want to measure your can find the current by
measuring the voltage drop across the shunt.

LSQ Open Air Current Sense Resistors
Kelvin Four Terminal
Resistors
Token (LSQ) Family Four Terminal Resistors
handle high-wattage applications
Preview
Providing ultralow resistance values (to 0.01 ohm) for
relatively high current requirements, new four-terminal
cement filling resistors from Token combine the
advantages of a Kelvin configuration with PC board
mounting capability.
The Kelvin (or four-terminal) configuration enables
current to be applied through two opposite terminals and
a sensing voltage to be measured across the other two
terminals, eliminating the resistance and temperature
coefficient of the terminals for a more accurate current
measurement.
The four terminal resistors are a new version of Token’s (LSQ) Current Sense Family Series which was specially
designed for use in a Kelvin configuration where a current is applied through two opposing leads and sensing
voltage is measured across the other two leads. Token LSQ series is specifically designed for low resistance
applications requiring the highest accuracy and temperature stability.
The advantages of Kelvin configuration enable the resistance and temperature coefficient of the leads to be
effectively eliminated. The need to connect to the leads at precise test points is eliminated, allowing for tighter
tolerance on the end application. Also results in a lower temperature coefficient of resistance and lower
self-heating drift which may be experienced on two-terminal resistors.
Token will also produce low ohm resistor LSQ series outside these specifications to meet customer requirements.
Contact us with your specific needs.
Features
Applications
- Welded & fireproof construction.
- Superior anti-surge capability & Low TCR.
- Thermal conductivity and moisture resistance.
- Special inorganic potting construction provides
high moisture resistance and thermal conductivity.
- 4 leads for Kelvin connection with extremely

Possibilities for Shunt-Resistors
Preview
Token’s current sense LPS family for shunt-resistors is
expected to gain wide acceptance in the worldwide market
as a result of offering a variety of possibilities.
The U-shaped semi-customized LPS family for direct board
mounting is specified for current sensing, feedback, current
detective, supper low inductance, as well as surge and pulse
applications. LPS family Available in very low ohm
(0.002Ω ~ 0.05Ω) and high power (1W ~ 5W).
The dimensions of the semi-customized final unit is designed
in accordance with the applicational requirements of resistance
value and required power rating. Token’s LPS series can be
manufactured with 2 or 4 soldertags (terminals). The LPS type B with 2 soldertags (1 pin on each side) is a
standard part of LPS series and type A with 4 terminals (2 pin on each side) is used either for Kelvin connections
or for high current applications. Depending from the alloy material’s thickness, one terminal contact on each
side can carry up to 50A (A (Current) = (W (Power)/Ω (Resistance))1/2), so a 4-terminal part can carry 100A (ask
Token factory).
