NTC Thermistors
General Characteristics
1 – INTRODUCTION
NTC thermistors are thermally sensitive resistors made from
a mixture of Mn, Ni, Co, Cu, Fe oxides. Sintered ceramic
bodies of various sizes can be obtained. Strict conditions
of mixing, pressing, sintering and metallization ensure an
excellent batch-to-batch product characteristics.
This semi-conducting material reacts as an NTC resistor,
whose resistance decreases with increasing temperature.
This Negative Temperature Coefficient effect can result from
an external change of the ambient temperature or an internal heating due to the Joule effect of a current flowing
through the thermistor.
By varying the composition and the size of the thermistors,
a wide range of resistance values (0.1Ω to 1MΩ) and temperature coefficients (-2 to -6% per °C) can be achieved.
RoHS (Restriction of Hazardous Substances - European
Union directive 2002/95/EC).
ELV (End of Life-Vehicle - European Union directive
2000/53/EC).
All Thermistor Products have been fully RoHS/ELV since
before 2006.

2 – MAIN CHARACTERISTICS
The nominal resistance of an NTC thermistor is generally
given at 25°C. It has to be measured at near zero power
so that the resultant heating only produces a negligible
measurement error.
The following table gives the maximum advised measurement voltage as a function of resistance values and thermal
dissipation factors.
This voltage is such that the heating effect generated by the
measurement current only causes a resistance change of
1% ΔRn/Rn.

This is the relation between the zero power resistance and
the temperature. It can be determined by experimental measurements and may be described by the ratios R (T) /R
(25°C) where:
R (T)
is the resistance at any temperature T
R (25°C) is the resistance at 25°C.
These ratios are displayed on pages 29 to 33.

curve at a given point is defined by:

and expressed in % per °C.
2.1.4. Sensitivity index (B)
The equation R = A exp (B/T) may be used as a rough
approximation of the characteristic R (T).
B is called the sensitivity index or constant of the material
used.
To calculate the B value, it is necessary to know the resistances R1 and R2 of the thermistor at the temperatures
T1 and T2.

leads to:
B (K) =
• ᐍn
1-1
R2
T1 T2
Conventionally, B will be most often calculated for temperatures T1 = 25°C and T2 = 85°C (298.16 K and 358.16 K).
In fact, as the equation R = A exp (B/T) is an approximation,
the value of B depends on the temperatures T1 and T2 by
which it is calculated.
For example, from the R (T) characteristic of material M
(values given on page 29), it can be calculated:
B (25 – 85) = 3950
B (0 – 60) = 3901
B (50 – 110) = 3983
When using the equation R = A exp (B/T) for this material,
the error can vary by as much as 9% at 25°C, 0.6% at 55°C
and 1.6% at 125°C.
Using the same equation, it is possible to relate the values of
the index B and the coefficient α:

2.1.5. Further approximation of R (T) curve
The description of the characteristic R (T) can be improved
by using a greater number of experimental points, and by
using the equation:
1 = A + B (ᐍn R) + C (ᐍn R)3
T
The parameters A, B and C are determined by solving the
set of equations obtained by using the measured resistances at three temperatures.
The solution of the above equation gives the resistance at
any temperature:
[冑

Thus, the tolerance on the resistance (⌬R2/R2) at a temperature T2 is the sum of two contributions as illustrated on
Figure 1:
– the tolerance ⌬R1/R1 at a temperature T1 used as a
reference.
– an additional contribution due to the dispersion on
the characteristic R (T) which may be called
“Manufacturing tolerance” (Tf).

The precision of this description is typically 0.2°C for the

temperature range is reduced. The ratios R(T)/R(25°C) for
each of the different materials shown on pages 29 to 33
have been calculated using the above method.

2.1.6. Resistance tolerance and temperature
precision
An important characteristic of a thermistor is the tolerance
on the resistance value at a given temperature.
This uncertainty on the resistance (DR/R) may be related to
the corresponding uncertainty on the temperature (DT),
using the relationship:
⌬R 1
⌬T = 100 • R • ␣
Example: consider the thermistor ND06M00152J —
• R (25°C) = 1500 ohms
• Made from M material
• R (T) characteristic shown on page 23 gives:
␣ = - 4.4%/°C at 25°C
• Tolerance ⌬R/R = ±5% is equivalent to:
⌬T = 5%/4.4%/°C = ±1.14°C
2.1.7. Resistance tolerance at any temperature
Any material used for NTC manufacturing always displays a
dispersion for the R (T) characteristic.
This dispersion depends on the type of material used
and has been especially reduced for our accuracy series
thermistors.

The T(f) values given with the resistance – temperature
characteristics on pages 29 to 33 are based on a computer
simulation using this equation and experimental values.
2.1.8. Designing the resistance tolerances
Using the fact that the coefficient ␣ decreases with temperature (α = –B/T2), it is generally useful to define the closest
tolerance of the thermistor at the maximum value of the
temperature range where an accuracy in °C is required.
For example, let us compare the two designs 1 and 2

NTC Thermistors
General Characteristics
2.1.9. Shaping of the R (T) characteristic
By the use of a resistor network, it is possible to modify the
R (T) characteristic of a thermistor so that it matches the
required form, for example a linear response over a restricted temperature range.
A single fixed resistor Rp placed in parallel with a thermistor
gives a S–shape resistance–temperature curve (see Figure 2)
which is substantially more linear at the temperature range
around the inflexion point (Ro, To).

2.2 CHARACTERISTICS WITH ENERGY
DISSIPATION
When a current is flowing through an NTC thermistor, the
power due to the Joule effect raises the temperature of the
NTC above ambient.
The thermistor reaches a state of equilibrium when the
power supplied becomes equal to the power dissipated in
the environment.
The thermal behavior of the thermistor is mainly dependent
on the size, shape and mounting conditions.
Several parameters have been defined to characterize these
properties:
2.2.1. Heat capacity (H)
Rp
The heat capacity is the amount of heat required to change
the temperature of the thermistor by 1°C and is expressed in
J/°C.
Rp
2.2.2. Dissipation factor (␦)
This is the ratio between the variation in dissipated power
and the variation of temperature of the NTC. It is expressed
in mW/°C and may be measured as:
U.I
␦=
85 – 25
RO
TO
T (°C)
Figure 2 – Linearization of a thermistor
where U.I is the power necessary to raise to 85°C the temperature of a thermistor maintained in still air at 25°C.
2.2.3. Maximum permissible temperature (T max)
It can be calculated that better linearization is obtained when
the fixed resistor value and the mid-range temperature are
related by the formula:
B – To
Rp = R x
To
B+ 2To
This is the maximum ambient temperature at which the thermistor may be operated with zero dissipation. Above this
temperature, the stability of the resistance and the leads
attachment can no longer be guaranteed.
For example, with a thermistor ND03N00103J —
R 25°C = 10kΩ, B = 4080 K
good linearization is obtained with a resistor in parallel where
the value is:
4080 - 298
Rp = 10,000 Ω x
= 8088 Ω
4080 + (2 x 298)
This is the power required by a thermistor maintained in still
air at 25°C to reach the maximum temperature for which it is
specified.
For higher ambient temperatures, the maximum permissible
power is generally derated according to the Figure 3 hereafter and TL = Tmax – 10°C.

NTC Thermistors
General Characteristics
2.2.5. Voltage – Current curves V (l)
2.2.7. Thermal time constant
These curves describe the behavior of the voltage drop V
measured across the NTC as the current l through the NTC
is increased.
They describe the state of equilibrium between power
resulting from Joule effect and dissipated power in the
surroundings. (Figure 4)
When a thermistor is self-heated to a temperature T above
ambient temperature Tamb, and allowed to cool under zero
power resistance, this will show a transient situation.
At any time interval dt, dissipation of the thermistor
(␦(T – Tamb)dt) generates a temperature decrease –HdT,
resulting in the equation:
1
␦
dT = dt
(T - Tamb)

The solution to this equation for any value of t, measured
from t = 0, is:

Figure 4 – Voltage – current curve V (l)
Several zones can be identified:
– low current zone
dissipated energy only produces negligible heating and
the curve V (l) is almost linear.
– non-linear zone
the curve V (l) displays a maximum voltage Vmax for a
current lo.This maximum voltage Vmax and the temperature Tmax reached by the NTC under these conditions
can be determined by using the equations:
and
P = V2/R = ␦ (T - Tamb)
R = Ramb • exp B (1/T - 1/Tamb)
therefore:

冑 ␦ (Tmax - Tamb ) • Ramb exp [B(Tmax

where ␦ is the dissipation factor and Tamb is the ambient temperature.
– high current zone
for higher currents, an increase in temperature of the
NTC decreases the resistance and the voltage more
rapidly than the increase of the current. Above a certain
dissipated power, the temperature of the NTC exceeds
the permissible value.
We can define a thermal time constant ␶ as:
␶ = H/␦
expressed in seconds.
Where the time t = ␶ :
(T - Tamb) / (To - Tamb) = exp - 1 = 0.368
expressing that for t = ␶, the thermistor cools to 63.2% of the
temperature difference between the initial To and Tamb (see
Figure 5).
According to IEC 539 our technical data indicates ␶ measured with To = 85°C, Tamb = 25°C and consequently
T = 47.1°C.

2.2.8. Response time
More generally, it is possible to define a response time as the
time the thermistor needs to reach 63.2% of the total
temperature difference when submitted to a change in the
thermal equilibrium (for example from 60°C to 25°C in
silicone oil 47V20 Rhodorsil).
2.2.6. Current – Time curves l(t)
When voltage is applied to a thermistor, a certain amount of
time is necessary to reach the state of equilibrium described
by the V(l) curves.
This is the heating up time of the thermistor which depends
on the voltage and the resistance on one side and the heat
capacity and dissipation on the other.
The curves l(t) are of particular interest in timing applications.

NTC Thermistors
Application Notes
TEMPERATURE MEASUREMENT
Thermistor
circuit
High sensitivity and low cost make NTC thermistors the most
common device used for temperature measurement.
Non-linearity of the R -T curve generally leads to the use of
a resistor network to linearize the signal. An example is
given in Figure 6.
More precise measurements and temperature display can
also be achieved with simple electronic equipment as
shown in Figure 7.
The choice of the model will particularly take into account
the small size (better response time) and the resistance
tolerance. Mounting conditions (dissipation), and input voltage (self-heating) will also be carefully defined to avoid serious
errors in temperature measurement.

NTC thermistors can be used as a simple on-off control temperature system or temperature alarm system. Figure 8 gives
an example of such a circuit.
When the temperature increases to a defined value, the
resistance of the thermistor decreases and the current
becomes sufficiently high to energize the relay and provide
temperature alarm or heating system turn-off.
The high sensitivity of thermistors (about 4% resistance
change for 1°C) allows the temperature to be controlled very
precisely.

TEMPERATURE COMPENSATION
As many electronic components (integrated circuits, amplifiers,...) have a positive temperature coefficient of resistance,
NTC thermistors represent a cheap and interesting solution
to compensate for this effect and provide an improved
temperature stability for electronic equipment.
It is necessary to include the thermistor in a resistor network
(Figure 10) calculated in such a manner that the network
coefficient compensates exactly for the positive temperature
coefficient of the other component (Figure 9).
Common leaded discs or chip thermistors are well suited for
this application.

LIQUID LEVEL OR FLOW DETECTION
The dissipation of a thermistor is significantly different in a
liquid or in a gas, in a static fluid or in a stirred one. A liquid
level detector or a gas–flow measurement can be designed
using this property.
In Figure 11, the output voltage measured on the thermistor
depends upon the dissipation factor of its environment, and
can be illustrated by V-l curves (Figure 12).
This voltage can be used to detect the presence (V2) or
absence (V1) of liquid around the thermistor or measure the
flow speed.
A good design should define a precise operating temperature
range, where dissipation in the high dissipating medium at
highest ambient temperature remains higher than the dissipation in low dissipating medium at lowest ambient temperature.

SURGE PROTECTION
A soft start of sensitive apparatus can be achieved by using
NTC thermistors as described in Figures 13 and 14.
At turn-on, the NTC absorbs the surge current, limits the
current across the equipment and protects it. Then, the
thermistor heats, its resistance decreases and most of the
power becomes applied to the apparatus.
In its design, the thermistor will be selected with a thermal
capacity higher than the surge energy to absorb.

TIME DELAY
The current-time characteristic of a thermistor is used in time
delay applications such as delaying energization of a relay
after application of power to an electrical circuit.
The time delay, time necessary for the thermistor to heat up
to the temperature where its resistance allows the current to
reach the switching value of the relay, is mainly defined with
the nominal resistance of the thermistor.
The time delay is also strongly dependent upon the ambient
temperature, as shown in Figure 15.

NTC SMD Thermistors
NC 12 – NC 20
Chip thermistors are a high quality and low cost device especially developed for surface mounting applications. They are
widely used for temperature compensation but can also
achieve temperature control of printed circuits. Its silver -
palladium - platinum metallization provides a high degree of
resistance to dewetting of the terminations during soldering
(typically 260°C / 30 s).

NB products are compatible with a wide range of soldering
conditions consistent with good manufacturing practice for
surface mount components. This includes Pb free reflow
processes with peak temperatures up to 270ºC.
Recommended profiles for reflow and wave soldering are
shown below for reference.
NC products are recommended for lead soldering application
or gluing techniques.

a) The visual standards used for evaluation of solder joints
will need to be modified as lead free joints are not as bright
as with tin-lead pastes and the fillet may not be as large.
b) Resin color may darken slightly due to the increase in
temperature required for the new pastes.
c) Lead-free solder pastes do not allow the same self alignment as lead containing systems. Standard mounting
pads are acceptable, but machine set up may need to be
modified.

PACKAGING AND KINK SUFFIXES
Tables below indicate the suffixes to specify when ordering to
get the required kink and packaging. For devices on tape, it
is necessary to specify the height (H or Ho) which is the
distance between the tape axis (sprocket holes axis) and
the seating plane on the printed circuit board. The following
types can be ordered on tape either in AMMOPACK
(fan folder) or on REEL in accordance with IEC 286-2.
– Straight leads:
H represents the distance between the sprocket holes axis
and the bottom plane of component body (base of resin or
base of stand off).
– Kinked leads and flat leads:
Ho represents the distance between the sprocket holes
axis and the base on the knee (kinked leads) or the bottom
of the flat part (flat leads).

NTC Leadless Disc Thermistors
This type of product is widely used in automotive and
consumer applications.
They are assembled in custom-probes for sensing the
temperature of liquids (water, oil, ...), gases or surface of any
other component.
The metallization covers completely the surfaces of the
thermistor.
The particularly flat and smooth surfaces ensure an excellent
electrical and thermal contact under pressure.

DESIGN OF THE THERMISTOR
Choice of the resistances
Choice of the tolerances
If the application is to measure the temperature around a
defined point, a unique nominal resistance can be chosen
(for example, among standard values of the ND range products presented on pages 20 to 24).
When it is required to measure the temperature over selected
ranges T1 –T2 , T2 –T3 , ..., the corresponding resistance
R1 , R2 , R3 , ..., must be such that they can be located
on the R (T) characteristic of an existing NTC material
(for example among standard materials whose R (T) are
displayed on pages 29 to 33).
The resistances must also be compatible with the resistivity
of the material and the dimensions of the thermistor.
The precision of the temperature measurement determines
the calculation of the tolerance on the resistance:
⌬R/R = ␣ (%/°C). ⌬T (°C)
For example, the NTC NR55--3049-99, using “N5” material
(R (T) characteristic displayed on page 31), requires a precision of 1°C over the temperature range 110°C - 120°C.
The tolerances can be calculated:
⌬R110°C /R110°C = 1°C* 2.91%/°C = 2.91%
⌬R120°C /R120°C = 1°C* 2.76%/°C = 2.76%
*For your specific requirements, please consult us.

Identification – Traceability
On the packaging of all shipped thermistors, you will find a bar code label.
This label gives systematic information on the type of product, part number, lot number, manufacturing date and quantity.
An example is given below:
Manufacturing date
(YYMMDD)
Lot number
RoHS Logo
Quantity of parts
per packaging
Product and part
number reference
This information allows complete traceability of the entire manufacturing process, from raw materials to final inspection.
This is extremely useful for any information request, customer complaint or product return.
