 Customized Resistance Available.
 Resistance Values from 0.5mΩ to 15mΩ.
 Without Laser Trimmed with Very Low
Inductance.
Applications :
 For NB power management.
 For MB power management.
 For Monitor power management.
 SWPS: DC-DC converter, Charger, Adaptor.
Providing design engineers with an economical low Ohmic value,
metal strip current sense surface mount 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 localized heating, which contributes to TCR and thermal EMF errors, premature aging and
possible scorching of the PC board.
The current sensing resistors (LRC) are rated for ambient operation from -55℃ to +170℃. The LRC
Series is RoHS compliant and lead free.

Resistors”. Contact us with your specific needs.

 General Information
Your Current Options - Token Current Sense
As the world becomes more and more technology-driven, the uses for current sensing components 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 Components
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 pulse width 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, and 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.
Token standard current sensing components can be replacement for Vishay, IRC, Ohmite, KOA, Yageo
devices with fast delivery and more competitive price. Contact us with your specific needs.
