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.
