Select Bourns® power metal strip current sense resistors are now AEC-Q200 qualifi ed for automotive applications. These SMT chips have a low temperature coeffi cient to help ensure a stable operating accuracy over wide temperature ranges.

Current sense resistors are growing in popularity due to their high measurement accuracy and

relatively low cost compared to other technologies. These resistors detect and convert current to an easily measured voltage which is proportional to the current through the device.

For higher current measurement accuracy Bourns offers 2-terminal resistors that can be used with additional current sensing trace on the PCB as well as 4-terminal resistors. The current sense resistors complement the other circuit conditioning components offered by Bourns such as power inductors, rectifi er diodes and zener diodes.
