Current measurement is a fundamental requirement in many automotive application.

Depending on the circuit application, current sensing could be needed in order to regulate an output voltage of DCDC converter, to regulate a motor current (high motor revolution-> high current-> high speed, low motor revolution-> less current-> less speed) or to detect a short circuit which will prevent the electronic system to get damage. Panasonic offers a wide range of Current Sensing Resistors in a variety of case sizes (0402 to 2526), and resistance values.

Metal plate technology (ERJM-series) could achieve lower resistance value(0.5mOhm-1Ohm) , high power rating, low temperature coefficient which makes them suitable for application where high current measurement accuracy is required. Double sided resistor technology (ERJxBW-series) & wide terminal technology (ERJA, ERJB-series) for high power purpose. Furthermore all Panasonic Current Sensing Resistors are automotive qualified AEC-Q200 and therefore are ideal solution for all different kind of automotive applications.
