High current shunts capable of high-temperature operation

As power electronics evolve, the need for high current, low resistance sensing resistors continues growing. For industrial power control and automotive engine controls, high-temperature operation is needed. Due to their technology, many surface mount current sense resistor options have limited high-temperature capability.

The company's HCS series delivers high power handling, precise sensing, and the ability to operate at higher temperatures efficiently and reliably. The series offers power ratings up to 10W up to 100C, whereas many sense resistors are only rated for full power operation up to 70C.

The raised resistance element improves the thermal footprint of the device and decreases PCB and terminal temperature. The resistance values as low as 0.2milliohms ensure high efficiency sensing in a surface mountable package. The all-metal construction also supplies high pulse withstanding and the potential for operation up to 170C instead of 155C.
