Current Sensing Resistor

The BSS current & voltage sensing resistor series from Isabellenhütte has a built-in PCB with a Molex DuraClik connector. This shunt resistor offers low resistance value of 100µΩ making these parts ideal for battery management systems (BMS) or energy storage systems (ESS). The BSS series is capable of handling a continuous load up to 450A with a power rating of 20W and a peak pulse power rating of up to ±3,500A for a maximum of 100ms. All of this is based on a package size of 8420.
