Current Sensing & Shunt Solutions
Low inductance. Wide temperature range.
Low-inductance current sensing for BMS, power inverters, energy meters, and IGBT modules - rated from −50 °C to +150 °C.
PML's automotive shunt resistors deliver accurate, stable current measurement across busbar and SMD form factors. Built with copper construction and a ±50 ppm/K TCR, the full range covers 50 µΩ to 1 mΩ resistance and operates reliably from −50 °C to +150 °C. Available in configurations for direct busbar mounting, PCB integration via solderable pins, DBC/IMS substrates, and surface-mount assembly - with custom resistance values available on request.
