The resistors operate over a temperature range from -65 to +155°C and are also AEC-Q200 qualified. Applications for PSI and PSE power shunt resistors include electronic controls, EV/HEV battery management, DC/DC converters, oil and gas down hole, inverter controls, and automotive uses in electronic power steering, electric brakes and water/oil pumps.
KOA’s power shunt resistors feature a flat rectangular structure for strong mounting and T.C.R. values of ±50 and ±150ppm/°C for effective operation over a wider temperature span and greater stability under load. They deliver dependable performance with a resistance range of 0.5-4mΩ and tolerances of ±1 and ±5%.
Available with with lead-free terminations, the devices meet EU RoHS and China RoHS requirements. Lead times are 12-14 weeks.
