Stackpole's HCS series is a high current surface mount chip designed for accurate current sensing at high currents. The HCS combines an elevated resistive element to lower the induced heat on the PCB with low resistance values down to 0.3 mΩ to achieve this outstanding performance. The HCS has low TCR ranging from 50 ppm to 150 ppm for high accuracy even at high temperatures. The HCS is designed to handle and operate at high temperatures; it is rated for full power up to 100°C and can operate safely at reduced power up to 170°C.

The HCS is a good choice for all types of high power supplies and power modules, electric motor controls, fuel powered engine controls, DC-to-DC converters in switching power supplies, frequency converters, voltage regulators, portable power management, and battery monitoring.
