The HCSK is a surface-mount, metal element, high-current shunt with four terminals. Four terminal Kelvin sense resistors provide the most accurate sensing as it removes the effect of lead resistance in the sensing function. The HCSK2725 rated at 5 W at an ambient temperature of 100°C utilizes unique materials and a raised element that provides tolerances as low as 1% and TCR of 50 ppm/°C.
The robust HCSK has excellent stability over life, high-temperature exposure, moisture resistance, rapid change of temperature, and short time overload testing.
The HCSK2725 is readily available in the 1 milliohm resistance value. Other resistance values are possible based on customer demand. It is suitable for sensing currents up to 70 amps. The high-temperature capability, accuracy, and stability are ideal for applications including power modules, frequency converters, motor controls, hybrid power current sensing, E-scooters, and automotive engine controls.
