HCSK High-Current Surface-Mount Shunts with Kelvin Terminations

Stackpole adds 1216 and 4026 sizes to HCSK high current surface mount shunts with Kelvin terminations

Image of Stackpole's HCSK High Current Surface Mount Shunts Stackpole's HCSK is an all metal surface-mount current shunt with Kelvin terminations for high accuracy, low resistance sensing. Recently added to the HCSK series are the 1216 and 4026 sizes, both rated from 3 W to 5 W depending on resistance value. The HCSK is capable of full-power operation at ambient temperatures up to +100°C and provides cooler operation due to the raised element design. The robust HCSK is available in 1% and 5% tolerances and 50 ppm TCR with excellent demonstrated stability over life, high-temperature exposure, moisture resistance, rapid change of temperature, and short time overload testing.

The HCSK range has been expanded to include 0.5 milliohm, 0.7 milliohm, 1 milliohm, 3 milliohm, 4 milliohm, and 5 milliohm values depending on size. This surface mount shunt is suitable for sensing currents up to 70 amps as lead resistance is eliminated with the 4-pin connection. The high temperature capability, accuracy, and stability is ideal for applications including power modules, frequency converters, motor controls, hybrid power current sensing, and automotive engine controls and management.
