5-Watt Surface-Mount Shunts with Kelvin Terminations

Stackpole‘s new HCSK Series is an all-metal surface-mount current shunt with Kelvin terminations for high accuracy low resistance sensing. The HCSK2725 is rated at 5 Watts at ambient temperatures up to 100 degree C, utilizing unique materials and a 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 HCSK2725 is currently available in the 1 milliOhm resistance value, and is suitable for sensing currents up to 70 Amps as lead resistance is eliminated with the four pin connection.

The high temperature capability, accuracy, and stability is designed for applications including power modules, frequency converters, motor controls, hybrid power current sensing, and automotive engine controls and management.

Additional resistance values are under development and will be available in the near future. Pricing depends on tolerance and order volume, but typically ranges from $0.50 each to $0.60 each in full reel quantities.

Contact Stackpole or a franchised distributor for volume pricing and inquiries regarding other resistance values.
