For high-efficiency applications, low resistance values are crucial to minimise power dissipation. However, achieving accurate current sensing at low resistance values can be challenging due to lead resistance. Stackpole’s HCSK series addresses this with a four-terminal shunt design, eliminating lead resistance effects and ensuring precise measurements.
The HCSK features a raised element that lowers terminal temperatures, reducing thermal stress on the PCB. With power ratings up to 12W and resistance values as low as 0.2 milliohm, it maximises sensing efficiency under high current loads. Its low TCR of 50 ppm minimises temperature-induced inaccuracies, while the all-metal element and welded construction offer superior pulse handling, making the HCSK an ideal solution for demanding applications.
Pricing for the HCSK varies with size, value and tolerance. Contact Stackpole or one of our franchised distribution partners for specific or volume pricing.
