High current four terminal shunts for precision power control

For high-efficiency applications, low resistance values are vital to minimise power dissipation. However, attaining accurate current sensing at low resistance values can be challenging due to lead resistance. Stackpole Electronics' HCSK series addresses this with a four-terminal shunt design, eradicating lead resistance effects and ensuring precise measurements.

The HCSK features a raised element that reduces terminal temperatures, lowering 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 50ppm minimises temperature-induced inaccuracies, while the all-metal element and welded construction deliver superior pulse handling, making the devices an ideal solution for demanding applications.
