High sensing accuracy for high currents requires low resistance values. However, not all applications or power topologies are able to use the lowest resistance values. Because of the wide range of power delivery designs, some power platforms need specific resistance values. Stackpole recently added the 0.7 milliohm value to their popular HCSK2725 size to further enhance the range of power supply designs supported.Stackpole’s HCSK offers a raised element to lower the terminal temperature and reduce the thermal impact on the PCB. In addition, the HCSK offers power ratings up to 12 W in resistance values as low as 0.2 milliohm for maximum sensing efficiency under high current loads. The HCSK has a low TCR of 50 ppm, which also minimizes the effects of temperature on sensing accuracy, and the all-metal element and welded construction have exceptional pulse handling.
Pricing for the HCSK varies with size, value, and tolerance. Contact Stackpole or one of our franchised distribution partners for volume pricing.
