RALEIGH, NC (May 1, 2024) – High-efficiency applications, such as high-end data servers, rely on low resistance values to minimize wasted power. Sensing accuracy becomes challenging when the application utilizes a value of 5mΩ or less due to the significant impact of lead resistance. However, a four-terminal shunt resistor effectively eliminates the detrimental effects of lead resistance on current sensing measurements.
Stackpole’s HCSK2725 offers engineers a solution to overcome the obstacles of accurate sensing measurement in low-value applications. The HCSK2725 features a raised element to lower terminal temperature and reduce thermal impact on the PCB. Moreover, it boasts a small footprint and up to 5-watt power ratings in resistance values as low as 0.2 milliohm, ensuring maximum sensing efficiency at high server current loads. With a low TCR of 50 ppm, the HCSK2725 also minimizes the effects of temperature on sensing accuracy. Its all-metal element and welded construction provide exceptional pulse handling capabilities.
Pricing for the HCSK2725 starts at around $0.50 each in minimum quantities. For volume pricing, please contact Stackpole or one of our franchised distribution partners.
