Raleigh, N.C. – Stackpole Electronics introduces the HCS Series of shunt resistors that offer high current handling and lower self-heating. The shunt resistor series use a solid metal element that is elevated off the mounting plane, which increases the ability of the part to dissipate the heat into the ambient air and not into the printed circuit board (PCB). The HCS2512, for example, will run typically 15 to 20 degrees C cooler than an equivalent flat chip, said the company.
The cooler operation combined with the low resistance values down to 0.3 milliohm and “outstanding” temperature coefficient of resistance (TCR) make the HCS well suited for a variety of applications where high power and low operating temperatures are critical, such as high-density power supplies, motor and pump controls, voltage regulators, power conversion, communications equipment, green energy power controllers, instrumentation, and robotics.
