shunt resistorThe HCS Series shunt resistor from Stackpole (Raleigh, NC) uses a solid metal element that is elevated off the mounting plane. This elevated design increases the ability of the part to dissipate the heat into the ambient air and not into the PCB. The HCS2512, for example, will run typically 15 to 20 degrees C cooler than an equivalent flat chip, according to the company. This cooler operation combined with the low resistance values down to 0.3 milliohm and desirable TCR make the HCS Series appropriate for a wide variety of applications where high power and low operating temperatures are critical. Pricing varies with size, value, and tolerance, and ranges from $0.30 to $0.70 each in full reel quantities. Markets and applications include:

  • High density power supplies.
  • Motor and pump controls.
  • Voltage regulators.
  • Power conversion.
  • Communications equipment.
  • Green energy power controllers.
  • Instrumentation.
  • Robotics.
