High power moulded current shunt resistors offer high stability

Stackpole Electronics offers its HCSM High Power Moulded Current Shunt Resistors utilising a metal element and moulded package to provide 5W in a space-efficient 2818 package with excellent stability. These products are ideal for power management applications for frequency converters, inverters, and hybrid power modules that demand high power with environmental and electrical stability. While high power shunt resistors for current sensing are becoming more available, there is often a trade-off between high power and stable performance to deliver the higher power rating.

The HCSM shows resistance shifts of less than 1% for the industry-standard tests short time overload, high-temperature exposure, biased humidity, thermal shock, and load life, with typical performance shifts of less than 0.5%.
