Metal Alloy Resistors Offer Robustness And Other Benefits For Current Sensing

Focus:

For current-sensing applications, metal alloy resistors provide a more robust technology than thick film devices. Although metal alloy resistors have been around for decades, their capabilities have evolved to offer higher power ratings, extended resistance ranges, and Kelvin connections for increased accuracy. Vishay’s Power Metal Strip resistors feature the Kelvin connection in combination with the ability to operate at very high temperature (275°C) and tight tolerance (0.1%). This article offers background on how the different resistor technologies (mainly thick film and metal alloy) compare with respect to current sensing and discusses the specific features of the Power Metal Strip series.
