Ohmite FCSL90R050FER Metal Foil Current Sense Resistor

Ohmite's FCSL series metal foil current sense resistors utilize proven metal foil technology to deliver exceptional stability and performance. Featuring very low and stable Temperature Coefficient of Resistance (TCR) and available in a wide selection of low ohmic values, FCSL resistors are ideal for precision current sensing applications. With power ratings up to 10 Watts and designed for automatic insertion, these resistors provide a reliable and efficient solution for demanding industrial and commercial applications. They are characterized by their foil construction, high heat resistance, and low heat electromotive force, ensuring accurate and consistent current measurement.
