The PE0805FRF470R91L is an ultra-small, surface-mount current sense resistor manufactured by Yageo. This component is designed to measure small currents in circuits, such as those created by motors, solenoids, and transformers. With a rated resistance value of 470O, a power rating of 0.1W, and a tolerance of ±1%, it can accurately measure currents up to 1 amp. It is constructed from a thin film of metal on a ceramic core, giving it a superior thermal and mechanical shock resistance. It also has an ultra-thin and ultra-small size (0805 package) that allows it to be used in the tightest of spaces. The PE0805FRF470R91L is a reliable and cost-effective solution for current measurement.
