IRC Current Sense Resistors: ULR Series

The ULR series of sense resistors from IRC are designed with low TCR and inductance for current sense circuits in power electronic systems. The ULR series feature 1W to 3W power ratings in 2512 chip sizes and a 0.5mO to 10mO resistance. The higher wattage devices feature PCB clearance gap to maximize thermal performance.
