ULR Current Sense Resistors

TT Electronics ULR Current Sense Resistors 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 0.5mΩ to 10mΩ resistance. The higher wattage devices feature PCB clearance gap to maximize thermal performance.
