ULR3N Metal Element Inverse Current Sense Resistor

Welwyn / TT Electronics ULR3N Metal Element Inverse Current Sense Resistors offer an inverse 1225 chip format, 100µΩ to 3mΩ value range, and currents up to 170A. The ultra-low ohmic values support high energy efficiency in the end product and the bulk metal technology withstands high current surges for improved reliability. ULR3N Resistors feature an inverse format that keeps current traces wide, avoiding a current crowding hotspot and improving product reliability. Welwyn / TT Electronics ULR3N Inverse Current Sense Resistors are ideal for power supplies, motor control, and DC-DC converters.
