ULR3N metal element inverse chip resistors are designed in inverse format with terminations on the long sides, which gives good resistance to thermal and board flex stresses and supports the use of wide current traces. Wich a precision of down to 1% tolearance and 100ppm/°C, ULR3N offers a choice of 15 ohmic values from 100uOhms to 3mOhms. Rated at 3W, this product is suitable for sensing currents at levels up to 170A, and is therefore in most cases restricted only by the current carrying capacity of the PCB traces. The bulk metal technology used for these parts gives high energy capacity for current surge events, compared to film or foil alternative technologies.
