IRC LRF3W Series Surface Mount Chip Resistor

IRC's 3W surface mount chip resistors are offered in a 1225 package size. The chip resistors feature low resistance and high power capabilities. The LRF3W Series chip resistor features a resistance range from 0.002Ω to 0.100Ω, with absolute tolerances of ±1%, ±2%, ±5% and ±10%. Power dissipation is up to 3W at 70°C, with TCR as low as ±100ppm/°C. Operating temperature ranges from -55°C to +150°C. The chip resistors feature leach-resistant wrap-around terminations with either tin/lead or lead free matte tin over nickel plating.

Because of its high power rating in the space-saving package, the LRF3W Series resistor is ideal for high current-sensing applications including fuel-gauging and over-current detection, AC/DC power supplies and VRMs, motorized seats, power windows, seat heaters and automotive fuel pump collision cut-off.
