Product Overview
The OARS1 - R050FI is a 0.05Ω 2W SMD Current Sense Resistor with copper terminations are welded to resistance alloy strip which is then formed. This resistor has 1% tolerance and the value adjustment is achieved by control of width, without the need for subsequent abrasion or notch trimming. Pb-free termination finish is 96% Sn/4% Ag alloy. The resistor will not burn or emit incandescent particles under any condition of applied temperature or overload. The parts are legend marked with ohmic value and tolerance code.
- Flexible leads for thermal expansion
- Open-air design reduces PCB heating
- Values down to 1mΩ
- Zero-ohm 65A jumper version
