TT Electronics Welwyn OAR-5 Current Sense Resistor, 0.015Ω, 5W, Metal Strip, ±1
High-power 5W current sense resistor, 0.015Ω, ±1% tolerance, metal strip, radial leaded. Operates from -40°C to +125°C.
The TT Electronics / Welwyn OAR-5 series is a through-hole, metal element current sensing resistor with a 5W power rating. Designed for high-power applications, this resistor offers low resistance values from 3mΩ to 50mΩ, making it ideal for accurate current measurement and control in demanding environments.
Engineered for reliability, the OAR-5 series features a temperature coefficient of resistance (TCR) of ±20ppm/°C, ensuring stable performance across a wide temperature range. Its robust construction delivers superior surge performance, while the hot spot is isolated from the PCB material to enhance thermal management and extend component life.
This resistor is capable of withstanding 1000 hours of endurance testing at 25°C and operates effectively from -40°C to +125°C, making it suitable for harsh conditions. The metal strip technology provides excellent current sensing accuracy, and the radial leaded package allows for easy through-hole mounting.
