TTElectronics - Welwyn MFR41R0FI Metal Film Resistor

The Welwyn MFR series resistors are axial leaded, professional-grade metal film resistors utilizing thin film technology. They feature a resistance range from 1 ohm to 1 megaohm, available in E24 and E96 decade values. The resistance element is a precisely controlled thin film of metal alloy sputtered onto a high-purity ceramic core, protected by a moisture-resistant, high dielectric strength coating that maintains clear terminations. These resistors are approved to BSCECC 40101-803 and 019 standards, available in 0.5% and 1% tolerances. They have a temperature coefficient (TCR) of ±50ppm/°C, a power rating of 500mW, and operate within a temperature range of -55°C to 155°C. Market demand may result in longer lead times for delivery.
