TTElectronics - Welwyn MFR4100RFI Metal Film Resistors

The Welwyn MFR series resistors are axial leaded, professional-grade metal film resistors utilizing thin film technology. They feature a resistance range spanning from 1 ohm to 1 megohm, with E24 and E96 series values. The resistive 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 ensures clear terminations. These resistors are approved to BSCECC 40101-803 and 019 standards, available in 0.5% and 1% tolerance, with a temperature coefficient of ±50ppm/°C. They have a power rating of 500mW and operate within a temperature range of -55°C to 155°C. Due to high market demand, lead times may be extended, and delivery dates are subject to fluctuation. The product is sold without discounts.
