TTElectronics - Welwyn MFR482RFI Metal Film Resistor

The Welwyn MFR series resistors are axial leaded, professional-grade metal film resistors utilizing thin film technology. They cover a resistance range from 1 ohm to 1 megaohm, including E24 and E96 value series. 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 ensures clear terminations. These resistors are approved to BSCECC 40101-803 and 019 standards, available in 0.5% and 1% tolerance levels, with a temperature coefficient (TCR) of ±50ppm/°C. They are rated for 500mW power dissipation and operate effectively within a temperature range of -55°C to 155°C. Due to high market demand, lead times may be extended, and delivery dates could fluctuate. These products are exempt from discounts.
