TTElectronics - Welwyn MFR4510RFI Metal Film Resistor

The Welwyn MFR series resistors are axial leaded, professional-grade metal film resistors utilizing thin film technology. They feature a precise thin film alloy resistor element sputtered onto a high-purity ceramic core, coated with a moisture-resistant, high dielectric strength layer to ensure durability and stability. These resistors are available in resistance values from 1 ohm to 1 megaohm, encompassing E24 and E96 decade series. They are approved to BSCECC 40101-803 and 019 standards, with tolerance options of 0.5% and 1%, a temperature coefficient of ±50 ppm/°C, and a power rating of 500 milliwatts. Operating temperature ranges from -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 exempt from discount offers.
