TTElectronics - Welwyn MFR433KFI Metal Film Resistors

The Welwyn MFR series resistors are axial leaded, professional-grade metal film resistors manufactured using thin film technology. They feature a precisely controlled thin film of metal alloy sputtered onto a high-purity ceramic core, which is protected by a moisture-resistant, high dielectric strength coating. These resistors are available in resistance values from 1 ohm to 1 megaohm, covering E24 and E96 series. Approved to BSCECC 40101-803 and 019 standards, they offer 0.5% and 1% tolerances, with a temperature coefficient of ±50 ppm/°C, a power rating of 0.5W, and operate within -55°C to 155°C.
