TTElectronics - Welwyn MFR45K6FI metal film resistor

The Welwyn MFR series resistors are professional-grade, axial leaded metal film resistors constructed using thin film technology. They cover a resistance range from 1 ohm to 1 megaohm, with decimal tolerance options of 0.5% and 1%. 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 keeps terminations clear. These resistors are approved to BSCECC 40101-803 and 019 standards, feature a temperature coefficient of ±50ppm/°C, and have a power rating of 500mW. They are suitable for operating temperatures from -55°C to 155°C. Due to high market demand, lead times may be extended, and delivery dates can fluctuate. The product is exempt from discounts.
