TTElectronics---Welwyn MFR4430RFI Metal Film Resistor
The Welwyn MFR series resistors are axial leaded, professional-grade metal film resistors utilizing thin film technology. They offer a resistance range from 1 ohm to 1 megaohm, covering E24 and E96 decade values. 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 options. They feature a temperature coefficient (TCR) of ±50ppm/°C, a power rating of 500mW, 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 are subject to fluctuation. The product is exempt from discounts.
