TTElectronics - Welwyn MFR44K7FI Metal Film Resistor

The Welwyn MFR series resistors are axial leaded, professional-grade metal film resistors utilizing thin film technology. Covering resistance from 1 ohm to 1 megaohm within the E24 and E96 series, they feature precise metal alloy thin film sputtered onto high-purity ceramic cores. These resistors are protected by moisture-resistant, high dielectric coatings, ensuring clear terminations. Approved to BSCECC 40101-803 and 019 standards, they offer 0.5% and 1% tolerances, with a temperature coefficient of ±50ppm/°C. Rated at 500mW, they operate from -55°C to 155°C, ideal for precise applications, with lead times varying due to market demand.
