FMW MELF Resistors

Welwyn / TT Electronics Fusible MELF Wirewound (FMW) Resistors are UL-recognised fusible wirewound resistors in SMD MELF format. These resistors feature up to 1.7J withstand fast inrush energies, 1W continuous power rating, and ±200ppm/°C TCR. The FMW MELF resistors consist of a design tailored to minimize fusing times at low power overloads. These resistors value down to 1Ω to support low quiescent power loss goals. Typical applications include power supplies, white goods controllers, building control systems, and cordless product chargers.
