NFR25/25H Vishay BCcomponents Fusible, Non-Flammable Resistors FEATURES • Overload protection without risk of fire • Wide range of overload currents. APPLICATIONS • Audio • Video. A homogeneous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in the resistive layer, tinned connecting wires of electrolytic copper are welded to the end-caps. The resistors are coated with a grey, flame retardant lacquer which provides electrical, mechanical, and climatic protection. The encapsulation is resistant to all cleaning solvents in accordance with “MIL-STD-202E, method 215”, and “IEC 60068-2-45”.
