PR01/02/03 Vishay BCcomponents Power Metal Film Resistors FEATURES • High power in small packages • Different lead materials for different applications • Defined interruption behaviour. APPLICATIONS • All general purpose power applications 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 or copper-clad iron are welded to the end-caps. The resistors are coated with a red, nonflammable lacquer which provides electrical, mechanical and climatic protection. This coating is not resistant to aggressive fluxes. The encapsulation is resistant to all cleaning solvents in accordance with “MIL-STD-202E, method 215”, and “IEC 60068-2-45”.
