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”.
