Power Metal Film Leaded Resistors

FEATURES

• High power in small packages (1 W/0207 size to

3 W/0617 size)

• Different lead materials for different applications

• Defined interruption behaviour

• Lead (Pb)-free solder contacts

• Pure tin plating provides compatibility with lead (Pb)-free

and lead containing soldering processes

DESCRIPTION

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, non-flammable 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 IEC 60068-2-45.

• Compliant to RoHS directive 2002/95/EC

APPLICATIONS

• All general purpose power applications
