Fusible, Non-Flammable Metal Film Leaded Resistors

FEATURES

• Technology: Metal film

• Overload protection without risk of fire

• Wide range of overload currents (refer Fusing

Characteristics graphs)

• Lead (Pb)-free solder contacts

DESCRIPTION

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

and lead containing soldering processes

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

encapsulant is resistant to all cleaning solvents in

accordance with IEC 60068-2-45.

• Compatible to RoHS directive 2002/95/EC

APPLICATIONS

• Audio

• Video
