Power Metal Film Leaded Resistors

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

and cleaning solvents. The encapsulation is resistant to all

cleaning solvents in accordance with IEC 60068-2-45.

FEATURES

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

3 W/0617 size)

• Different lead materials for different

applications

• Defined interruption behaviour

• Technology: Metal film

• AEC-Q200 qualified (PR01 and PR02)

• Lead (Pb)-free solder contacts

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

and lead containing soldering processes

• Material categorization: For definitions of compliance

please see www.vishay.com/doc?99912

APPLICATIONS

• All general purpose power applications



Notes

• R value is measured with probe distance of 24 mm ± 1 mm using 4-terminal method.

(1)

1 % tolerance is available for R

-range from 1 R upwards.

(2)

Ohmic values (other than resistance range) are available on request.
