Tyco Electronics CGS introduces a

surface mount power resistor suited to

meet today's circuit design needs. Each

size offers low profile case design with

flexible

tinned

copper

terminations for reliable solder joints.

All styles utilize a fully welded

construction technique, unlike other

designs that rely solely on tinned

termination

connections.

These

features allow the SM Series to

withstand the higher temperatures

associated

with

reflow,

vapour

phase, or infrared (IR) manufacturing

processes without degradation.
