Characteristics Electrical
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.
