TE Connectivity (TE) 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
onnections. These features allow the SM Series to withstand the higher temperatures
associated with reflow, vapour phase, or infrared (IR) manufacturing processes without
degradation.
