specified. Values in brackets
are standard equivalents.
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,
onnections. These features allow the SM Series to withstand the higher temperatures
associated with reflow, vapour phase, or infrared (IR) manufacturing processes without
degradation.
