Type SM Series
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 connections. These features allow the SM Series to withstand the
higher temperatures associated with reflow, vapour phase, or infrared (IR)
manufacturing processes without degradation. Now also available at 7W power
rating.
