Type SM, SMW series wirewound surface mount molded power resistors are designed 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, vapor phase or infrared (IR) manufacturing processes without degradation.
