Key Features ■ Low Profile Design ■ Available on Tape ■ Very Wide Value Range ■ Ideal for Power Circuitry ■ Available in 2,3 or 5 Watts ■ Flameproof Coating UL94V0 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. |
