TE CONNECTIVITY 1676966-3

SMD Moulded Power Resistor Type SM Series 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.
