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.
