RW www.vishay.com Vishay Sfernice Fixed Wirewound High Power Vitreous Resistors with Terminal Collars or Bands FEATURES 10 W to 80 W at 25 C NF C 93-214 RB 13 x 70 RB 20 x 117 High power up to 80 W at 25 C High long term stability drift < 2.5 % after 5000 h The RW wirewound power resistors are extremely well Great mechanical strength suited to professional applications, where high power an d Fire proof excellent endurance are required. They meet all requirements of NF C 93-214 specifications and five sizes Environmental performance cover the power range from 10 W to 80 W. Non inductive Thermal shock strength 0.5 % (100 % h at -25 C) types are available, by using the special RWNI winding. For Material categorization: for definitions of compliance higher power or extremely severe conditions of use, see the please see www.vishay.com/doc 99912 RWST series.
