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 and 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.
