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 suited to professional applications, where high power and excellent endurance are required. They meet all requirements of NF C 93-214 specifications and five sizes cover the power range from 10 W to 80 W. Non inductive types are available, by using the special RWNI winding. For higher power or extremely severe conditions of use, see the RWST series. * Great mechanical strength * Fire proof * Environmental performance * Thermal shock strength 0.5 % (100 % h at -25 C) * Material categorization: for definitions of compliance please see www.vishay.com/doc?99912 NF F 16101, 10/1988 and 16102, 04/1992: Not applicable (our parts are made of metallic and refractory materials).
