RW 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 * Great mechanical strength * Fire proof * Environmental performance * Thermal shock strength 0.5 % (100 % h at - 25 C) * Compliant to RoHS directive 2002/95/EC 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. NF F 16101, 10/1988 and 16102, 04/1992: Not applicable (our parts are made of metallic and refractory materials). NF C 93-214. Performances according to NF C 93-214.
