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) 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.
