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.
