RWST  
Vishay Sfernice  
Fixed Wirewound High Power Vitreous Resistors  
Electrical Traction Model  
FEATURES  
95 W to 800 W at 25 °C  
NF C 93-214  
RB 25 x 168, RB 30 x 250  
Rugged construction for use in severe environmental  
conditions  
Compliant to RoHS directive 2002/95/EC  
“CS” Type 1 Collars  
The RWST vitreous wirewound high power resistors are known for their excellent reliability which has developed out of the  
Vishay Sfernice experience over several decades in the field of high current applications.  
Extremely severe conditions of use are encountered in electrical traction including repeated overloads. To withstand such  
conditions the new RWST model is extremely rugged and is manufactured to a very carefully monitored process using the best  
materials.  
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.
