RPS 500
Vishay Sfernice
Power Resistors for Mounting onto a Heatsink
Thick Film Technology
FEATURES
• High power rating
• High overload capability
• Easy mounting
• Low thermal radiation of the case
This range has been developed specifically for electrical traction applications and is capable of dissipating 500W at +70°C.
The remarkable performance characteristics are evident when used in severe pulse conditions. The copper base allows easy
mounting on the heatsink and provides optimal dissipation conditions.
