Power Resistor for Mounting onto a Heatsink
Thick Film Technology
FEATURES
• High power rating: 500 W
• High overload capability up to 2 times rated
Power (see energy curve
• Heatsink mounting
• Low thermal radiation of the case
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
This range has been developed specifically for electrical traction applications and is capable of dissipating 500 W 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.
