Power Resistor for Mounting onto a Heatsink
Thick Film Technology
FEATURES
• High power rating: 250 W
• High overload capability up to 4 times nominal
power (see energy curve)
• Easy mounting
• Low thermal radiation of the case
• Material categorization: For definitions of compliance
please see
www.vishay.com/doc?99912
Developed for specific applications such as railroad electrical traction, this series can bear short overloads as high as fifteen
times the nominal power. Designed to be mounted onto a heatsink, these power resistors exhibit remarkable characteristics.
