RPH 100
Vishay Sfernice
Power Resistor for Mounting onto a Heatsink
Thick Film Technology
FEATURES
• High power rating
• Low thermal radiation of the case
• Wide ohmic value range
• Easy mounting
• High overload capabilities
• Reduced size and weight
This new style has been developed as an extension to RCH range. Through the use of thick film technology, a non-inductive
solution for power resistors is available which are rated up to 100 W at + 25 °C. The terminations position prevents any risk of an
electrical arc to the heatsink. This resistor series can replace and offer advantages to standard wirewound devices.
