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

• Material categorization: for definitions of compliance

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.

Note

• Tolerances unless stated: ± 0.2 mm
