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.
