RCD Introduces Miniature 300W Heat-Sink Resistors​

Manchester, New Hampshire (USA) – RCD,a global leader in the manufacture of passive components, announced today the introduction of their CM300 series of chassis mount resistors.

“Our CM300 was developed for a manufacturer of power supplies that wanted to save space, height and weight. Our CM300 is rated up to 300 Watts and is less than 1/10 the size and weight of a conventional RE80 250 Watt chassis mount resistor at a significant cost savings. It is also less than ½ the height of an SOT227 package, is quicker and easier to mount, and 30% lighter. The product is essentially vibration-proof and is available with insulation ratings up to 5KV. It’s clearly the answer to some of the size and weight issues faced by many design engineers.”

RCD’s CM300 series is non-inductive and features a wide range of resistance values (0.1 ohm to 1 Meg). The CM300 model features .187” male quick-connect terminals and the CM300L features flexible insulated leads with a range of customized terminations. Burn-in and Military-screening and numerous design modifications are available.

Applications include automotive, medical equipment, high voltage power supplies, pulse generators, X-Ray equipment, RF generators, laser systems, EMI/RFI filters, snubber circuits, bypass and coupling circuits and other high voltage or power application.

Volume production is available immediately. Contact or for more details.
