New Yorker Electronics Releases Miniature 300W Chassis Mount Heat Sink Resistor from RCD

New Resistors are Designed for Medical Equipment, Laser Systems, Pulse Generators and More


November 28, 2018 – New Yorker Electronics has released the RCD Components Miniature 300W Non-Inductive, Low-Profile Chassis Mount Resistors in both the CM300 and CM300L Series.

RCD Components, a global leader in the manufacture of passive components, developed the CM300 and CM300L Series for power Supply manufacturers looking to save space, height and weight. The RCD 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 significantly lower price.

The series is less than half the height of an SOT227 package and quicker and easier to mount. It is essentially vibration-proof and with insulation ratings up to 5KV.

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-inch male quick-connect terminals and the CM300L features flexible insulated leads with a range of customized terminations. Burn-in, military-screening and numerous design modifications including different diameters, lengths, materials, values, markings, lead/Pb terminations and others.

Attached to a suitable air- or water-cooled heat sink, RCD’s CM300 proprietary flame retardant epoxy insulation ensures optimal environmental protection and dielectric strength. Applications for this chassis mount heat sink 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 requirements.
