Carbon Composition Resistor

Alternatives for Military, Aerospace, and Space Applications

With the end-of-life (EOL) announcements and subsequent discontinuation of 1/4W and 1/2W carbon composition resistors by major suppliers, finding reliable alternatives for critical applications has become essential. RCD Components offers two exceptional carbon composition resistor alternatives engineered for high-energy pulse handling, current limiting, and surge protection in demanding environments.

RCD’s Recommended High-Performance Alternatives

CFZ Series Carbon Film Resistors

Designed for high voltage, high surge, and pulse applications such as medical defibrillators, utility meters, welding equipment, and strobe lighting. The CFZ series provides excellent stability, superior environmental performance, and high thermal conductivity.

PR and PRM Series Pulse Resistors

Robustly constructed for superior energy pulse absorption exceeding conventional film and wirewound types. Suitable for lightning protection, snubber circuits, in-rush current, capacitor charge scenarios, and other high energy transient applications. Available with RoHS-compliant (Sn) or Military-spec (Sn-Pb) termination finishes.
