Description
JRC CP751C3G205K High-Voltage Oil-Filled Paper Capacitor
2500V DC | 2.0 µF Hermetically Sealed Marine Radar & Transmitter Capacitor | Made in Japan
This item is a 100% genuine original Japan Radio Co., Ltd. (JRC) high-voltage capacitor. As a used surplus component removed from marine radar or communications equipment, it exhibits typical cosmetic surface marks, light scuffs, or paint/label wear consistent with handling and installation. The metal casing, ceramic insulator bushings, and terminal studs remain physically intact and structurally sound. Please note: We sell the exact physical item as shown in the listing photographs. No extra mounting brackets or external wiring leads are included unless explicitly pictured. Please inspect all detailed photos carefully prior to purchase.
Product Overview
The JRC CP751C3G205K is a heavy-duty, hermetically sealed high-voltage oil-filled paper capacitor manufactured in Japan by Japan Radio Co., Ltd. (JRC).
Engineered for high dielectric stability under extreme electrical stress, this 2500V DC, 2.0 µF capacitor is specifically designed for high-voltage DC filtering, energy pulse storage, and magnetron modulator circuits in marine radar systems, RF transmitters, and industrial high-voltage power supplies. Its rugged oil-impregnated paper dielectric housed in a sealed metal container ensures reliable insulation performance in demanding marine environments.
