Variable Vacuum Capacitor CKTB500/3.5/57
The CKTB500/3.5/57 is a variable vacuum capacitor designed for high‑power RF circuits. It offers a continuous capacitance adjustment from 3.5 pF to 57 pF while handling 500 W of power. The device uses a vacuum dielectric enclosed in a ceramic envelope with copper electrode conductors. It is listed as a direct cross‑reference to Comet part numbers CV05C‑500W/5 and CVBA‑500/BC/5‑BEA‑L.
The vacuum dielectric provides excellent voltage withstand and a quality factor, typical for 500 W vacuum capacitors. The ceramic housing gives a compact footprint and stabilises capacitance against temperature drift. Typical industry specifications cite a Q‑factor above 150 at the operating frequency range. Standard testing includes insulation resistance above 10 GΩ and leakage current below 0.1 µA at rated voltage.
These capacitors are commonly installed in broadcast transmitters, industrial induction‑heating units, plasma generators and medical RF equipment. OEM manufacturers and system integrators source them for replacement or new designs. Buyers should request the supplier’s minimum order quantity, lead‑time and preferred Incoterms before placing an order.
