MEIDEN Vacuum Capacitors / VC (Vacuum Capacitors)

Inner Structure of Vacuum Capacitors

Vacuum capacitors offer high-performance characteristics due to the electrode parts for storing electric charges allocated inside the ceramic vacuum container. The ceramic chassis resistant to heat generated while the rated current is carried and the vacuum structure with high insulating performance have established the compact, high-voltage, and high-current vacuum capacitors with high reliability. The loss coefficient is kept very small because the vacuum is the dielectric of the capacitor, the chassis is made of high-insulating and low-loss ceramics, and low-loss electrode materials are used. Vacuum variable capacitors are designed to enable the capacitance to change by the vertical sliding motion of the moving electrode assembly located inside the vacuum container. On the other hand, the structure of vacuum fixed capacitors does not allow the capacitance to change because the electrodes in the container are fixed.
