Vacuum Capacitor (VC)

The VC is a capacitor with the electrode gap in a vacuum. Fig.1 shows the internal structure of the Meiden VCs. Unlike ceramic capacitors where electric charges are stored by inserting a dielectric substance in the electrode gap, dielectric loss can be eliminated by the effect of a vacuum. It becomes a small and high withstand voltage capacitor

What is a Vacuum Capacitor

What is a Vacuum Capacitor? A capacitor is a passive electrical component that is capable of storing electrical charges. A capacitor consists of two conductive surfaces called electrodes, which are usually placed very close to each other. There is an electrical insulating medium between the electrodes—in the simplest case air.

Lineup of vacuum capacitors | Vacuum capacitors | Meiden

A vacuum capacitor is an electrical part having a low ESR (equivalent series resistance) and an extremely small dielectric loss among many existing capacitors. As such, the allowable current of the capacitor is large at high frequency of 1 MHz to a few 100 MHz, and the capacitor has a very good temperature characteristic. Because the electrode part is in vacuum, there is nearly zero

Vacuum variable capacitor

A vacuum variable capacitor is a variable capacitor which uses a high vacuum as the dielectric instead of air or other insulating material. This allows for a higher voltage rating than an air dielectric [1] using a smaller total volume.

Vacuum variable capacitor

A vacuum variable capacitor is a variable capacitor which uses a high vacuum as the dielectric instead of air or other insulating material. This allows for a higher voltage rating than an air dielectric [1] using a smaller total volume.
