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. ...

Vacuum Capacitor Characteristics and Applications
Vacuum Capacitor Characteristics and Applications. 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 using a smaller total volume. There are several different designs in vacuum variables.
