Vacuum capacitors are employed in a huge variety of applications that require the creation and management of high power radio frequency energy. They are very reliable, long lasting parts. Those packed in a ceramic casing are especially sturdy. While sturdy, these components can be unforgiving if managed incorrectly.
Vacuum capacitors are really a complex system of individual components manufactured with tight tolerances. All of these capacitors, whether glass or ceramic, must be treated with care. The glass packed units can obviously be broken if dropped or banged on a different surface. If dented in certain locations, the inner plates that are made with tolerances as close as 0.010 inches can be emptied out and the device cannot be repaired. But with appropriate care during installation, vacuum capacitors are exceptionally dependable and are going to have very long life.
A few of the things not to do with these components is to knock, drop, or dent them at all. They are generally round and have a inclination to roll off horizontal tables. Vacuum capacitors should be abandoned in the container that they were sent in, if at all possible, till they are ready to be installed. The components are usually packed to prevent damage. Don’t put capacitors in containers along with different capacitors or other parts where they could bang or rub against other substances as they may crack. If the capacitor you have is gasoline filled, then eliminating the protective sleeve may cause injury if dropped, as the contents are under pressure. High voltage ceramic capacitor should care in the same way.
