Vacuum capacitors are employed in a wide variety of applications that require the creation and management of high power radio frequency power. They are extremely reliable, long lasting parts. While hardy, these components can be unforgiving if managed incorrectly. High voltage ceramic capacitor should care in the same way.
Vacuum capacitors are really a complex system of individual components manufactured with tight tolerances. Every one of these capacitors, whether ceramic or glass, have to be treated with care. Due to the tight tolerances and intricate parts assembly, the ceramic vacuum capacitors can be ruined permanently if dented, dropped, or banged. If dented in some specific areas, the internal plates which are made out of tolerances as close as 0.010 inches may be shorted out and the unit can’t be repaired. But with appropriate maintenance during installation, vacuum capacitors are exceptionally dependable and are going to have very long life.
A few of the things to not do with these units is to knock, drop, or dent them at all. They are usually round and have a inclination to roll off flat tables. Vacuum capacitors must be abandoned in the container they were sent in, if at all possible, till they are ready to be installed. The units are usually packed to avoid damage. Don’t place capacitors in containers with different capacitors or other areas where they can rub or bang against other materials as they may crack. If the capacitor you have is gasoline filled, then eliminating the protective sleeve might cause injury if dropped, as the materials are under pressure.
