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 using a smaller total volume. However, many dielectrics have higher breakdown field strengths than vacuum: 60-170 MV/m for teflon, 470-670 MV/m for fused silica and 2000 MV/m for diamond, compared w

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.

6 FAQs about [Vacuum capacitor design pictures]
What is a vacuum capacitor?
The most common form is inter-meshed concentric cylinders, which are contained within a glass or ceramic vacuum envelope, similar to an electron tube. A metal bellows is used to maintain a vacuum seal while allowing positional control for the moving parts of the capacitor. Invention NikolaTesla filed a patent in 1896 for a vacuum capacitor.
What is the voltage rating of a vacuum capacitor?
The vacuum capacitor (shown to comparitive scale) also has a voltage rating of 5 kV peak, but is variable from 10 to 1000 pF (100:1 range). It is 77.5 mm in diameter at its widest point, and is 171 mm long excluding the control shaft.
What is the difference between air and vacuum variable capacitors?
Air and vacuum variable capacitors for comparison: The air capacitor shown is variable from 34 to 864 pF (25:1 capacitance range), and has a plate spacing of 1.6 mm giving a voltage rating of 5 kV peak (3.5 kV RMS). The dimensions of the capacitor frame (excluding protruding studs and mounting brackets) are: 260 × 126 × 135 mm.
What is the quality factor of a vacuum capacitor?
Quality Factor (Q) Extremely low losses occur in vacuum capacitors because of the vacuum dielectric,compact construction, and the use of low loss glass or ceramic envelopes as well as copper and precious metal solder construction.
Why is a vacuum capacitor better than other variable capacitors?
When compared to other variable capacitors, vacuum variables tend to be more precise and more stable. This is due to the vacuum itself. Because of the sealed chamber, the dielectric constant remains the same over a wider range of operating conditions.
What is the self-inductance of a vacuum variable capacitor?
The self-inductance of vacuum variable capacitors is typically in the order of 6 to 20nH while that of a fixed capacitor is significantly lower, in the range of 2 to 6nH. For most applications, the self-inductance can be ignored. It becomes a factor only when the ratio of capacitive reactance to inductive reactance is small.
