6 FAQs about [Variable Ceramic Vacuum Capacitor]

What is a 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.

What are the different types of vacuum capacitors?

We offer five series of VCs, ranging in capacitance from 1 pF to 6000 pF, with peak voltage tolerance ranging from 3 kVp to 40 kVp. Vacuum capacitors are the optimal choice where high voltage, high current and high frequencies intersect. Variable vacuum capacitors incorporate movable plate electrodes.

Why is VC capacitor a small and high withstand voltage capacitor?

It becomes a small and high withstand voltage capacitor by keeping vacuum insulation. The cur-rent capacity of VCs is therefore, more than 100Arms, and the withstand voltage of VCs is a one-tenth than the atmosphere distance by the vac-uum insulation, so a large current can be supplied in a compact size.

Why are vacuum variable capacitors more expensive?

Vacuum variable capacitors are generally more expensive than air variable capacitors.This is primarily due to their design and the materials used. Although most use copper and glass, some may use other materials such as ceramics and metals such as gold and silver. Vacuum variables also vary in adjustment mechanisms. Vacuum Capacitor Characteristics

What is the difference between vacuum capacitor and alumina ceramic?

Vacuum capacitor has resistance losses and dielectric as heat losses. High purity alumina ceramics exhibit reduced low dielectric losses and is recommended for applications requiring higher power at frequencies over 40MHz. (x100pF) Screws and washer sets commonly used in installation. Installation kits are sold separately.
