What is Fixed Vacuum Capacitor?

Fixed Vacuum Capacitor is a special electronic component that combines the characteristics of fixed capacitors and vacuum capacitors.

Specifically, fixed vacuum capacitors have a fixed capacitance value, which means that their capacitance will not change after manufacturing, and are suitable for circuits that require stable capacitance performance. At the same time, because it uses vacuum as a medium, vacuum has higher insulation strength and lower dielectric loss than other media (such as air, ceramics, plastics, etc.), so fixed vacuum capacitors can operate at higher voltages and frequencies, and their performance is more stable and reliable.

Fixed vacuum capacitors are widely used in high-frequency circuits, high-voltage circuits, and occasions that require high stability and reliability. Its advantages include high withstand voltage, low loss, long life, and good temperature stability. However, due to its high manufacturing cost and strict process requirements, it is usually only used in specific fields.

When selecting a fixed vacuum capacitor, factors such as capacitance value, rated voltage, frequency characteristics, and environmental conditions need to be considered to ensure that it can meet the needs of the circuit and operate stably. At the same time, due to the particularity of fixed vacuum capacitors, their maintenance and replacement also require professional knowledge and skills.
