6 FAQs about [Vacuum capacitor product knowledge]
What is a vacuum capacitor?
A vacuum capacitor is an electrical part having a low ESR (equivalent series resistance) and an extremely small dielectric loss among many existing capacitors. As such, the allowable current of the capacitor is large at high frequency of 1 MHz to a few 100 MHz, and the capacitor has a very good temperature characteristic.
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.
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.
What is the voltage resistance of a vacuum capacitor?
As the electrode part is insulated by vacuum, the voltage resistance is 3 kVp to 40 kVp. It is ideal for the application requiring the high voltage. The vacuum capacitor is a high performance capacitor in which the electrode part that stores electric charges is arranged in a ceramic vacuum vessel.
Who is vacuum capacitors & VCB?
We have been developing and manufacturing Vacuum Capacitors (VCs) since 1992 as the one and only VC supplier in Japan. In making VCs, we adopt the technologies and know-hows related to Vacuum Interrupter (VIs) that we accumulated as we develop and manufacture VIs and Vacuum Circuit-Breakers (VCBs) for more than half a century.
