About the CVDD-500-20S
The CVDD-500-20S is a fixed vacuum capacitor manufactured by Comet / MEIDENSHA. Fixed vacuum capacitor with 500 pF and 20 kV DC working voltage for high-voltage RF circuits requiring low-loss capacitance.
Key ratings of the CVDD-500-20S include type Fixed, capacitance 500 pF, working voltage dc 20 kV, test voltage 30 kV, max current 70 A RMS and minimum q 6000.
Typical applications are high-voltage RF matching, klystron input networks, particle accelerator cavities and high-power pulsed RF systems. Notable features: 500 pF at 20 kV, high voltage specification, 70 A current capability and extra-low loss Q>6000.
Fixed vacuum capacitors use vacuum as the dielectric, which gives extremely low losses, high current capability and stable capacitance at high RF voltage. They are used in RF tank circuits, broadcast transmitters, induction heating and plasma equipment alongside power grid tubes.
