Product information "Fixed Vacuum Capacitors"

25 to 2,000 pF; 4.5 to 33 kV

Vacuum capacitors for high voltage and high frequency applications offer long, maintenance-free service life and the ability to withstand transients that destroy other types of capacitors. Vacuum assures oxidation-free surfaces and a dielectric that is self-healing when subject to transient over-voltage conditions.

This series of fixed vacuum capacitors offers capacitances of 25 to 2,000 pF, withstanding working voltages at 50/60 Hz in the range of 4.5 to 33 kV. In addition to this working voltage, a value for AC test voltage is quoted in this series’ product specifications. The maximum operating current for vacuum capacitors is limited by temperature rise and working voltage. A current vs. frequency chart is provided for each capacitor.

If none of our standard catalog models meet your needs, our supplier`s engineers are happy to work with you to design a custom solution that meets your specific requirements.

Capacitance Tolerance: Fixed capacitors with a nominal capacitance above 50 pF shall be within ±5%. Capacitors with a nominal capacitance of 50 pF or less shall be within ±10%, or 0.5 pF, whichever is greater.

Testing Standards: All capacitors are factory tested for dielectric strength on a 100% basis prior to shipment, using a low current, high potential source at 60 Hz voltage. Upon customer request, certified test reports will be made available.

Key Features:

  • High Voltage Rating
