Vacuum Capacitors

Vacuum variable capacitors are an ideal dielectric that store a higher voltage than air dielectrics while using a smaller total volume. Richardson Electronics offers a wide variety of vacuum capacitors ranging from 12pF to 5,000pF and covering test voltages of 5kV to 60 kV. Select from a full range of fixed, variable, and water-cooled capacitors for use in demanding RF applications, including wafer fabrication, plasma, medical, broadcast, and industrial heating. With over 75 years of experience supplying capacitors to OEM and MRO markets, we are confident that we can find the capacitor needed to meet your industry requirements.
