RF Barrel Capacitor

We have many years’ experience in the design and manufacture of RF barrel capacitors for a wide range of applications. Thanks to our broad selection of materials and our extensive applications expertise our products offer life-long reliability and high performance.

Our RF barrel and doorknob capacitors are made from high quality CLASS 1 ceramic dielectric materials chosen for characteristics including high Q factor (low loss), high dielectric breakdown strength and good capacitance-temperature stability.

As a result, these compact capacitors (available in diameters of 10-30mm) offer high kVA ratings, low levels of self-heating and minimal frequency drift. All our products are made using low self-inductance construction, which allows them to be used at higher frequencies, and are proven robust for long operational life.

RF barrel capacitors are ideal for industrial and high power applications including:

Class 1

  • Radio broadcast transmitters
  • Induction and dielectric heating equipment
  • HF filter, by-pass and coupling and oscillating circuits
  • High power matching tuned circuits
  • Antenna coupling circuits
  • Plasma generators

High quality medical imaging systems (MRI)

Class 2

  • Low power decoupling at high frequency

RF barrel and doorknob capacitors can be produced in standard and bespoke designs with a range of capacitance-voltage combinations, ratings and connections.
