Capacitors

RF Power Capacitors > Ceramic Disc > 10kV

Ceramic Power Capacitors can be defined as capacitors suitable for Radio Frequency use with reactive powers greater than 1kVA, rated currents greater than 1A rms and rated voltage greater than 700V

Applications include

  • Radio Broadcast Transmitters
  • Antenna Units
  • Induction and dielectric heating
  • Filter, bypass and coupling circuits in the frequency range 50kHz to 100MHz
