High-frequency amplifiers, e.g. antenna amplifiers, FM- VHF-, UHF-tuners and oscillators are mostly built into metal housings in order to avoid spurious radiaton. For insertion of the current lines into the metal housing STELCO offers ceramic feedthrough capacitors in many different styles.

High-integrated components and electronic circuits are very susceptible to malfunction due to electro-magnetic interference. Therefore more and more comprehensive measures to suppress interference voltages are necessary. An effective method to intercept these interferences is e.g. the application of connectors with feedthrough capacitors styles DEEQ and BEEQ.

The most important properties of the SUMIDA-feedthrough capacitor programme are the following:

  • wide capacitance range
  • low self-inductance
  • high attenuation for frequencies up to 3 GHz
  • extensive style programme
  • smallest dimensions
  • resistibility to voltage impulses
