Tubular Ceramic Capacitors


Ceramic Tubular Feed Through Capacitor

Tubular Ceramic Capacitors

API Technologies manufactures a wide variety of tubular ceramic capacitors, which are small in size, lightweight, non-polar and offer high dielectric strength. Operating temperatures of –55°C to +125°C are achieved with no voltage de-rating. All ceramic capacitors are fired to produce true monolithic structures, which are impervious to moisture and contamination. Outer terminations feature a nickel barrier and a final metal layer, typically silver.

We offer many variations of tubular capacitors to fit your custom application:

  • Various OD, ID and length configurations
  • Square tubes for surface mount applications
  • Lapped feed-thru capacitors
  • Custom style capability
