Ceramic Capacitors

We offer a wide variety of tubular ceramic capacitors, which are small in size, lightweight, non-polar, and offer high dielectric strength. These capacitors are fired to produce true monolithic structures, which are impervious to moisture and contamination. 

  • Ideal for multi-pin connector applications
  • Small, lightweight, reliable, high dielectric strength
  • Uniform insertion loss over a broad frequency range
  • Feedthrough and PI type configurations availabl
  • High ratio of capacitance to volume
  • Low inductance, non-polar
  • Impervious to moisture and contamination
  • 0.081" 0.122" diameter
  • Outer terminations feature a nickel barrier and a final metal layer, typically silver.
  • Operating temperatures of –55°C to +125°C are achieved with no voltage de-rating. 
  • High frequency applications
  • EMI filtering and multi-pin connectors
  • Medical devices
  • EMI/RFI suppression filters
  • Commercial applications
  • Defense applications
  • Power supplies
  • Converters
  • Multi-line designs
  • Industrial control process
