Features
- Ideal for multi-pin connector applications
- High ratio of capacitance to volume
- Low inductance, non-polar
- Impervious to moisture and contamination
- -55°C to +125°C operation
Spectrum Control 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 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
