Tubular Feed-Thru
Ceramic Capacitors
Spectrum Control Technology Inc. manufactures a wide
variety of solid and multi-layered, non-polar, feed-thru,
tubular ceramic capacitors. These tubular capacitors are
small in size, lightweight, reliable and offer high physical
and dielectric strength. Operating temperatures of -55°C
to + 125°C are achieved with no voltage derating.
Standard termination electrodes for all tubular capacitors
feature a nickel barrier and a final silver termination.
Solid Wall Ceramic Capacitors
These feed-thru capacitors have no internal or buried
electrodes and find their primary usage in low cost
applications. Solid feed-thrus are ideally suited for
by-pass, filtering and decoupling applications.
All of our solid capacitors are fired to produce true
monolithic structures which are impervious to moisture
and contamination.
Multilayered Ceramic Capacitors
Spectrum Control Technology Inc. multi-layered feed-thru
capacitors are designed for applications where source
impedances are high, and sharp or steep attenuation
rise is critical. These capacitors will have uniform inser-
tion loss over a broad frequency range and are ideally
suited for greater filtering at lower frequencies.
Our multi-layered, coaxial tubular capacitors consist
of concentric layers of ceramic formulation and of noble
metal electrodes. This concentric structure yields a low
inductance when compared to conventional wound
capacitors. Our high ratio of capacity-to-volume results
in a significantly smaller size than achieved in solid wall
tubular capacitors.
