Capacitor
Spectrum Control

Inside every EMI filter is a ceramic feed-through capacitor. Spectrum has engineered a line of ceramic capacitors designed to provide solutions to a wide range of filtering applications. These ceramic capacitors are ideal for EMI/RFI suppression filters, medical implantable devices, commercial and military applications, power supplies and converters.

Tubular feed-through (FT) and Pi (π) are small in size, lightweight, non-polar and offer high dielectric strength. With a high ratio of capacitance to volume, all capacitors are fired to produce true monolithic structures impervious to moisture and contamination. We offer many variations of tubular capacitors to fit any custom application, including: various OD, ID and length configurations; square tubes for surface mount applications; and lapped feed-through capacitors.

Discoidal feed-through capacitors are the building blocks of the EMI filter industry. Due to their low inductance construction, these capacitors perform extremely well in high frequency applications. In addition, these low inductance, non-polar discoidal capacitors are ideal for by-pass and filtering applications.

Spectrum's planar capacitors are quickly becoming the new standard in filtered connectors used in EMI suppression applications. Various custom and industry standard geometries are available and our designs can incorporate multiple capacitance values, feed-through holes and ground holes.
