EMI Filter & Power Circular Connectors from Spectrum Control

EMI Filter & Power Circular Connectors from Spectrum Control

Spectrum Control offers custom circular connectors in EMI-filtered or unfiltered styles, including military standards. The EMI-filter, compact shell connectors provide an effective filtering device that reduces the amount of real estate required within a product enclosure. Using their expertise in EMI filter design and manufacturing, Spectrum Control offers planar-style filter arrays, available in C and Pi circuits up to 200 nF in most configurations. Other filter circuits, including transient protection, are also available.

Spectrum Control’s EMI-filter connector offerings are fully vertically-integrated and manufactured in the USA. Spectrum Control builds components in-house, including ceramic capacitors and shells, providing customers with high-quality parts.
