Custom Circular EMI Filtered Connectors
Spectrum Control offers custom circular connectors with EMI filters or unfiltered styles, including military standards. Our filtered compact shell connectors provide an effective EMI filter that reduces the amount of real estate required within a product enclosure. Using our expertise in EMI filter design and manufacturing, we offer planar-style filtered arrays.
This premium line of custom circular mil-spec connectors are completely intermateable with MIL-DTL-38999 Series III.
Spectrum Control’s EMI filtered connector offerings are fully vertically integrated and manufactured in the USA, where components, including ceramic capacitors and shells are produced. This provides our customers with high-quality parts, with the industry’s shortest lead times.
