Spectrum Control offers custom EMI filtered circular connectors, including military standards. Our EMI filter compact shell connectors provide an effective filtering device 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 filter arrays, available in C and Pi circuits up to 200nF in most configurations. Other filter circuits, including transient protection, are available.

• Soldered construction for better high-frequency performance over mechanical designs
• Large planar capacitance pin-to-pin ratio range to provide power and signal filtering in a single package
• EMI filter connectors with insulated and ground line options
• Predictable line-to-line isolation for segregated line IL performance
• Military Specifications: MIL-DTL-38999, MIL-DTL-55116, MIL-DTL-83723, MIL-DTL-26482, MIL-DTL-5015
• Bayonet style available
