Filtered circular connectors incorporate ceramic capacitors to strip unwanted electromagnetic interference (EMI) or transient voltages from signal lines. This type of connector provides an effective filtering device reducing the amount of real estate required within a product enclosure. A filtered circular connector is most frequently used in Military and Aerospace applications, including communications, missile systems, military vehicles, and engine controls. Design Engineers of electronic systems aim for Electromagnetic Compatibility (EMC) between system modules. They are required to minimize destructive EMI common in these electronics systems. A filtered circular connector can help with that.
There are large varieties of filtered circular connectors. Stainless steel, aluminum, composite shells are ideal for environmental and weight-sensitive aircraft applications. Cadmium, nickel, black nickel-zinc plating connectors are excellent for Military, RoHS, and harsh environments. Custom circular connectors are offered in EMI filtered or unfiltered styles, including military standards: MIL-DTL-55116, -83723, -24308, -26482, and -5015. In addition, connectors for transient survival that meet criteria for RTCA/DO-160, level 4 (1,500 voltage transient) are available.
APITech has been a leader in providing application-specific EMI filtered connector solutions since its founding in 1968. Our brand offers the industry’s most extensive line of connectors designed for high-reliability or demanding environmental applications. At APITech, we know it is rare to find an off-the-shelf connector that completely satisfies environmental, mechanical, and electrical requirements. Our engineering team is ready to modify one of these existing designs or start with a "clean sheet" to ensure your connector satisfies all of these requirements. In addition, we can accommodate your quick-turn schedule for prototyping by adding either planar or tubular capacitor filtering to the rear of a standard connector.
APITech's circular connectors are fully vertically integrated and manufactured in the USA. Components, including ceramic capacitors and shells, are manufactured by the State College, PA facility, providing customers high-quality parts with the industry’s shortest lead times.
