Power Connectors

APITech's Power Connector is a power filter in a circular connector package that includes integrated common mode and differential mode EMI filtering. These connectors can replace traditional larger EMI box filters or power entry filters with similar performance.

Power connectors can be incorporated into many defense and aerospace applications, including ground communications, radar systems, and power distribution products.

APITech’s filtered EMI connector offerings are fully vertically integrated and manufactured in the USA. Components, such as capacitors and shells, are manufactured by our State College, PA facility, providing our customers with high-quality parts with the industry’s shortest lead times.
