EMI Filter Audio Connectors

APITech has modified the standard MIL-DTL-55116 connectors that are used in 60 volt/0.5 amp audio frequency circuits to provide effective EMI filtering. This EMI filter audio connector is waterproof and polarized, five or six pin electrical plugs/receptacles and can be designed for special and selectively loaded filtering. These custom EMI filter audio connectors meet all the requirements of MIL-STD-810F including sand and dust, salt, fog, high altitude operation, fungus resistance and immersion to 20 meters.

The EMI filter audio connectors also can include ESD (electrostatic discharge) protection up to 8kV direct discharge and 15kV air discharge. Custom designs addressing other discharge requirements are available.

APITech’s circular connector offerings, including EMI filtered versions, 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.
