Filtered Connectors

Filtered Connectors

Air Electro offers a comprehensive selection of filtered mil spec circular and rectangular connectors—including D38999, M24308 D-subminiature, M83723, and others—designed to protect sensitive electrical equipment from unwanted electromagnetic interference (EMI), radio-frequency interference (RFI), and transient voltage spikes.

Filtering can be accomplished by integrating capacitors, diodes, ceramic planar arrays—or any combination thereof—into a connector’s contacts to achieve the desired attenuation levels. Planar arrays are most commonly used, and provide a lightweight, low profile, and effective means of removing unwanted high frequency noise from an electrical system. Diodes allow a connector to shunt spikes in voltage to the ground in the event of a surge, such as lightning strike. Common filtering types include C, L-C, C-L, and Pi, selected based on the capacitance value desired. All types can be packaged inside inline, piggy-back, dual flange, or custom designed shell configurations to meet the space requirements of every application.

In addition to filtered connectors, Air Electro can provide complete testing and burn-in services to ensure that parts perform as intended, as well as an expansive line of contacts, backshells, and accessories to satisfy all of your interconnect requirements.
