ENGINEERED TO REQUIREMENTOVERVIEW
Designed around
the application.
RCV filtered connectors combine the mechanical interface and EMI filtering into one purpose-built component. We work directly with your team to align capacitance, layout, shell style, termination, and environmental requirements with the real application.
CONNECTOR FAMILIES
Filtered D-Sub and Micro-D connectors.
RCV manufactures EMI-filtered D-Sub and Micro-D connectors alongside our MIL circular filtered connectors. Provide your connector interface and electrical requirements so we can review the configuration for your application.
Filtered D-Sub Connectors
EMI filtering integrated into a D-Sub connector interface, with the contact layout and filtering requirements defined around your equipment.
- Connector part number, shell size, contact arrangement, and mating interface
- Mounting, termination, and available installation space
- Pin-by-pin filtering, operating voltage, current, and signal requirements
- Required attenuation versus frequency and environmental requirements
Filtered Micro-D Connectors
EMI filtering integrated into a Micro-D connector interface for applications with limited connector space. Define the mechanical envelope and circuit requirements together for engineering review.
- Connector part number, contact count, and mating interface
- Mounting, termination, and installation clearances
- Filtered and unfiltered contacts, signal constraints, and electrical ratings
- Attenuation targets, test requirements, and required documentation
Use the Filtered Connector Requirements Worksheet to prepare your contact map and requirements. Include your connector drawing and revision with your request.

EMI/RFI filtering at
the system interface.
A filtered connector places the filter network at the enclosure interface, helping control conducted electromagnetic interference before it reaches sensitive circuitry. RCV engineers custom filtered connector solutions for MIL-DTL-38999 and other circular connector platforms, matching the electrical architecture, contact layout, shell, and termination to the application.
Planar array and Pi tube technologies both support higher-attenuation requirements, while chip-on-flex construction adds flexible component selection—including chip capacitors, TVS diodes, and resistors. Available configurations include C and Pi filter topologies, pin or socket contacts, solder terminations, and PC tails.
What is a filtered connector?
A filtered connector combines a connector interface with integrated EMI/RFI filter components, reducing the need to place every filtering element deeper inside the equipment.
Why filter at the connector interface?
Filtering at the enclosure boundary can help keep unwanted conducted energy from entering or leaving the system and can simplify downstream board-level filtering.
Which filter technologies does RCV offer?
RCV supports planar array, Pi tube, and chip-on-flex connector technologies, selected around attenuation, packaging, component, and program requirements.
Can a filtered connector include transient protection?
Yes. Chip-on-flex configurations can integrate TVS diodes and resistors alongside chip capacitors when the application requires filtering and circuit-protection functions.
