Spectrum Control Expands Filter Connector Express™ Family With Introduction of D-Sub Connectors

BOSTON – June 9, 2026 – Spectrum Control (IMS booth #20050), the leader in controlling the electromagnetic spectrum, introduces D-Sub Filtered Connectors, the newest solution in its Filtered Connector Express™ series at IMS 2026. The D-Sub Filtered Connectors allow design engineers to use an online tool to self-configure custom filtered connectors with per-pin selective loading to reduce size and shorten lead times by 50%.

As design complexity and timelines tighten, engineers need faster, flexible filtering. Spectrum Control’s Filtered Connector Express, including the new D-Sub Filtered Connectors, address this market condition. They enable efficient integration of high-performance electromagnetic interference (EMI) filtering and shielding across a wide range of mechanical and electrical options in a single D-sub connector package. 

By designing application-specific filtering directly into the connector, interference is stopped at the point of entry, for enhanced effectiveness and space-efficiency. In fact, a single Filtered Connector can replace up to 128 discrete filters, significantly reducing system complexity.

Engineers can use Spectrum Control’s web-based tool to select from multiple mechanical configurations. Five shell sizes (9-, 15-, 25-, 37-, and 50-pin) and four terminations (two types of pin-to-PCB, pin-to-solder-cup, and socket-to-solder-cup) can be chosen. Various filter types and capacitance can be selected, as well. Spectrum Control will design the selected high-performance D-Sub Filtered Connectors in only 8 weeks – more than twice as fast as the industry average – with no Non-Recurring Engineering (NRE).

Connector Express – Faster, Integrated Solutions to Reduce Footprint

In addition to the new D-Sub Filtered Connectors, a circular version of Connector Express (MIL-DTL 38999-compatible) is available. Both address space and weight considerations related to modern system board designs. They leverage Spectrum Control’s 50+ years of filtering leadership to develop the advanced approach that integrates high-quality filters at the connector entry point.

Connector Express filtered connectors address modern design considerations in a number of applications:

• Military & aerospace systems
• Industrial process equipment
• Peripheral and terminal equipment
• Cellular base stations
• Graphics workstations
• Medical electronics
