FILTERED CONNECTOR EXPRESSTM
D-Sub Filtered Connectors
Specify a custom filtered connector to your requirements.
Specs to finished prototypes or production volumes in 8 weeks!
Use the online configurator below to design a custom EMI-filtered D-Sub connector with integrated Pi and C circuit protection.
Choose from five shell sizes, 9, 15, 25, 37, and 50 pin, in straight and right-angle configurations.
Termination options include pin-to-PCB, pin-to-solder-cup, and socket-to-solder-cup.

Product Overview
Spectrum Control has applied its 50 years of experience in managing EMI/EMC to create an expedited approach to building custom connectors for military and aerospace applications. We can now deliver custom high performance D-sub filtered connectors to your specifications in only 8 weeks with no NRE.
-
Configurable connector – with circuits/values for mixed signals in a single d-sub connector package
-
Quick turnaround – for quick prototyping or production units, from specs to finished products in 8 weeks; no NRE
-
Superior EMI filtering – Spectrum Control manufactured custom coaxial tubular capacitors facilitate superior broadband performance, particularly at high frequencies, versus chip on board (COB) and chip in seal versions
-
Soldered construction – for better high-frequency performance over mechanical designs
-
Large capacitance pin-to pin-ratio range – for optimized performance in mixed signal applications in a single package

Quality Assurance
All EMI filtered connectors undergo extensive testing to ensure that all products meet specification requirements. Many tests are performed 100% by computer-controlled test sets, including capacitance, dissipation factor, dielectric withstanding voltage, and Insulation resistance as routine. Others are tested on a sample basis as applicable. Test plans can be configured to specific customer requirements.
Qualification/special testing - Spectrum has a fully qualified test laboratory and can provide additional acceptance testing upon the customer’s request. This could be a one-time qualification exercise or ongoing periodic testing.
