Product catalog summary

Overview: The document provides comprehensive details on filter connectors, focusing on MIL-DTL-38999, MIL-DTL-83723, and MIL-C-26482 standards. These connectors are designed to meet military specifications and are compatible with standard non-filtered connectors. Smiths Connectors specializes in EMI/RFI filtering and transient protection solutions.

Design Strategy: Smiths Connectors uses a design strategy based on experience with filter capacitor arrays and diodes, emphasizing system reliability and space efficiency. A protective barrier ensures the durability of the capacitor array.

Modularization: The design groups components into subassemblies like filter and diode modules, allowing for standardized designs that are easy to maintain and upgrade. Modularization enables field replacement of individual modules without affecting other components.

Integration: Components are integrated within connectors to utilize unused space, freeing up board space and reducing crosstalk, while protecting components from environmental damage.

Materials and Finishes: Connectors are made from materials such as aluminum alloy, steel, composite, and high-grade plastic. Contacts are copper alloy with gold plating, and other components include silicon-based elastomer and barium titanate capacitors.

Ordering Information: The document provides a guide for ordering connectors, specifying filter type, series, shell style, mounting options, material/plating, shell size, insert arrangements, contact type, termination, and polarization.

Technical Specifications: Detailed tables provide dimensions and specifications for different series and shell sizes, ensuring compatibility and performance according to military standards.

Specifications and Materials: Key materials include aluminum alloy, steel, composite for shells, high-grade plastic/epoxy for insulators, copper alloy with gold plating for contacts, and silicon-based elastomer for grommets and seals. Brass with silver plating is used for ground planes, barium titanate for capacitors, and ferrite beads for inductors.

Connector Types and Standards: The document references MIL-DTL-83723 and MIL-C-26482 standards, detailing connector types like square flange and jam nut receptacles, emphasizing compatibility with QPL products.

Electrical Characteristics: Detailed electrical characteristics for 'Pi', 'L', and 'C' filter sections include operating temperature range (-55°C to +125°C), voltage rating (100 VDC to 200 VDC), and current rating (15 amps for size 16), along with insertion loss tables and capacitance values.

Performance Data: Products conform to military specifications such as MIL-DTL-38999 and MIL-C-26482, designed for space-grade applications and meeting various military standards.

Contact Termination: Options include crimp/removable, PC tail, solder cup, and compliant press-fit (solderless), with dimensions for different contact sizes and integrated grommets.

Innovations and Testing: Solderless filter connectors with a contact clip for EMI grounding are qualified to MIL-DTL-38999 requirements, with test reports available online.

Overview of Solderless Filter Technology: Solderless filter connectors provide a low resistance path between the capacitor array and connector shell, with a unique seal design for water wash immersion when unmated.

Benefits of Solderless Filter Technology:

RoHS Compliant
No solder design (not potted)
Reworkable filter module assembly
Modular construction
High temperature lead-free solder tolerant
Qualification data available upon request

Filter Adapters: In-Line Filter Adapters allow for easy upgrades to EMI/Transient protection without system modification, available in in-line cable and bulkhead/panel mount versions for various connector series.

Contact Information: Smiths Connectors offers global support with contact points in the Americas, Europe, and Asia. For more information, visit smithsconnectors.com.
