3M™ Mini D Ribbon (MDR) Connectors .050″ Boardmount Thru-Hole Right Angle Receptacle-Shielded 102 Series Datasheet

Category: 3M, Connectors, Electronics

The 3M™ Mini D Ribbon (MDR) Connectors .050″ Boardmount Thru-Hole Right Angle Receptacle-Shielded 102 Series datasheet provides detailed information about the MDR connectors, designed for reliable and stable connections. These connectors are particularly suitable for the IEEE 1284C interface as a 36 contact connector, with contact quantities ranging from 14 to 100 positions.

Physical Specifications

The connectors feature an insulation material made from Glass Reinforced Polyester (PCT) with a UL 94V-0 flammability rating and beige color. Contacts are copper alloy with an underplating of 80 µ” [2.0 µm] Nickel and a wiping area with a minimum of 30 µ” [0.76 µm] Gold. Solder tails have a gold flash over nickel, suitable for SMT processes. The robust body is made from zinc alloy with a nickel plating, and includes a ground lock of copper alloy with tin plating and a gold flash plated tail. The shroud and latch hook are steel with nickel plating, and the connectors are marked with the 3M logo and part number for easy identification.

Electrical Characteristics

Electrically, the connectors can handle a current rating of 1 ampere with an insulation resistance greater than 5 x 10⁸ ohms at 500 Vdc. They are capable of withstanding 500 VRMs for one minute. The connectors are designed to perform in environmental temperatures ranging from -55ºC to +105ºC and can withstand soldering process temperatures up to 260ºC (in accordance with J-STD-020C).

Environmental Compliance and Certification

These connectors are certified by UL under file number E68080 and have a date modified stamp of November 15, 2007. The locally sourced materials are compliant with regulatory standards, detailed further in the Regulatory Information Appendix (RIA).

Configurations and Ordering Information

Diverse configurations provide flexibility for various applications, featuring options for panel and board retention with screw or ground lock mechanisms, accommodating different tail lengths and contact quantities. Special order options are available to cater to unique design requirements. All ordering information, alongside tail length and panel-board retention features, is concisely outlined to ensure correct selection based on the application’s specific needs.

Detailed contact dimensions are provided in both inches [in] and millimeters [mm], ensuring that these connectors meet design specifications. Tail length options and threading for panel mounting further illustrate the versatility of the series.
