3M™ Four-Wall Header 3000 Series

Category: 3M, Connectors, Electronics

The 3M™ Four-Wall Header 3000 Series is a collection of connectors that feature a latch/ejector mechanism in various configurations, such as straight and right-angle orientations. These components are characterized by their compatibility with military specifications, integrating a 3M 5 N3518 polarizing key and a centerbump for polarization to ensure secure mating of the header to the board. Optional polarizing posts are also available.

The series boasts a high-temperature insulator suitable for “no lead” soldering processes and is conducive to reflow soldering using “paste in hole” techniques. The datasheet specifies the availability of different solder tail options. Additionally, for regulatory information compliance, the datasheet refers to an appendix and the RoHS compliant section on 3M’s website. In case of any conflict, precedence is given to the product specification detailed in the datasheet.

Physical and Material Characteristics: The insulator material consists of glass-filled polyester (PCT) rated UL94V-0 for flammability, featuring a black color. Contacts are made of copper alloy with under-plating of 100 microinches (µ”) [2.54 µm] average nickel. The wiping area is plated with 30 µ” [0.76 µm] average gold, and the solder tails are available in tin-lead or matte tin (reference specific ordering information).

Electrical Properties: The current rating is defined by several configurations: 5.00A when one contact is powered, 3.00A for three contacts, and 1.75A when all contacts are powered, per EIA 364-070 method with a maximum temperature rise of 30°C. The insulation resistance is greater than 1×10^9 ohms at 500 VDC, and there’s a withstand voltage of 1000 Vrms at sea level. The headers have a UL current rating of 1.0A for all lines powered and a voltage rating of 125V.

Environmental Data: The temperature rating ranges from 55°C to 105°C, with a process rating capable of withstanding 260°C for J-standard single pass soldering. The moisture sensitivity level is per J-STD-020C. Ordering information suggests various plating and tail options, including lengths suitable for different thicknesses of boards and the presence of a kinked tail for secure soldering.

The datasheet details the part number configuration guide, including codes that depict plating material, pin configuration, and solder tail options. It concludes with revision and approvals history, indicating the last update being on July 10, 2015, and suggests the use of mounting hardware specific to the right-angle version of the header.

The datasheet is marked with a significant notice that in the presence of any discrepancies, the specifications detailed in the product data take precedence over the datasheet. 3M’s trademark, contact information, and references to its solutions division’s website are also provided, emphasizing 3M’s role as the manufacturer of the header series.
