Category: 3M, Connectors, Electronics

Summary of 3M Four-Wall Header 3000 Series Latch/Ejector Datasheet

The 3M™ Four-Wall Header 3000 Series datasheet covers headers designed for board-to-board interconnections. These components offer latch/ejector mechanisms, available in straight and right-angle configurations, and are compatible with military applications.

Physical Characteristics

The headers feature insulators made from glass-filled polyester (PCT), flaunting a UL94V-0 flammability rating. The contact material is copper alloy, with an under-plating of 100µ” (2.54µm) nickel and a gold plating over the wiping area. The solder tails come tin-lead or matte tin plated to cater to different soldering requirements. The headers are marked with the 3M logo, part identification number, and an orientation triangle.

Electrical Properties

These headers operate within a current rating specified by EIA standards, with a 5.0A rating for one contact powered, 3.0A for six contacts powered, and a 1.75A for all contacts powered. The maximum temperature rise at the rated current is 30°C, with a 20% derated reference. They have an insulation resistance of over 1 X 10^9 at 500 VDC and can withstand voltages of 1000Vrms at sea level. The UL current and voltage rating stands at 10A for all lines powered and 125V, respectively.

Environmental and Regulatory Compliance

These headers endure extreme temperatures ranging from -55°C to +105°C for the EIA rating, and withstand a processing rating of up to 260°C. Compliance with regulatory requirements includes RoHS and features information for “no lead” soldering operations.

Mounting and Polarization

The datasheet details the mounting hardware requirements such as #4-24 thread-cutting screw for the right-angle version and #2-56 bolt and nut for other versions. Polarization options include a 3M key and optional polarizing posts, providing secure fittings when mated with corresponding components.

Ordering Information and Variants

Headers are customizable, with options for high-temperature black insulators and various plating choices. Different configurations and tail sizes are offered to suit board thickness and applications, including solder or wire-wrap post termination. Notches, keying options, and plating details are mentioned, with part numbers correlating to specific configurations for ordering convenience.
