3M Pak 100 4-Wall Header .100″ × .100″ Latch/Ejector, Straight and Right Angle 3000 Series is a product of 3M Company. Its features include: military grade (with 3M's 3518 polarizing key), standard ejector latches, mounting holes for securing header to board, RoHS* compliant, optional polarizing posts, high temperature insulator suitable for “no lead” soldering operations and reflow soldering using “paste in hole” techniques.
The Pak 100 4‑Wall Header is part of 3M's Interconnect Solutions line and is offered in both straight and right‑angle configurations. Two latch/ejector variants are available: the short‑ejector X202 for sockets without strain relief and the long‑ejector X302 for sockets with strain relief.
The datasheet provides full electrical, mechanical and environmental specifications, including insulation resistance, temperature range, current rating, and recommended mounting hardware. It also lists part numbers, pin configurations, and accessories such as polarizing keys and mounting screws.
