The datasheet details the 3M™ Three Wall Header 3000 Series connectors, which are primarily used for establishing reliable connections in various applications. Each connector is equipped with features designed for high performance and ease of use.
Product Design Features:
The datasheet highlights the connectors’ latch/ejector mechanisms, stating they come in straight and right-angle configurations. Integrated features include a polarizing key or preferred bump polarization and ejector grounding holes for securing the header to a three-wall shroud, the latter enhancing design flexibility. The connectors are compatible with “no lead” soldering operations and suitable for reflow soldering using “paste in hole” techniques.
Physical Specifications:
The insulators of these headers are constructed from glass-filled polyester (PCT) and possess a UL94V-0 flammability rating with a black coloration. Contacts are made of a copper alloy with an under plating of nickel (2.54µm), and the wipping area has a plating thickness of 30µ” (0.76µm) average gold or 200µ” (5.08µm) tin-lead or matte tin. Markings include the 3M logo, part identification number, and orientation triangle.
Electrical Specifications:
The current rating varies from 5.0A with 9 contacts powered to 0.75A when all contacts are powered. The insulating resistance exceeds 1 x 10^8Ω at 500 VDC, and the series can withstand a voltage of 1000V RMS at sea level. These ratings are applicable under specific operational conditions such as EIA-364-070 Method 2 with a temperature rise constraint of 30°C.
Environmental Performance:
The series is rated for operating temperatures spanning from -55°C to 105°C and has a processing rating of 260°C. Additionally, it has a Moisture Sensitivity Level (MSL) per J-STD-020C.
Ordering Information:
For ordering purposes, various plating options are available based on the part number selected. Tail configurations cater to different board thicknesses and include right-angle solder tails and kinked versions for specialized applications.
Additional Details:
The datasheet includes mounting information for both right-angle (using screws or bolts and nuts) and straight versions of the header. Polarizing and orientation details are provided to ensure correct installation. The recommended PCB hole sizes for the kinked tail positions are also specified. Important regulatory compliance information can be found in the accompanying Regulatory Information Appendix (RIA) and on the 3M website.
Schematic Representations and Assistance:
The datasheet contains drawings and dimensional data to assist with design integration. For technical sales information, contact details including a phone number are provided. The release and revision dates confirm the most recent updates to the document, ensuring that users have access to the current specifications.
