HLH VERTICAL THRU HOLE HEADER ASSY TIN

Category: Connectors, Electronics, Te Connectivity

Summary of Datasheet

The datasheet details the technical specifications and design of a “HLH VERTICAL THRU HOLE HEADER ASSY TIN,” which seems to be a type of connector for printed circuit boards (PCBs). The datasheet includes a revision history section indicating the most recent revision as A2, per ECR-12-007353 on May 8, 2012, reflecting updates or changes to the original document.

Materials and Plating

The materials mentioned for different parts of the connector include brass for the contacts, high temperature nylon rated UL 94V-0 for the housing, and phosphor bronze for the hold-downs, all in a black color. The plating specifics outline that contacts have a minimum of 2.54um of tin-lead over a minimum of 2.7um of nickel. Similarly, hold-downs have a minimum of 2.54um of tin-lead over 1.27um of nickel. Another plating option is nickel with a minimum of 2.54um matte tin over a minimum of 1.27um of nickel.

Physical Specifications

The datasheet lists various dimensions of the connector’s assembly in millimeters (mm), referencing different part numbers. The preferred PCB thickness for the connector’s application is noted to be 1.57mm. Data points are provided in a tabulated form with references to specific part numbers followed by detailed dimensions of length, width, and other pertinent measures.

Part Numbering and Design

Each connector configuration is identified by a unique part number, such as “3-1445051-2.” There seems to be an array of part numbers that denote different sizes and designs within the same product family, as indicated by the series of numbers and dimension references laid out in a grid-like format.

Documentation and Compliance

It’s noted that the drawing forming the datasheet is a controlled document and must be treated accordingly. The document includes a “CAGE CODE” that signifies a unique identifier provided by the U.S. government to the manufacturer. Also indicated is an application specification “Pro/eNGineFi DRAW” that may reference the software or standards used to generate the engineering drawings.

Dimensional and Viewing Information

Dimensions for the assembly are provided in mm, along with PCB layout information for the component side (front view). The finish of the products and their weights are addressed, albeit without specific figures in the provided excerpt.
