HEADER ASSEMBLY MOD IV – BREAKAWAY, SINGLE ROW, HIGH TEMP, VERTICAL WITH .025 SQ POSTS

Category: Connectors, Electronics, Te Connectivity

The datasheet details the specifications of a HEADER ASSEMBLY, specifically the MOD IV series, which is a breakaway, single-row header with high temperature tolerance and vertical orientation featuring .025 square posts. This header is designed for printed circuit board (PCB) mounting and includes critical dimensions in inches, necessary for the appropriate spacing of posts and mounting on a PCB.

Dimensions and Design

The header’s dimensions are provided with detailed numerical values for the spacing at 2.54mm (0.100 inches) and other measurements required to ensure proper fitting with corresponding components. Each dimension includes a tolerance specification to guarantee compatibility with a range of manufacturing variations. For example, post tips have a typical measurement with tolerances like 0.64 mm ± 0.03 mm (0.025 inches ± 0.001 inches). The document even instructs the ideal hole size before and after plating, signifying the attention to detail in manufacturing operations.

Material and Plating

The construction materials consist of a housing made from a specific CP compound and posts crafted from a copper alloy. The posting and contact areas’ plating details outline the thickness and type of various layers, including gold, nickel, and tin-lead, to adhere to performance requirements.

Part Number and Customization

The header can be customized to the desired number of positions by breaking the assembly accordingly. Each header variation has its unique part number that links to the number of contact positions it holds. The drawings and notations underscore the importance of understanding the true position tolerance when the header is affixed to the PCB for accurate installation and electrical connectivity.

Applicable Standards

The documentation identifies this product as conforming to specific controlled document standards, implying adherence to predefined quality and consistency benchmarks. References to obsolete parts and streamlining decisions indicate that the document has been updated to reflect current offerings and retire older models.

Additional Information

Additional specifications include recommended PCB mounting dimensions for boards of typical thickness, tolerances in the contact areas for gold and matte finishes, as well as the recommended application-specific specifications. The notes also indicate the intended application environment for the header, which is high temperature, and specify that the diagram is a customer drawing, insinuating a standardized design that aids buyers in identifying their needs.

Note: All numerical data are indicative and reflect measurements taken from the diagram, denoting critical spacing, lengths, diameters, and tolerances crucial for integrations into electronic assemblies.
