Overview of MOLEX Straight Pin Header
The datasheet provides technical specifications for MOLEX’s straight pin header, which is a component in electrical systems for establishing connections in printed circuit boards (PCBs). The header is designed with dual rows of pins and offers a robust set of options for designers concerning plating and sizing.
Construction Materials
The wafer of the header is constructed from 5% glass-filled polyester, which meets the UL 94V-0 standard, indication of flame retardancy. The pin headers are made from square brass with a tin plating over brass, suggesting good electrical conductivity and anti-corrosion properties.
Plating Options and Specifications
The datasheet mentions several options for plating, which include:
1. A minimum of 300µm tin with 127µm nickel overall.
2. Gold plating in selected areas, with variations in thickness (0.38µm, 0.76µm, or 0.05-0.10µm gold flash) coupled with 300µm tin in selected areas as well as 130µm nickel overall.
These options enable customization to meet specific requirements for connectivity and protection against environmental factors.
Tolerances and Design
The document includes general tolerances and design styles with specifications calling for metrics in millimeters and providing dimensional drawings for precise construction. Furthermore, the suggested PCB hole pattern is outlined, likely to facilitate easy integration into existing board designs.
Additional Information
Additional sheets are referenced which contain more detailed information on the plating (Sheet 2), as well as comprehensive dimensions (Sheets 3-8). Moreover, the recommended PCB thickness to accompany these headers is stated to be 1.50mm.
Proprietary Notice and Revision Details
The datasheet noted is proprietary to MOLEX Incorporated and requires written permission for use. The provided revision and check data imply that there is a history of updates, suggesting that the datasheet reflects an evolved design responsive to industry needs.
In summary, this MOLEX straight pin header is presented as a versatile and reliable choice for PCB design, due to its conformity to standard materials, multiple plating options, and detailed engineering specifications.
