This component falls under the Connectors & Cables category, specifically within Connectors > Headers / Wafers. Headers are fundamental electrical connectors designed to provide a secure and reliable interface for connecting printed circuit boards (PCBs) or other electronic modules. They typically consist of a row or multiple rows of pins that mate with a corresponding socket or receptacle, facilitating signal transmission and power distribution within electronic assemblies. This particular header is engineered for precision and durability, making it suitable for a wide array of demanding applications where space efficiency and signal integrity are paramount.

Key Specifications

The A1276HWV-S-29P-B-H34-E43 header boasts several critical specifications that define its performance and suitability for various electronic designs. The Type is explicitly a “Header,” indicating its function as a male connector component designed to be inserted into a female receptacle. The Pitch is specified as 1.27mm (.050in), which is a crucial dimension representing the center-to-center distance between adjacent contacts. This fine pitch allows for high-density interconnections, enabling more compact PCB designs and miniaturization of electronic devices. The Series, A1276HWV, denotes a specific product family from CJT, often indicating common design characteristics and compatibility within that series. The Contact Finish is “Gold (Au) Plating,” a premium choice that offers excellent conductivity, superior corrosion resistance, and enhanced durability, ensuring reliable electrical contact over extended periods, even in harsh environments. With Number of Rows being “1,” this header is a single-row configuration, simplifying PCB layout and assembly for linear connections. The Contact Material is “Brass,” a widely used alloy in connectors due to its good electrical conductivity, strength, and machinability. The Connector / Cable Type reiterates its identity as a “Header,” reinforcing its role in board-to-board or wire-to-board connections. The Housing / Plastic Material is “Nylon 6T UL94V-0,” a high-performance thermoplastic known for its excellent mechanical strength, thermal stability, and flame retardancy (UL94V-0 rating signifies self-extinguishing properties), ensuring safety and structural integrity. Finally, the Number of Positions / Conductors is “29,” meaning this header provides 29 individual electrical connection points, offering ample connectivity for complex signal and power requirements.
