This specific component falls under the Connectors & Cables category, more precisely Headers / Wafers, and is designed for robust and reliable electrical connections in a wide array of electronic circuits. Headers are fundamental components in PCB (Printed Circuit Board) design, serving as an interface for connecting various modules, components, or external cables. They are crucial for prototyping, production, and field servicing, allowing for modularity and ease of assembly or disassembly. The A1276HWV-S-2P-A-H20-W18-T, with its precise specifications, ensures stable signal transmission and power delivery in demanding applications.

Key Specifications

This header connector boasts several critical attributes that define its performance and suitability for various applications. The ‘Type’ is explicitly a ‘Header’, indicating its function as a male connector designed to mate with a corresponding female receptacle. The ‘Pitch’ is specified as ‘1.27mm (.050in)’, which is a standard fine-pitch dimension, allowing for compact board designs and higher density interconnections compared to larger pitch connectors. This small pitch is essential for miniaturized electronic devices. The ‘Series’ is ‘A1276HWV’, identifying it as part of a specific product line from CJT, which typically signifies a consistent design philosophy and compatibility within that series. The ‘Contact Finish’ is ‘Gold (Au) Plating’, a premium choice known for its excellent conductivity, superior corrosion resistance, and long-term reliability, especially in environments where oxidation could degrade performance. The ‘Number of Rows’ is ‘1’, meaning it is a single-row header, simplifying board layout for certain applications. The ‘Contact Material’ is ‘Brass’, a commonly used alloy in connectors due to its good electrical conductivity, mechanical strength, and cost-effectiveness. The ‘Connector / Cable Type’ reiterates ‘Header’, confirming its form factor. The ‘Housing / Plastic Material’ is ‘Nylon 6T UL94V-0’, a high-performance thermoplastic known for its excellent mechanical strength, high temperature resistance, and a UL94V-0 flammability rating, indicating it is self-extinguishing and safe for use in various electronic devices. Finally, the ‘Number of Positions / Conductors’ is ‘2’, meaning this header provides two individual electrical connection points, suitable for simple signal or power connections.

Features and Benefits

• Compact Design: The 1.27mm pitch allows for high-density interconnections, enabling smaller PCB footprints and more compact electronic devices, which is crucial for modern miniaturized electronics.
