Samtec TSW Series Straight Through Hole Pin Header, 3 Contacts, 2.54 mm Pitch, Gold-Plated, Unshrouded, 3 TSW-101-08-G-T-RA

The Samtec TSW-101-08-G-T-RA Pin Header is a precision-engineered board-to-board connector designed for reliable connections in demanding electronics applications. This straight through hole header features three phosphor bronze contact pins arranged in three rows on a standard 2.54 mm pitch, making it ideal for integration into a wide range of prototype and production circuit boards.

Insulation is provided by a high-performance black glass filled polyester housing that offers solid mechanical support, electrical isolation, and high resistance to most chemicals encountered in electronics manufacturing environments. The header's unshrouded design allows for flexible mating with both standard and custom sockets, simplifying the assembly process and enabling easy visual alignment during installation.

Electrical performance is guaranteed through the use of gold-plated contacts (Au or Sn over nickel) that maximize current conduction and minimize the risk of oxidation or corrosion, even in adverse environmental conditions. This header can reliably operate within a temperature range of minus 55 to 125 degrees Celsius with gold contacts installed, ensuring stability for a wide variety of industrial and laboratory environments.

The straight-through hole orientation makes the TSW-101-08-G-T-RA optimal for robust mountings on printed circuit boards, while the solder termination provides secure, lasting connections. It is rated for up to 550 V, supporting safe signal and low-power applications, and is commonly used in industrial control panels, instrumentation, laboratory setups, educational electronics, prototyping, and commercial device manufacturing.

Additional design features include its board-to-board system compatibility, male contact gender, and a voltage rating suitable for most modern PCB assemblies. The parts meet RoHS compliance, enhancing their suitability for environmentally responsible operations:.
