Samtec TMS Series Straight Through Hole Pin Header 3 Contacts 1.27 mm Pitch 1 Row Unshrouded TMS-103-01-G-S

The Samtec TMS-103-01-G-S is a precision-engineered PCB pin header from the TMS Series designed for reliable through-hole mounting applications. This pin header features 3 male contacts spaced at a 1.27 mm pitch and arranged in a single row, providing an efficient interconnection solution for electronic assemblies.

Constructed from phosphor bronze contacts plated with gold, the connector guarantees superior electrical performance. The housing is manufactured using liquid crystal polymer, which enhances durability and ensures stability across the operating temperature range of -55°C to 125°C.

Its unshrouded and straight orientation supports vertical mounting, making it adaptable for various PCB layouts. The termination is by solder, enabling robust mechanical and electrical connections essential for industrial, electronic component manufacturing, and prototyping scenarios.

The contact system uses a .018" (0.46 mm) square post, optimized for consistent mating and long-term reliability. With a 3.05 mm tail pin length and 5.84 mm mating pin length, this header ensures effective contact engagement for board-to-board connections.

Phosphor bronze contacts with gold plating for excellent conductivity and corrosion resistance. Liquid crystal polymer housing provides strength and thermal stability. Supports currents of up to 5A and operating temperatures from -55°C to 125°C.

Through-hole termination allows secure soldering onto PCBs. Ideal for electronic assembly, manufacturing, and prototyping applications.

Samtec’s TMS Series pin headers are widely used in electronic components, power connectors, and PCB connectors, serving industries such as industrial electronics, consumer electronics, telecommunications, and instrumentation.
