Product Description
The Samtec TSM-105-03-L-DV is a high-reliability vertical surface mount pin header engineered for demanding board-to-board PCB connection applications. It is part of Samtec’s TSM Series, known for robust performance in industrial, commercial, and automation environments.
This header features 10 male contact pins, organized across 2 parallel rows with a precise 2.54 mm pitch, making it suitable for standard PCB layouts. The contacts are constructed from phosphor bronze and plated with gold, providing excellent electrical conductivity, reduced contact resistance, and superior resistance to environmental stress such as oxidation and corrosion.
The housing is made from black liquid crystal polymer, selected for its dimensional accuracy, mechanical strength, and ability to withstand high temperatures encountered during surface mount solder reflow processes. The unshrouded, open frame design also facilitates visual inspection and probe access during system-level debugging and assembly.
These headers are designed to mount directly on the PCB surface using standard surface mount technology (SMT). The connector supports a maximum current rating of 5.4 A, accommodating both signal and moderate power applications, with a working voltage up to 475 V. Plating is specified as gold (Au), or tin (Sn), applied over a 50 microinch (1.27 micrometer) nickel barrier, extending service life and contact reliability.
Typical operating temperature range is -55°C to +105°C when using tin-plated contacts, and up to +125°C for gold-plated versions, supporting use in both standard and moderately harsh industrial environments. The dual-row, 2.54 mm matrix allows for modular, stackable PCB arrangements in various electronics, test systems, and embedded control platforms.
Common application areas include industrial automation equipment, control panels, measurement instrumentation, embedded computing boards, and signal harnessing within complex assemblies.
