Key Features
- 16-position dual-row SMT terminal strip with 0.100-inch (2.54 mm) pitch, compatible with standard 2.54 mm grid PCB layouts for easy routing
- Top-load (TL) dual-height (DH) contact design provides increased stand-off height for improved board clearance and enhanced solder joint inspection
- Tape-and-reel (TR) packaging with gold-plated (A) contacts enables high-speed automated pick-and-place assembly with superior contact reliability
Applications
The TSM-108-04-TL-DH-A-P-TR is used in compact embedded systems, industrial I/O modules, and development board expansion headers where a low-profile 16-position dual-row SMT connector with precise contact alignment is required. Its gold-plated contacts ensure reliable interconnection in high-mating-cycle applications such as removable daughter-card assemblies and field-replaceable module interfaces. The tape-and-reel format makes it suitable for high-volume automated PCB production.

Frequently Asked Questions
What does the TL-DH suffix indicate about the TSM-108-04-TL-DH-A-P-TR contact design?
TL stands for top-load and DH for dual-height, meaning the contacts are inserted from the top of the housing and extend to two distinct height levels above the PCB. This design provides approximately 3 mm to 5 mm additional stand-off height compared to standard SMT terminal strips, improving solder joint accessibility during inspection and rework.
How many positions does the TSM-108-04-TL-DH-A-P-TR provide, and what pitch does it use?
The TSM-108-04-TL-DH-A-P-TR has 16 positions arranged in a dual-row format with 0.100-inch (2.54 mm) pitch between contacts. The 2.54 mm standard pitch aligns with widely used PCB grid systems, allowing straightforward integration with existing 0.1-inch header-compatible board layouts.
When should the gold-plated contact option (A) of the TSM-108-04-TL-DH-A-P-TR be selected over tin-plated alternatives?
Gold-plated contacts are preferred when the connector will undergo more than 100 mating cycles, operate in humid or mildly corrosive environments, or carry low-level signals below 100 mV where even thin oxide layers on tin contacts could increase contact resistance. The A (gold) plating maintains stable contact resistance below 20 mΩ over the connector's rated life.
