Frequently Asked Questions
How many positions and what pitch does TSM-109-04-H-DH-A-K-TR support for board interconnects?
TSM-109-04-H-DH-A-K-TR is an 18-position dual-row connector with a standard 2.54mm (0.100") pitch. The dual-row layout provides 9 pins per row, making it suitable for carrying both power and signal lines in a compact footprint. This 0.100" grid spacing is compatible with most standard 2.54mm mating receptacles and breadboards.
What does the H and DH designation indicate about the post height of TSM-109-04-H-DH-A-K-TR?
The H and DH suffixes in TSM-109-04-H-DH-A-K-TR indicate a high-profile post design with approximately 4mm insulator height above the PCB. This taller post height accommodates connectors used in stacked board applications or where wire leads need extra clearance. It ensures reliable mating engagement even when slight board-to-board parallelism variation exists.
Is TSM-109-04-H-DH-A-K-TR supplied in tape-and-reel format for automated assembly?
Yes, the TR suffix confirms TSM-109-04-H-DH-A-K-TR is packaged on tape-and-reel for automated pick-and-place SMT assembly. This format is standard for high-volume PCB production where manual handling of 18-position headers would be impractical. Reel quantities typically hold hundreds of connectors, reducing changeover time on assembly lines.
What applications benefit most from the SAMTEC TSM-109-04-H-DH-A-K-TR terminal strip?
TSM-109-04-H-DH-A-K-TR is ideal for backplane signal routing, embedded daughterboard interfaces, and modular industrial I/O panels that require an 18-pin 2.54mm connector with reliable solder-joint integrity. Its dual-row 9×2 layout supports mixed signal and power distribution on boards where space allows a 2.54mm footprint, covering applications from test fixtures to communication modules.
