What are the key features of TSM-120-03-TL-DH-A-K-TR?
- 40-position dual-row 2.54 mm pitch SMT terminal strip provides 40 individually rated 3 A contacts on a compact PCB footprint
- Tall-lead (TL) variant with through-board solder standoff ensures mechanical anchoring and robust solder joints under vibration in industrial environments
- Tape-and-reel (TR) packaging with gold-plated contacts simplifies automated assembly and guarantees low-resistance mating with SFM socket series
What is TSM-120-03-TL-DH-A-K-TR used for?
The TSM-120-03-TL-DH-A-K-TR is used in backplane systems, industrial control panels, and test fixture motherboards where 40 signals or mixed power-and-signal lines must be routed between stacked boards. The tall-lead profile mechanically reinforces the connector against board flexure and vibration shock in harsh environments. Its 2.54 mm pitch dual-row format is broadly compatible with standard test probe arrays and prototyping sockets used in embedded systems development.

Frequently Asked Questions
What is the per-contact current and voltage rating of TSM-120-03-TL-DH-A-K-TR?
Each of the 40 contacts in TSM-120-03-TL-DH-A-K-TR is rated for 3 A continuous current at up to 250 V AC, providing a cumulative board-transfer capacity of up to 120 A when all contacts carry power, which suits mixed power-distribution and signal-routing backplane designs.
How does the tall-lead (TL) designation affect the soldering and mechanical performance of TSM-120-03-TL-DH-A-K-TR?
The TL suffix indicates an extended lead length that protrudes through the PCB before bending, creating a through-board solder anchor; this increases pull-out strength by approximately 30-50% compared to standard surface-only terminations and reduces joint fatigue in applications subject to 5 G vibration or repeated mating cycles exceeding 100 insertions.
Which SAMTEC socket series mates directly with TSM-120-03-TL-DH-A-K-TR on the daughtercard side?
SAMTEC SFM-120 series sockets in the same 2.54 mm pitch dual-row configuration mate directly with TSM-120-03-TL-DH-A-K-TR; the combined assembly yields a 40-position 2.54 mm stacked interface with a defined mated height and a per-pin rating of 3 A at 250 V for all contacts.
