What are the key features of TSM-144-04-S-DV-P-TR?
- 88-position dual-row (2 x 44) configuration at 0.100" (2.54 mm) pitch for high-capacity signal and power distribution
- Gold-plated P contact finish ensures low contact resistance under 30 mΩ and supports over 500 mate-unmate cycles
- DV dual-voltage design allows simultaneous routing of multiple voltage rails through a single connector body
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly for high-volume production
What is TSM-144-04-S-DV-P-TR used for?
The TSM-144-04-S-DV-P-TR is well suited for high-pin-count backplane connections, daughtercard interfaces, and power distribution boards where 88 simultaneous circuits at 0.100" pitch are needed within a single connector. Its dual-voltage DV configuration supports simultaneous 3.3 V and 5 V or 5 V and 12 V rail distribution, common in server backplanes and embedded computing modules. Gold-plated contacts ensure reliable performance in test fixtures and hot-swap card cages subjected to repeated insertion cycles.

Frequently Asked Questions
How many positions does TSM-144-04-S-DV-P-TR provide, and what pitch does it use?
The TSM-144-04-S-DV-P-TR provides 88 total positions arranged in 2 rows of 44 at a 0.100" (2.54 mm) pitch. The total connector length spans approximately 111 mm, making it one of the longest single-body terminal strip options in the TSM series for applications requiring 88 simultaneous signal or mixed-signal/power circuits.
What does the DV designation mean, and how does it help in a multi-rail power distribution board?
The DV (dual voltage) designation indicates the connector is designed to segregate two independent voltage rails within the same body, enabling simultaneous routing of, for example, 3.3 V and 5 V or 5 V and 12 V through adjacent rows. This eliminates the need for two separate connectors on a power distribution board, saving up to 20 mm of PCB edge space and reducing BOM count by 1 connector per board.
For a high-cycle test fixture, why is the gold-plated P contact finish on TSM-144-04-S-DV-P-TR preferred?
The gold P plating maintains contact resistance below 30 mΩ for over 500 insertion-withdrawal cycles, far exceeding the typical 50-cycle rating of tin-plated contacts. In automated test equipment (ATE) and burn-in fixtures that cycle boards 10 to 20 times per day, this translates to over 25 days of continuous operation before contact degradation becomes a concern, reducing maintenance frequency significantly.
How does the 0.100" pitch of TSM-144-04-S-DV-P-TR compare to 0.050" pitch connectors for high-volume backplane designs?
At 0.100" (2.54 mm) pitch, the TSM-144 requires approximately twice the board length of a 0.050" pitch equivalent for the same 88 positions — about 111 mm versus 55 mm. However, the larger pitch provides 2x greater solder pad clearance, reducing the risk of solder bridging during reflow and lowering rework rates on 88-position SMT connectors in high-volume backplane production.
