Key Features
- 8-position dual-row .100" (2.54 mm) pitch surface mount terminal strip with top-left (TL) lead orientation for space-efficient PCB routing
- Solder post (P) tail termination anchors the connector through the PCB, increasing mechanical pull-out strength above 20 N per row
- Gold-plated contacts rated at 3A per pin support mixed power and signal connections in a compact 8-pin dual-row footprint
Applications
The TSM-104-03-TL-DH-P-TR is suited for compact sensor interface boards, relay driver modules, and small embedded controllers requiring an 8-position surface mount terminal strip with enhanced mechanical retention. Its dual-row layout in a .100" pitch footprint accommodates standard IDC cable connections and breadboard-compatible header footprints. The solder post tails provide additional board attachment strength for applications in portable or vibration-prone equipment.

Frequently Asked Questions
What does the TL (top-left) lead style designation mean for the TSM-104-03-TL-DH-P-TR and how does it affect PCB layout?
The TL (top-left) lead style on the TSM-104-03-TL-DH-P-TR positions the solder tails to exit from the top-left orientation of the connector body, which is offset from the standard centered lead exit. This offset tail position shifts the PCB footprint pads by approximately 1 to 2 mm, enabling PCB trace routing to exit the connector field on the left side and reducing trace congestion on the right side of the 8-position dual-row layout.
How many total contacts does the TSM-104-03-TL-DH-P-TR have and what current can the connector handle in total?
The TSM-104-03-TL-DH-P-TR has 8 total contacts in a dual-row DH configuration with 4 contacts per row at .100" (2.54 mm) pitch. Each contact is rated at 3A, giving the connector a total aggregate rated current capacity of 24A when all 8 pins are used for power distribution. In mixed signal-and-power designs, designers typically allocate 2 to 4 pins for power rails and the remainder for signal lines.
For a relay driver board requiring secure connector attachment, how do the solder post tails of TSM-104-03-TL-DH-P-TR compare to surface-only SMT pads?
The solder post (P) tails of the TSM-104-03-TL-DH-P-TR insert into plated through-holes and solder at both the SMT pad on the top side and the through-hole barrel, achieving a combined pull-out force above 20 N versus 8 N to 10 N for surface-only SMT contacts. For relay driver boards that experience vibration from relay switching transients at 50 Hz to 60 Hz, this dual attachment prevents connector rocking and cold joint formation over time.
Does tape-and-reel packaging make TSM-104-03-TL-DH-P-TR suitable for high-speed SMT production lines?
Yes, the -TR suffix confirms tape-and-reel packaging, placing TSM-104-03-TL-DH-P-TR on standard 8 mm or 12 mm SMT tape compatible with pick-and-place equipment from Juki, Panasonic, or Yamaha. Reel quantities of 500 to 1000 pieces per reel enable automated production runs with placement rates above 5000 parts per hour, reducing labor cost compared to tray or cut-tape formats requiring manual feeder loading.
