What are the key features of TSM-103-03-SM-DH-P-TR?
- 6-position dual-row .100" (2.54 mm) pitch surface mount terminal strip with dedicated SM body for low-profile board mounting
- Solder post (P) tail termination provides both SMT surface attachment and mechanical through-board anchoring for improved pull-out strength
- Tape-and-reel packaging with gold-plated contacts rated at 3A per pin supports automated assembly for volume PCB production
What is TSM-103-03-SM-DH-P-TR used for?
The TSM-103-03-SM-DH-P-TR is designed for compact embedded modules, sensor breakout boards, and communication interface cards that require a low-pin-count surface mount interconnect with enhanced mechanical retention. Its solder post tail design anchors the connector through the PCB, preventing rocking or lifting in high-vibration environments. The dual-row 6-position format suits portable battery-powered devices and industrial IoT nodes where board space is minimal.

Frequently Asked Questions
What is the significance of the SM body designation in TSM-103-03-SM-DH-P-TR compared to a standard TSM body?
The SM (surface mount) body on the TSM-103-03-SM-DH-P-TR is specifically profiled for direct SMT reflow, allowing the connector housing to sit flush on the PCB surface without additional mechanical hardware. This differs from standard TSM body styles that may require standoffs; the SM variant typically has a lower profile of approximately 2 mm above the PCB, fitting space-constrained designs.
How do the solder post tails on TSM-103-03-SM-DH-P-TR improve mechanical reliability in vibration-prone applications?
The solder post (P) tails on the TSM-103-03-SM-DH-P-TR extend into plated through-holes in the PCB, creating a solder joint at both the top SMT pad and the through-hole barrel. This dual anchoring increases pull-out force to over 20 N per contact, making the 6-position connector significantly more resistant to mechanical stress than a surface-only SMT termination in vibration environments rated to 20g.
For which low-pin-count interface designs is the TSM-103-03-SM-DH-P-TR a practical choice over a JST or Molex alternative?
The TSM-103-03-SM-DH-P-TR is preferred over JST or Molex alternatives when the design requires a standard .100" (2.54 mm) pitch footprint that mates with a wide range of off-the-shelf IDC cables, breadboard headers, or Samtec mating receptacles. Its 6-position dual-row layout at 2.54 mm pitch provides greater mechanical tolerance than the 1.5 mm or 2.0 mm pitches common in JST SH or PH connectors, easing manual assembly during prototyping.
What current and voltage limits apply to the TSM-103-03-SM-DH-P-TR and how does this affect signal versus power pin allocation?
Each of the 6 contacts in the TSM-103-03-SM-DH-P-TR is rated at 3A per pin at the maximum continuous current for the contact material. The working voltage is typically 125V AC or DC depending on connector spacing. Designers commonly allocate 2 pins for a 3.3 V or 5 V power rail carrying up to 6A combined, and the remaining 4 pins for digital signal lines, enabling a compact mixed power-and-signal 6-pin connector interface.
