Key Features
- 18-position dual-row layout at 0.100-inch (2.54 mm) pitch for compact yet versatile board interconnects
- Through-mount (TM) posts provide enhanced mechanical stability and board retention beyond standard SMT pads
- 3 A per pin current capacity enabling both signal and auxiliary power routing in a single 18-pin header
- Tape-and-reel (TR) packaging for seamless integration into automated pick-and-place assembly workflows
Applications
The TSM-109-04-TM-DH-P-TR is ideal for compact embedded systems, sensor interface boards, and industrial I/O modules that require reliable 18-position dual-row connections at the standard 2.54 mm pitch. The through-mount post design provides mechanical reinforcement that protects solder joints from lateral stress in handheld or field-deployed equipment. Its surface-mount termination and tape-and-reel format allow integration into high-throughput SMT production lines for consumer electronics, medical devices, and test instrumentation.

Frequently Asked Questions
What distinguishes the through-mount (TM) feature of the TSM-109-04-TM-DH-P-TR from a standard SMT-only header?
The TM designation adds mechanical anchor posts that pass through PCB holes, providing additional retention force beyond the surface-mount solder joints alone. This hybrid design withstands lateral pull forces of 10 N or more, making the 18-position connector suitable for portable equipment and field-service boards that experience mechanical handling stresses.
What current per pin does the TSM-109-04-TM-DH-P-TR support, and at what voltages is it typically operated?
Each of the 18 pins is rated at 3 A continuous current, giving a combined potential of 54 A across all positions. In typical embedded designs, pins operate at 3.3 V, 5 V, or 12 V, supporting both digital signal lines and low-level auxiliary power rails on the same 2.54 mm pitch dual-row connector.
How does the 18-position TSM-109-04-TM-DH-P-TR compare to the 30-position TSM-115 series for sensor interface boards?
The TSM-109-04-TM-DH-P-TR offers 18 positions (9 per row) versus 30 positions in the TSM-115, reducing the occupied PCB footprint by approximately 40% while maintaining the same 3 A per pin rating and 2.54 mm pitch. Designers choose the 18-position variant for sensor boards with fewer I/O channels where board space is tightly constrained.
Is the TSM-109-04-TM-DH-P-TR compatible with standard SMT reflow solder processes given its through-mount posts?
Yes, despite having through-mount mechanical posts, the TSM-109-04-TM-DH-P-TR is designed for surface-mount reflow processing at peak temperatures up to 260°C. The -TR suffix confirms tape-and-reel delivery for automated pick-and-place placement, and the 0.100-inch (2.54 mm) pitch land pattern follows IPC-7351 guidelines for reliable solder joint formation.
