What are the key features of TSM-109-03-STL-DH-A-P-TR?
- 18-position 0.100 inch (2.54 mm) pitch surface mount terminal strip with straddle mount (STL) configuration for stable PCB edge placement without additional mechanical hardware
- Dual-height (DH) contact variant provides extra clearance above the PCB for adjacent component routing or cable management in height-constrained assemblies
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly with consistent placement accuracy across high-volume production runs
What is TSM-109-03-STL-DH-A-P-TR used for?
The TSM-109-03-STL-DH-A-P-TR is suited for board-edge signal distribution in industrial controllers, embedded computing systems, and test equipment where the straddle mount design straddles the PCB edge to provide a secure 18-position interconnect point at 0.100 inch pitch. The dual-height feature accommodates taller adjacent components and facilitates cable routing over the connector body in compact enclosures. Tape-and-reel packaging simplifies integration into automated SMT lines for consistent high-volume assembly.

Frequently Asked Questions
What does the STL suffix mean in TSM-109-03-STL-DH-A-P-TR and how does it mount to the PCB?
STL stands for straddle mount, meaning the connector body straddles the edge of the PCB with contacts on both sides of the board. This configuration mechanically locks the 18-position 0.100 inch pitch terminal strip to the board edge, eliminating the need for additional retaining hardware while providing a robust surface mount interconnect point.
How does the dual-height (DH) option in TSM-109-03-STL-DH-A-P-TR benefit layouts with tall adjacent components?
The DH (dual-height) contact raises the connector's effective height above the PCB surface by several millimeters compared to the standard height version, creating clearance for adjacent components such as capacitors, inductors, or heat sinks that exceed standard component heights near the 18-position 0.100 inch pitch terminal strip footprint.
When is TSM-109-03-STL-DH-A-P-TR preferred over TSM-109-01-H-DH-A-P-TR for a 0.100 inch pitch 18-position design?
The STL (straddle mount) variant is preferred when the designer needs mechanical stability at the PCB board edge without drilling through-holes, whereas the standard H (horizontal) variant is used for surface placement away from the board edge. Both offer 18 positions at 0.100 inch pitch with dual-height contacts, but the straddle mount version provides superior pull-off resistance at the board perimeter in applications subject to vibration or cable pull forces.
What current and voltage ratings apply to the TSM-series 0.100 inch terminal strip in the TSM-109-03-STL-DH-A-P-TR?
SAMTEC TSM-series 0.100 inch pitch terminal strips are typically rated at up to 3 A per contact and 250 V AC/DC, supporting signal and low-power distribution across all 18 positions. This rating makes the straddle mount dual-height version suitable for 5 V, 12 V, and 24 V industrial and computing bus connections along the board edge.
