What are the key features of TSM-111-04-SM-DH-A-K-TR?
- 22-position dual-row SMT terminal strip with 0.100 inch (2.54 mm) pitch provides reliable signal and power interconnection on compact PCBs
- Tape-and-reel (TR) packaging enables direct use in high-speed pick-and-place machines, supporting high-volume automated assembly
- Dual-height (DH) SMT design accommodates varied board stacking clearances while maintaining a low-profile surface-mount footprint
- Dual-row layout routes 22 signals in a short body length, minimizing footprint impact compared to single-row alternatives of equal pin count
What is TSM-111-04-SM-DH-A-K-TR used for?
TSM-111-04-SM-DH-A-K-TR is suited for IoT sensor modules, industrial embedded controllers, and communication interface boards where a 22-pin 2.54 mm pitch SMT header is needed in tape-and-reel format for volume production. The dual-height feature makes it compatible with stacking scenarios where PCB-to-PCB clearance must be precisely matched, such as in modular radio and compute modules. Its surface-mount reflow compatibility also benefits medical devices and test equipment where through-hole processing is not available.

Frequently Asked Questions
How many positions does TSM-111-04-SM-DH-A-K-TR have, and what pitch spacing does it use for signal routing?
TSM-111-04-SM-DH-A-K-TR has 22 positions in a dual-row layout with 0.100 inch (2.54 mm) pitch. This standard 2.54 mm spacing is directly compatible with most 0.100 inch mating connectors and jumpers, allowing engineers to route 22 independent signals or mixed signal-and-power lines within a compact body that fits standard grid-based PCB layouts without specialized routing rules.
For a high-volume production line, how does the tape-and-reel packaging of TSM-111-04-SM-DH-A-K-TR streamline assembly?
The tape-and-reel (TR) suffix on TSM-111-04-SM-DH-A-K-TR means the connectors are pre-loaded in carrier tape compatible with standard IEC 60286-3 reel sizes for pick-and-place machines. This allows automated feeders to handle the parts continuously during SMT reflow production, eliminating manual tray loading, reducing per-unit placement time, and maintaining consistent orientation for all 22-position connectors across hundreds or thousands of boards per shift.
What does the dual-height (DH) designation mean for TSM-111-04-SM-DH-A-K-TR in PCB stacking applications?
The DH (dual-height) designation indicates that TSM-111-04-SM-DH-A-K-TR is available in a body height that supports a specific board-to-board mating clearance, typically providing an additional 4 mm to 8 mm of stand-off height compared to standard-height versions. This lets designers select the stack height that matches their enclosure or heatsink clearance without switching to a different connector series, reducing BOM complexity in multi-height stacking configurations.
When would TSM-111-04-SM-DH-A-K-TR be preferred over a through-hole 22-pin header in a new PCB design?
TSM-111-04-SM-DH-A-K-TR is preferred over a through-hole 22-pin header when the PCB uses a fully SMT assembly process without wave soldering, when the board is populated on both sides and through-holes would create drill congestion, or when profile height must be minimized. SMT reflow attachment of this 2.54 mm pitch part also avoids the need for selective soldering fixtures and reduces per-board processing steps, lowering assembly cost at volumes above 500 units per month.
