What are the key features of TSM-124-01-F-DH-A-K-TR?
- 48-position single-row SMT terminal strip with 0.100" (2.54 mm) pitch and F flat tail for minimal solder-joint height variation across all 48 contacts during reflow
- Dual-height (DH) body raises the mating interface by approximately 4 mm above the PCB surface, enabling consistent board-to-board spacing in stacked module designs
- Key (K) polarization and tape-and-reel (TR) packaging support high-throughput automated SMT assembly with zero-mis-orientation placement for 48-pin configurations
What is TSM-124-01-F-DH-A-K-TR used for?
The TSM-124-01-F-DH-A-K-TR is designed for single-row, 48-channel SMT interconnects in embedded computing carrier boards, industrial I/O expansion modules, and communication backplane systems operating at standard 0.100" pitch. The dual-height body enables precise board-to-board mating distances in stacked PCB assemblies such as processor-on-module (POM) carrier configurations. Tape-and-reel packaging ensures efficient automated assembly in production environments, while the key alignment prevents mis-mating in field-installed modules handling 48 signal or mixed power channels.

Frequently Asked Questions
How does the F flat tail termination of TSM-124-01-F-DH-A-K-TR differ from standard gull-wing SMT tails, and what soldering benefit does it provide?
The F flat tail lies flush and flat against the PCB pad without the curved gull-wing geometry, providing a more uniform contact area across all 48 positions of the TSM-124-01-F-DH-A-K-TR. This flatter profile reduces coplanarity variation to under 0.1 mm, improving solder joint consistency during reflow at standard lead-free temperatures up to 260°C and reducing the risk of open joints in long, 48-pin single-row footprints.
For a processor-on-module carrier board with fixed board-to-board spacing, how does the DH body height of TSM-124-01-F-DH-A-K-TR constrain mechanical design?
The dual-height (DH) body of the TSM-124-01-F-DH-A-K-TR elevates the mating interface approximately 4 mm above the PCB surface, which sets the minimum board-to-board gap in a stacked assembly. Designers must ensure that the mating receptacle on the opposing PCB matches this 4 mm standoff height. For compute module standards such as SMARC or COM Express, verifying this dimension against the mechanical specification ensures the 48-position interface aligns correctly within the defined form factor.
When is TSM-124-01-F-DH-A-K-TR a better procurement choice than TSM-124-03-SM-DH-A-K-TR for the same 48-position requirement?
TSM-124-01-F-DH-A-K-TR uses a single-row F flat tail layout, which occupies a narrower PCB strip and is suited when signal routing can be accommodated in a single line of 48 contacts at 0.100" pitch. TSM-124-03-SM-DH-A-K-TR uses a surface-mount tail with a different body style and may offer a shorter connector body per position. If PCB width is the limiting constraint and a single-row footprint fits the layout, TSM-124-01-F-DH-A-K-TR is the better choice.
