What are the key features of TSM-126-03-FM-DH-A-K-TR?
- 52-position dual-row configuration on 0.100 inch (2.54 mm) pitch maximizing signal density in surface mount applications
- Flush-mount (FM) SMT termination profile reduces connector height and improves PCB clearance in low-profile assemblies
- Tape-and-reel (TR) packaging compatible with standard EIA-481 SMT feeders for high-speed automated pick-and-place production
What is TSM-126-03-FM-DH-A-K-TR used for?
The TSM-126-03-FM-DH-A-K-TR is used in high-density board-to-board signal routing for embedded computing modules, FPGA evaluation boards, and communications interface cards requiring 52 contacts on 0.100 inch pitch. Its flush-mount SMT tails reduce the overall mated height, making it suitable for compact enclosures with tight PCB-to-panel clearances. The dual-row layout and tape-and-reel packaging streamline automated assembly for industrial control systems and high-volume telecom hardware.

Frequently Asked Questions
What contact count and pitch does the TSM-126-03-FM-DH-A-K-TR support?
The TSM-126-03-FM-DH-A-K-TR provides 52 contacts arranged in a dual-row format with 0.100 inch (2.54 mm) center-to-center pitch. This high contact density is suitable for applications requiring many I/O lines within a standard through-hole or SMT footprint.
How does the flush-mount termination of the TSM-126-03-FM-DH-A-K-TR differ from standard SMT tails?
The flush-mount (FM) termination sits level with the PCB surface pads, minimizing standoff height compared to gull-wing or J-lead profiles. This allows lower mated stack heights—often below 8 mm—making the connector suitable for slim industrial modules and computing blades with strict height budgets.
Which automation-friendly packaging does the TSM-126-03-FM-DH-A-K-TR use, and how many units fit per reel?
The TR suffix indicates tape-and-reel packaging compliant with EIA-481 carrier tape standards, enabling automated SMT placement at rates exceeding 5,000 parts per hour. Reel quantities typically range from 250 to 1,000 pieces per reel depending on part size, reducing changeover downtime on high-volume lines.
In which scenarios would the TSM-126-03-FM-DH-A-K-TR be preferred over a standard through-hole pin header with 52 positions?
The TSM-126-03-FM-DH-A-K-TR is preferred when the PCB assembly uses full SMT reflow rather than wave solder, or when both sides of the board are populated and through-hole drilling is impractical. Its 0.100 inch pitch maintains compatibility with existing dual-row mating receptacles while eliminating drill holes and reducing board fabrication cost.
