What are the key features of TSM-135-03-TM-DH-A-P-TR?
- 70-position dual-row format at 0.100 inch (2.54 mm) pitch delivers very high signal density for board-to-board stacking
- Mid-mount (TM) tail style positions the connector lower on the PCB, reducing overall assembly height
- Dual-height (DH) design provides a fixed inter-board standoff for mechanical and thermal clearance in stacked assemblies
- Tape-and-reel (TR) packaging ensures seamless integration with high-speed SMT pick-and-place production lines
What is TSM-135-03-TM-DH-A-P-TR used for?
The TSM-135-03-TM-DH-A-P-TR is optimized for very high-density board-to-board interconnect in stacked PCB systems such as FPGA daughter cards, high-speed data acquisition modules, and industrial backplane expansion boards requiring 70 positions at a 0.100 inch pitch. Its mid-mount (TM) tail reduces the installed height of the connector on the board, which is valuable in low-profile chassis with tight vertical clearance between layers. Tape-and-reel packaging supports seamless integration into automated SMT production for medium-to-large quantity builds.

Frequently Asked Questions
How many signal positions does the TSM-135-03-TM-DH-A-P-TR provide and how are they arranged?
The TSM-135-03-TM-DH-A-P-TR provides 70 positions in a dual-row layout with 35 contacts per row at a 0.100 inch (2.54 mm) pitch. This high contact count is well suited for applications requiring simultaneous transmission of multiple parallel data buses, power rails, and control signals between two PCBs in a stacked board-to-board assembly.
What does the mid-mount (TM) tail designation mean for the installed height of the TSM-135-03-TM-DH-A-P-TR on a PCB?
The mid-mount (TM) tail style places the connector's solder tails at an intermediate height along the connector body, resulting in a lower installed profile compared to full-length vertical tails. This reduces the total height of the connector above the PCB surface, which is beneficial in enclosures where vertical clearance between stacked boards is limited to a few millimeters. It enables compact, flat assemblies without sacrificing the 0.100 inch pitch signal density.
Which SAMTEC mating connectors are compatible with the TSM-135-03-TM-DH-A-P-TR for a complete board-to-board stack?
The TSM-135-03-TM-DH-A-P-TR is part of SAMTEC's TSM surface-mount terminal strip family and mates with corresponding SAMTEC TSW or SSW series receptacle headers at a 0.100 inch pitch. For a complete 70-position dual-row board-to-board stack, engineers should select a mating receptacle with a matching dual-height and 35-position-per-row configuration from SAMTEC's catalog, or consult the SAMTEC online configurator to identify compatible mating connectors for the target inter-board spacing.
