Key Features
- 36 positions in a dual-row (DH) layout at 0.100 inch (2.54 mm) pitch for versatile signal routing
- Low-profile mounting (LM) variant reduces total assembly height over standard surface mount strips
- Tape-and-reel (TR) packaging enables high-speed automated pick-and-place SMT assembly
- Surface mount termination style compatible with lead-free reflow solder profiles
- Dual-row configuration maximizes position density within a compact connector footprint
- P option provides additional polarization or position coding to prevent mis-mating in the field
Applications
TSM-118-03-LM-DH-P-TR is used in embedded computing boards, industrial I/O modules, and test and measurement equipment where 36 signals must be routed through a single low-profile 0.100 inch pitch surface mount connector. Its dual-row design and tape-and-reel packaging make it a practical choice for high-volume PCB assemblies requiring compact, reliable signal interconnect between boards or between a board and a panel.

Frequently Asked Questions
How does the low-profile mounting (LM) variant of TSM-118-03-LM-DH-P-TR reduce overall PCB assembly height compared to a standard TSM strip?
The LM (low-profile mounting) variant of TSM-118-03-LM-DH-P-TR sits closer to the PCB surface than the standard mounting height, reducing the overall connector stack height by several tenths of a millimetre. In space-constrained enclosures or stacked card assemblies where clearance between boards may be as little as 5mm, this reduction in profile is often essential.
With 36 positions at 0.100 inch pitch, what total connector span does TSM-118-03-LM-DH-P-TR occupy on the PCB?
In its dual-row (DH) layout, TSM-118-03-LM-DH-P-TR places 18 positions per row at a 0.100 inch (2.54 mm) pitch, giving a row length of approximately 43 mm. The dual-row footprint allows 36 signals to be routed through a smaller board length compared to a single-row 36-position connector at the same pitch.
Does the P option on TSM-118-03-LM-DH-P-TR prevent incorrect orientation during cable or board mating in production?
Yes. The P option on Samtec TSM-series connectors typically designates an additional polarization peg or keying feature that mechanically prevents a mating connector from being inserted rotated 180 degrees. This is especially valuable on a 36-position dual-row connector where reversing orientation could damage up to 36 signal lines and harm downstream ICs.
How is TSM-118-03-LM-DH-P-TR supplied, and what reflow temperature profile is compatible with its surface mount termination?
TSM-118-03-LM-DH-P-TR is supplied on tape and reel (TR suffix), supporting automated pick-and-place placement at production volumes. Its surface mount termination is compatible with standard lead-free solder reflow processes, including peak temperatures of approximately 260°C, ensuring reliable solder joints consistent with IPC-J-STD-020 moisture sensitivity requirements.
