What are the key features of TFM-125-01-LM-D-A-P-TR?
- 50-position dual-row SMT Tiger Eye strip at 1.27 mm (0.050") pitch with lead-modified (LM) termination for optimized solderability on fine-pitch PCB pads
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place assembly for consistent placement of 50-position 1.27 mm pitch connectors
- Polarization peg (P) prevents mis-oriented mating of the dual-row assembly, critical in high-channel-count signal routing on computing and telecom boards
What is TFM-125-01-LM-D-A-P-TR used for?
The TFM-125-01-LM-D-A-P-TR is designed for high-density signal routing in computing backplanes, telecom switching modules, and network interface cards requiring 50-contact dual-row SMT connectivity at 1.27 mm pitch. The lead-modified termination improves solder joint quality during reflow assembly, while the tape-and-reel format and Tiger Eye contact technology make this strip suitable for high-volume automated production of reliable board-to-board interconnect solutions.

Frequently Asked Questions
How does the lead-modified (LM) termination on the TFM-125-01-LM-D-A-P-TR improve solder joint quality versus standard termination?
The LM (lead-modified) termination on the TFM-125-01-LM-D-A-P-TR features formed leads optimized for surface mount reflow soldering onto fine-pitch PCB pads at 1.27 mm spacing; this modification improves coplanarity and solder wetting across all 50 dual-row positions, reducing the risk of open solder joints compared to standard straight-pin terminations in automated SMT reflow processes.
For a 50-signal high-speed bus on a network switch card, what advantage does the TFM-125-01-LM-D-A-P-TR offer over 2.54 mm pitch connectors?
The TFM-125-01-LM-D-A-P-TR at 1.27 mm (0.050") pitch provides the same 50 dual-row positions in roughly half the PCB footprint of a 2.54 mm pitch equivalent, freeing board area for routing, shielding, or additional components on network switch cards and computing blades where board real estate directly impacts system density and cost.
What volume packaging does the TFM-125-01-LM-D-A-P-TR use and how does this affect assembly line efficiency?
The TR suffix confirms the TFM-125-01-LM-D-A-P-TR is packaged in tape-and-reel format, enabling direct loading into standard pick-and-place feeders for automated assembly of the 50-position 1.27 mm pitch SMT connector without hand-placement; production lines running thousands of boards per shift benefit from reduced cycle time and consistent component orientation compared to tube or tray packaging.
Which SAMTEC connector series is a direct alternative if the TFM-125-01-LM-D-A-P-TR is unavailable and what are the key differences?
The TFM-125-01-F-D-A-P-TR is a close alternative to the TFM-125-01-LM-D-A-P-TR, sharing the same 50-position dual-row 1.27 mm pitch Tiger Eye design and tape-and-reel format but with standard straight-through-hole (F) pin termination rather than lead-modified SMT termination; engineers must verify PCB land pattern compatibility before substituting, as the solder pad geometry and mounting approach differ between the two variants.
