What are the key features of TFM-139-12-H-D-A-P-TR?
- 78-position dual-row layout at 0.050 inch (1.27 mm) pitch for high pin-density board-to-board signal routing
- Horizontal (H) tail termination allows low-profile SMT attachment while post (P) anchors provide mechanical strain relief on the PCB
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place assembly per EIA-481 standards
What is TFM-139-12-H-D-A-P-TR used for?
The TFM-139-12-H-D-A-P-TR is suited for dense multi-signal interconnects in embedded computing modules, FPGAs, and rugged industrial boards where 78 lines must be routed across adjacent PCBs within a tight footprint. Its horizontal tail with post anchoring maintains solder joint integrity under vibration and repeated thermal cycling common in aerospace and defense equipment. The tape-and-reel format streamlines automated assembly for medium to high production volumes.

Frequently Asked Questions
How many signal positions does the TFM-139-12-H-D-A-P-TR support, and what row configuration does it use?
The TFM-139-12-H-D-A-P-TR provides 78 total positions arranged in a dual-row (2 x 39) configuration at a 0.050 inch (1.27 mm) contact pitch. This density makes it suitable for parallel bus and multi-channel signal applications on mezzanine and daughter-card PCB assemblies requiring many I/O lines in a compact connector footprint.
How does the horizontal tail style of the TFM-139-12-H-D-A-P-TR differ from a vertical tail, and which PCB layout benefits most?
The horizontal (H) tail style routes solder terminations parallel to the PCB plane, keeping the connector profile below 3 mm above the board surface compared to vertical tails that extend perpendicular and increase height. This makes the TFM-139-12-H-D-A-P-TR ideal for tight-stacking mezzanine assemblies and enclosures with less than 5 mm of vertical clearance between boards.
What role do the post (P) anchors play in the TFM-139-12-H-D-A-P-TR during high-vibration operation?
The post (P) anchors on the TFM-139-12-H-D-A-P-TR are press-fit or soldered into dedicated PCB holes adjacent to the signal pads, distributing mating and unmating forces across a wider PCB area. This mechanical strain relief protects 78 SMT solder joints from fatigue cracking under vibration levels typical of rail, automotive, or aerospace environments where shock loads can exceed 10 G.
