What are the key features of TFM-143-12-F-D-A-P-TR?
- Tiger Eye dual-beam contacts at 0.050" pitch across 86 positions ensure redundant electrical contact and consistent signal integrity over thousands of mating cycles
- Flush-mount (F) contact variant minimizes protrusion height, enabling very low-profile board-to-board stacking in space-constrained assemblies
- Polarization keying (P) and tape-and-reel (TR) packaging prevent mis-mating and support automated high-volume SMT pick-and-place production
What is TFM-143-12-F-D-A-P-TR used for?
The TFM-143-12-F-D-A-P-TR is engineered for ultra-compact board-to-board and mezzanine card interconnections in high-performance computing, defense electronics, and telecommunications equipment where 86 signals must be routed at 0.050" pitch with the lowest possible mating profile. The flush-mount contact design makes it especially valuable in stacked module assemblies where minimizing the total board-to-board gap is critical for fitting within tight chassis envelopes.

Frequently Asked Questions
How does the flush-mount contact option in TFM-143-12-F-D-A-P-TR reduce board-to-board stack height compared to standard contact variants?
The flush-mount (F) designation means the contacts of TFM-143-12-F-D-A-P-TR sit at or near the connector body surface rather than protruding, reducing the mated stack height by several tenths of a millimeter compared to standard contact profiles at 0.050" pitch. In stacked PCB assemblies with 86 signal connections where the gap between boards must be minimized to fit within a chassis depth of 10 mm or less, this reduction is meaningful for mechanical clearance planning.
For a defense electronics module requiring 86 signal connections, why choose TFM-143-12-F-D-A-P-TR over a single-beam contact connector at the same pitch?
Defense electronics modules operating over a temperature range of -55°C to +125°C and under vibration profiles specified in MIL-STD-810 benefit from the Tiger Eye dual-beam contacts in TFM-143-12-F-D-A-P-TR, where each of the 86 positions maintains two independent contact points. If one beam oxidizes, deflects under vibration, or is contaminated, the second beam sustains the electrical path, which is essential for mission-critical signal buses that cannot tolerate intermittent opens.
When selecting between TFM-143-12-F-D-A-P-TR and TFM-139-12-STL-D-A-P-TR for a compact telecom board, which factors favor the 86-position flush-mount variant?
TFM-143-12-F-D-A-P-TR is preferred when the interface requires exactly 86 positions and the board-to-board gap must be minimized, since the flush-mount contact reduces mating height compared to the through-hole straight-lead variant in TFM-139-12-STL-D-A-P-TR. Conversely, when mechanical pull-out strength through 78 soldered through-holes is more important than minimizing stack height in a vibration environment, TFM-139-12-STL-D-A-P-TR provides stronger mechanical anchoring per position.
