What are the key features of TFM-147-22-STL-D-A-P-TR?
- 94-position dual-row .050" (1.27 mm) pitch Tiger Eye terminal strip optimized for high-density SMT board-to-board signal connections
- Long-tail (STL) SMT termination variant provides extended solder joint reach for improved mechanical robustness on thick or warped PCBs
- Alignment post (A) and polarization (P) features prevent mismatement and support precise automated pick-and-place placement during production
What is TFM-147-22-STL-D-A-P-TR used for?
The TFM-147-22-STL-D-A-P-TR is used in high-reliability board-to-board applications in aerospace avionics, defense electronics, and high-performance computing platforms where 94 pins at .050" pitch provide maximum signal density in a constrained footprint. Its long-tail SMT termination improves solder joint strength in thermally stressed environments such as ruggedized industrial controllers and embedded radar modules. The built-in alignment post and polarization guard against assembly errors in high-volume automated manufacturing lines.

Frequently Asked Questions
What is the total pin count and contact pitch of the TFM-147-22-STL-D-A-P-TR terminal strip?
The TFM-147-22-STL-D-A-P-TR provides 94 positions arranged in 2 rows at a .050" (1.27 mm) pitch, allowing designers to route a large number of signals in approximately half the PCB area required by traditional 2.54 mm pitch connectors in mezzanine and backplane designs.
How does the STL long-tail SMT termination on the TFM-147-22-STL-D-A-P-TR benefit solder joint reliability in thermally demanding environments?
The STL suffix indicates a longer SMT solder tail that increases the solder fillet height above the PCB pad, improving shear strength under thermal cycling from -55°C to +125°C and reducing the risk of solder joint fatigue cracking in ruggedized aerospace or industrial applications.
When should engineers choose the TFM-147-22-STL-D-A-P-TR over a lower pin-count TFM variant for a new board-to-board interconnect design?
The 94-pin TFM-147-22-STL-D-A-P-TR is the right choice when a design requires routing more than 80 differential pairs or mixed power and signal lines between two boards at .050" pitch without increasing connector width, as the dual-row layout doubles pin density compared to single-row alternatives at the same connector length.
