What are the key features of TFM-146-13-STL-D?
- 92-position dual-row high-reliability Tiger Eye terminal strip at 0.050" (1.27 mm) pitch for dense multi-signal board interconnections in demanding environments
- Gold-plated contacts with high-reliability Tiger Eye contact geometry providing consistent normal force, low contact resistance, and extended mating cycle durability
- Through-hole STL (surface-to-liner) termination style offering robust mechanical retention and stable electrical connection under vibration and thermal cycling conditions
What is TFM-146-13-STL-D used for?
The TFM-146-13-STL-D is designed for high-reliability applications in aerospace, defense, and high-performance computing boards requiring 92 dual-row signal connections at 0.050" pitch. Its Tiger Eye contact design ensures reliable wiping action and consistent electrical performance over thousands of mating cycles in mission-critical systems. The STL termination provides additional mechanical anchoring, making this connector suitable for backplane and mezzanine card interconnections in vibration-prone environments.

Frequently Asked Questions
What total position count and pitch does the TFM-146-13-STL-D offer for high-density board designs?
The TFM-146-13-STL-D provides 92 total positions in a dual-row arrangement at a 0.050" (1.27 mm) pitch, delivering 46 contacts per row. This fine pitch allows a very high signal density in a compact linear footprint, essential for FPGA expansion cards, backplane daughter boards, and high-speed data routing in constrained PCB areas.
How does the STL (surface-to-liner) termination of the TFM-146-13-STL-D improve mechanical reliability?
The STL termination style anchors the connector through the PCB liner, providing a mechanical bond that resists pull-out forces and lateral shifting during vibration or thermal expansion cycles. This is particularly valuable in aerospace and defense assemblies where connectors at 0.050" pitch must maintain contact integrity under shock loads of tens of g and temperature excursions from -55°C to +125°C.
When is the TFM-146-13-STL-D preferred over a lower-pin-count fine-pitch connector for a given design?
The TFM-146-13-STL-D with 92 positions is preferred when a design requires a single high-density connector to replace multiple smaller connectors, reducing connector count and board routing complexity. A single 92-position 0.050" pitch connector consolidates signals that might otherwise require 3 to 4 separate 2.54 mm pitch connectors, simplifying BOM management and improving signal ground return path integrity.
