Frequently Asked Questions
How many signal positions does TFM-143-12-STL-D-A-P-TR provide and at what pin pitch?
The TFM-143-12-STL-D-A-P-TR is a dual-row connector with 43 positions per row at a 0.050 inch (1.27 mm) pitch, providing 86 total contact positions. This high contact density makes it suitable for wide parallel data buses and mixed signal-power interfaces in compact mezzanine PCB assemblies requiring many connections within a small board area.
What distinguishes Tiger Eye contact technology in TFM-143-12-STL-D-A-P-TR from standard single-beam contacts?
Tiger Eye contacts use a dual-beam wiping action that creates two independent contact points per pin with gold plating for low contact resistance. This redundant contact geometry improves reliability under mechanical vibration, thermal cycling, and repeated mating cycles compared to single-beam designs, making TFM-143-12-STL-D-A-P-TR preferred for defense and aerospace applications requiring 500 or more mating cycles with consistent electrical performance.
For a rugged military electronics board stack, why choose TFM-143-12-STL-D-A-P-TR over a 0.100 inch pitch connector?
The 0.050 inch (1.27 mm) pitch of TFM-143-12-STL-D-A-P-TR provides twice the contact density of 0.100 inch pitch connectors, allowing 86 contacts in the space a standard 43-contact 0.100 inch connector would occupy. In military board stacks where PCB area is constrained and signal count is high, this density advantage reduces connector footprint significantly while Tiger Eye contacts maintain the high reliability and low contact resistance required for MIL-spec environments.
Does the tape-and-reel packaging of TFM-143-12-STL-D-A-P-TR support high-volume SMT assembly, and what reel quantities are typically available?
The TR (tape-and-reel) suffix on TFM-143-12-STL-D-A-P-TR confirms the connector is packaged for automated surface-mount pick-and-place assembly. SAMTEC typically provides tape-and-reel parts on reels of 100 or more pieces depending on the connector size, enabling continuous high-volume SMT production without manual loading. This is advantageous for programs requiring hundreds or thousands of boards per production run at standard SMT assembly cycle times.
