What are the key features of TFM-146-12-STL-D-A-P-TR?
- Tiger Eye short-tail (STL) SMT termination minimizes solder-tail length below the PCB, reducing clearance requirements and enabling tighter board-to-board stack heights across 92 dual-row positions
- 92-contact dual-row layout at 0.050" (1.27 mm) pitch delivers ultra-high signal density for advanced FPGA, telecom, and computing board interconnect designs
- Polarization key and tape-and-reel (TR) packaging ensure mis-insertion prevention and seamless automated pick-and-place compatibility in high-volume SMT manufacturing
What is TFM-146-12-STL-D-A-P-TR used for?
TFM-146-12-STL-D-A-P-TR is intended for high-density board-to-board signal interconnect in network switching platforms, FPGA development systems, and rugged military electronics where 92 signals must be reliably carried at 1.27 mm pitch with minimal PCB height impact. The short-tail SMT termination reduces the clearance footprint below the PCB plane, which is particularly valuable in ultra-slim stacked-board assemblies where board separation is constrained to under 3 mm. Tape-and-reel packaging ensures compatibility with high-speed automated SMT lines for industrial and mil-aero volume production.

Frequently Asked Questions
What is the contact count and pitch of TFM-146-12-STL-D-A-P-TR, and how does the dual-row layout benefit high-signal-count PCB designs?
TFM-146-12-STL-D-A-P-TR provides 92 total contact positions in a dual-row arrangement with 46 contacts per row on a 0.050" (1.27 mm) pitch. The dual-row layout concentrates 92 signal paths into a row length of approximately 59 mm, significantly reducing the PCB area required compared to single-row connectors for the same contact count in FPGA and computing module designs.
What advantage does the short-tail (STL) termination of TFM-146-12-STL-D-A-P-TR offer in slim stacked-board assemblies over standard-tail SMT versions?
The short-tail (STL) termination on TFM-146-12-STL-D-A-P-TR reduces the solder tail length that extends below the PCB surface, enabling board-to-board stack heights potentially below 2.5 mm. Standard-tail SMT variants may require 0.5 mm to 1 mm more vertical clearance due to longer solder tails, making the STL version the better choice for ultra-slim stacked architectures in portable instruments and compact embedded computing modules.
How does TFM-146-12-STL-D-A-P-TR compare to TFM-145-32-F-D-A-P-TR when selecting a 90+ contact connector for a space-constrained design?
TFM-146-12-STL-D-A-P-TR provides 92 contacts with short-tail SMT termination suited for minimum-clearance stacked-board designs, while TFM-145-32-F-D-A-P-TR offers 90 contacts with standard flat termination for conventional stack heights. When PCB-to-PCB separation must be minimized to under 2.5 mm, the STL termination of TFM-146 is preferred; for standard 3 mm or greater stack heights, TFM-145 is a simpler, equally reliable choice.
How does the polarization key of TFM-146-12-STL-D-A-P-TR protect high-speed signal integrity during board assembly and field replacement?
The polarization key on TFM-146-12-STL-D-A-P-TR physically blocks 180-degree mis-mating of the 92-pin dual-row connector, preventing reversed connections that could damage high-speed signals operating at 1.8 V or 3.3 V logic levels. During field replacement of modular boards, this mechanical keying ensures consistent correct orientation without relying on technician visual inspection across dense 1.27 mm pitch connector arrays.
