What are the key features of TFM-143-32-SM-D-A-P-TR?
- 0.050" (1.27 mm) pitch dual-row 43-position surface mount layout with 86 contacts in a minimal PCB footprint
- Surface mount (SM) termination enabling reflow solder assembly without through-hole drilling, reducing PCB fabrication cost
- Tiger Eye contact geometry providing low insertion force and consistent contact resistance across all 86 positions
What is TFM-143-32-SM-D-A-P-TR used for?
The TFM-143-32-SM-D-A-P-TR surface mount terminal strip is designed for high-density mezzanine and board-to-board interconnects in server modules, FPGA daughter cards, and industrial automation controllers. Its 86-contact dual-row layout at 0.050" pitch consolidates multiple signal and power connections into a single compact footprint, reducing total connector count on the PCB. The surface mount termination and tape-and-reel packaging are optimized for automated reflow solder processes in high-volume production lines.

Frequently Asked Questions
What does the SM designator mean for TFM-143-32-SM-D-A-P-TR, and how does it affect PCB assembly process selection?
The SM designator in TFM-143-32-SM-D-A-P-TR indicates a surface mount termination style, meaning the connector leads are soldered to PCB surface pads rather than through plated holes. Surface mount assembly requires a reflow solder profile, typically with peak temperatures around 260°C, and eliminates the need for 86 drilled vias that through-hole variants would require. This simplifies PCB fabrication and allows placement on both sides of the board.
How does the TFM-143-32-SM-D-A-P-TR handle signal integrity for high-speed differential pairs at its 0.050" pitch?
At a 0.050" (1.27 mm) pitch, the TFM-143-32-SM-D-A-P-TR can accommodate differential pairs with spacing suitable for controlled-impedance PCB traces at 50 Ω single-ended or 100 Ω differential. Engineers should design pad patterns with attention to adjacent-contact crosstalk, particularly for signal frequencies above 500 MHz. SAMTEC specifies the Tiger Eye contact geometry to maintain consistent electrical performance across all 86 contact positions even at high frequencies.
For a high-volume manufacturing program, what are the lead time and packaging considerations when ordering TFM-143-32-SM-D-A-P-TR?
The TFM-143-32-SM-D-A-P-TR is supplied in tape-and-reel (TR) format suited for automated pick-and-place equipment, with reel quantities typically ranging from 500 to 2,000 pieces per reel. Standard lead times for SAMTEC TFM series connectors are generally 4 to 14 weeks depending on stock availability. Procurement teams should verify RoHS-compliant (lead-free) plating options and confirm the A-P suffix indicating specific plating when placing production purchase orders.
