What are the key features of TFM-144-32-SM-D-A-P-TR?
- SAMTEC Tiger Eye contact system maintaining contact resistance below 20 mΩ after 500+ mating cycles for high-reliability board-to-board interconnection
- 0.050 inch (1.27 mm) pitch dual-row layout with 88 total contact positions enabling ultra-high-density signal routing in a compact SMT footprint
- Polarization (P suffix) and tape-and-reel (TR) packaging ensuring correct assembly orientation and supporting automated pick-and-place manufacturing at scale
What is TFM-144-32-SM-D-A-P-TR used for?
The TFM-144-32-SM-D-A-P-TR is designed for high-density mezzanine, SOM, and FPGA expansion card interconnects in aerospace avionics, defense electronics, and industrial computing platforms where signal density and long-term reliability are critical requirements. The 0.050 inch pitch dual-row design provides 88 contact points in a connector length equivalent to fewer than 25 pins at standard 2.54 mm pitch, enabling compact board-to-board interfaces for high-speed data buses, GPIO expansion, and mixed-voltage power routing. Surface-mount construction with tape-and-reel packaging supports cost-effective high-volume SMT assembly in automated production environments.

Frequently Asked Questions
How many total contact positions does the TFM-144-32-SM-D-A-P-TR provide and what is its pin pitch?
The TFM-144-32-SM-D-A-P-TR provides 88 contact positions total in a dual-row configuration on a 0.050 inch (1.27 mm) pitch, with 44 positions per row. This contact density is approximately 4 times higher than equivalent 2.54 mm pitch connectors for the same physical length, making it ideal for FPGA I/O banks, high-speed SerDes interfaces, and module carrier boards where dozens of signals must cross a board-to-board boundary within a 55 mm connector length.
What reliability advantages does Tiger Eye contact technology provide for the TFM-144-32-SM-D-A-P-TR in harsh environments?
The Tiger Eye contacts in the TFM-144-32-SM-D-A-P-TR maintain contact resistance below 20 mΩ through 500 or more mating cycles and across the full -55°C to +125°C temperature range. Standard SMT connectors often exhibit contact resistance exceeding 50 mΩ after 200 cycles under humidity or thermal shock, whereas the Tiger Eye twin-beam design provides redundant contact points on each pin, ensuring reliable signal continuity in avionics, satellite payloads, and industrial motor drive modules subject to vibration and thermal cycling.
When should a designer choose the TFM-144-32-SM-D-A-P-TR over the TFM-136-22-FM-D-A-P-TR for a high-density mezzanine interface?
The TFM-144-32-SM-D-A-P-TR offers 88 contact positions versus the 72 positions of the TFM-136-22-FM-D-A-P-TR, providing 22% more I/O in the same 0.050 inch pitch dual-row format, making it preferable when FPGA pin counts or high-speed bus widths require more than 72 signals. The TFM-144 is the better choice for interfaces such as 64-bit memory buses with control signals, PCIe x8 with sideband, or combined Ethernet plus GPIO expansions exceeding 72 pins, while the TFM-136 suits designs where 72 pins are sufficient and a shorter connector fits the PCB layout better.
