What are the key features of TFM-147-22-L-D-A-P-TR?
- 94-position dual-row layout at 0.050 inch (1.27 mm) pitch supports ultra-high-density signal routing in FPGA, processor, and backplane mezzanine applications
- Long SMT tail (L) provides additional solder joint length for improved mechanical retention and thermal cycle reliability on the PCB
- Tiger Eye contact design delivers consistent wiping-action engagement and low resistance across 500+ mating cycles
- Tape-and-reel (TR) packaging enables high-speed automated SMD pick-and-place assembly in volume production
What is TFM-147-22-L-D-A-P-TR used for?
The TFM-147-22-L-D-A-P-TR serves high-density mezzanine card interconnects in FPGA compute boards, network switch line cards, and defense processing modules that demand 94 signal paths through a compact 0.050 inch pitch SMT footprint. Its long solder tail provides enhanced mechanical pull strength compared to standard-tail variants, improving reliability under vibration and thermal cycling in harsh environments. Tape-and-reel delivery supports automated SMT assembly for high-volume production of embedded computing and telecommunications hardware.

Frequently Asked Questions
How many signal positions does the TFM-147-22-L-D-A-P-TR provide in its dual-row configuration?
The TFM-147-22-L-D-A-P-TR provides 94 total positions arranged in 2 rows of 47 contacts each at a 0.050 inch (1.27 mm) pitch. This high contact density makes it suitable for FPGA I/O expansion buses, high-speed digital signal distribution, and multi-rail power and signal mezzanine interconnects in compact embedded systems.
What advantage does the long (L) SMT tail style offer over standard-length tail connectors in demanding environments?
The long SMT tail extends the solder joint length beyond the PCB surface, increasing the solder fillet area and improving pull-out strength by 20% to 40% compared to standard-length tails. This enhanced retention is critical for mezzanine connectors in defense avionics and industrial automation equipment subjected to continuous mechanical vibration above 10 g and wide temperature cycling from -40°C to +85°C.
How does the Tiger Eye contact technology in the TFM-147-22-L-D-A-P-TR maintain signal integrity over its rated service life?
SAMTEC Tiger Eye contacts employ a stamped leaf geometry that generates a controlled wiping stroke during mating, mechanically displacing surface oxides and contaminants. This action maintains contact resistance below a few milliohms for a minimum of 500 mating cycles, ensuring reliable signal integrity for all 94 positions across the connector's service life in field-serviceable mezzanine module applications.
When does tape-and-reel packaging make the TFM-147-22-L-D-A-P-TR more economical than tray-packaged alternatives?
Tape-and-reel packaging becomes more economical than tray alternatives at production volumes above approximately 500 PCBs per batch, where automated pick-and-place throughputs exceeding 1000 placements per hour eliminate the manual handling labor required to individually retrieve and orient tray-packaged parts. For the 94-pin TFM-147-22-L-D-A-P-TR, this labor saving can reduce per-connector assembly cost by several minutes per unit in high-volume runs.
