What are the key features of TFM-139-32-STL-D-A-P-TR?
- Tiger Eye contacts on a fine 0.050" pitch ensure reliable dual-row signal integrity in high-vibration environments
- Stand-off low-profile (-STL) style provides controlled board-to-board spacing for mezzanine and backplane designs
- Tape-and-reel (-TR) packaging enables fully automated SMT pick-and-place for high-volume manufacturing
What is TFM-139-32-STL-D-A-P-TR used for?
The TFM-139-32-STL-D-A-P-TR serves board-to-board mezzanine connections in high-density embedded computing, network switching cards, and defense electronics where a controlled stand-off height and fine 0.050" pitch are required. Its 78-contact dual-row layout handles both signal and auxiliary power routing between stacked PCBs, making it well-suited for FPGA mezzanine modules, DSP carrier boards, and instrument backplanes.

Frequently Asked Questions
What total contact count does the TFM-139-32-STL-D-A-P-TR offer, and at what pitch are those contacts arranged?
The TFM-139-32-STL-D-A-P-TR provides 39 positions per row across 2 rows, giving 78 total contacts arranged on a 0.050" (1.27 mm) pitch. This combination of high contact count and fine pitch allows engineers to route a large number of digital signals, clocks, and auxiliary power rails across a mezzanine interface without significant PCB area penalty.
What does the stand-off low-profile (-STL) designation control in the TFM-139-32-STL-D-A-P-TR, and why does it matter for stacked PCB designs?
The -STL designation specifies a stand-off low-profile height, providing a defined gap between the mating PCBs when the TFM-139-32-STL-D-A-P-TR is installed. This controlled stand-off ensures consistent board-to-board spacing, which is critical for maintaining signal integrity on high-speed traces and for providing adequate clearance for components mounted on the lower board surface in 78-contact mezzanine assemblies.
For a compact FPGA carrier board, how does the tape-and-reel format of TFM-139-32-STL-D-A-P-TR support production scaling?
The -TR suffix indicates the TFM-139-32-STL-D-A-P-TR ships on tape and reel, compatible with standard SMT pick-and-place feeders used in production volumes exceeding thousands of units. For FPGA carrier boards requiring precise placement of the 78-pin dual-row connector, automated reel feeding eliminates manual alignment errors and supports consistent solder joint quality across high-volume build runs.
