What are the key features of TFM-136-22-FM-D-A-P-TR?
- SAMTEC Tiger Eye high-reliability contact technology providing low contact resistance below 20 mΩ and superior mating durability across 500+ insertion cycles
- 0.050 inch (1.27 mm) pitch dual-row design delivering 72 contact points in a compact footprint for high-density mezzanine and SOM board interfaces
- Floating mount (FM) feature absorbing up to ±0.5 mm PCB misalignment to ease assembly tolerances in stacked board configurations
What is TFM-136-22-FM-D-A-P-TR used for?
The TFM-136-22-FM-D-A-P-TR is designed for high-reliability mezzanine, SOM, and FPGA daughtercard interconnects in aerospace, defense, and industrial computing systems requiring consistent performance across thousands of mating cycles. The 0.050 inch pitch and 72-position dual-row layout pack high signal density into a minimal PCB footprint, enabling compact module designs without sacrificing signal integrity. Its floating mount and polarization features simplify board alignment and prevent incorrect mating in automated and field-assembled systems.

Frequently Asked Questions
What contact pitch and total position count does the TFM-136-22-FM-D-A-P-TR provide for high-density board interconnects?
The TFM-136-22-FM-D-A-P-TR uses a 0.050 inch (1.27 mm) pitch in a dual-row configuration with 36 positions per row, yielding 72 contact points total. This density is approximately 4 times higher than standard 2.54 mm pitch connectors for the same connector length, making it ideal for high-speed data interfaces, FPGA I/O expansion, and SOM carrier board designs where PCB area is limited.
How does the floating mount feature of the TFM-136-22-FM-D-A-P-TR help in stacked PCB assemblies with manufacturing tolerances?
The FM (floating mount) designation on the TFM-136-22-FM-D-A-P-TR allows the connector body to float by up to ±0.5 mm in X and Y axes, compensating for PCB-to-PCB misalignment caused by manufacturing tolerances, thermal expansion differentials of up to 15 ppm/°C between dissimilar substrates, and mechanical stack-up variation in multi-board enclosures. This reduces the risk of broken solder joints or damaged contacts when two PCBs are screwed into a chassis at fixed standoff heights.
In which demanding application segments does the Tiger Eye contact technology in the TFM-136-22-FM-D-A-P-TR outperform standard SMT connectors?
SAMTEC Tiger Eye contacts in the TFM-136-22-FM-D-A-P-TR maintain contact resistance below 20 mΩ after 500 or more mating cycles and across temperature ranges from -55°C to +125°C, meeting requirements for MIL-spec and aerospace-grade board interconnects. Standard SMT connectors without Tiger Eye technology may degrade to contact resistance above 50 mΩ after 200 cycles in humid or thermally cycling environments, making the TFM-136 series preferable for satellite electronics, avionics modules, and industrial motor drive control cards.
