What are the key features of TFM-137-32-F-D-A-P-TR?
- 37-position dual-row layout at 0.050 inch (1.27 mm) pitch provides 74 total contacts for high-density signal routing in a compact SMD footprint
- Female (-F) contact termination with Tiger Eye dual-beam design ensures consistent low contact resistance and reliable mating force across repeated cycles
- Tape-and-reel (-TR) packaging supports automated pick-and-place and lead-free reflow soldering for high-volume PCB production
What is TFM-137-32-F-D-A-P-TR used for?
The TFM-137-32-F-D-A-P-TR is suited for high-density mezzanine card, backplane, and FPGA expansion board interconnects where 74 signals must pass through a minimal PCB area. Its female dual-row contact arrangement mates with corresponding male TFM or TSM header pins, enabling modular board stacking configurations common in telecommunications, military, and industrial computing systems. The SMD footprint and reel packaging also make it an efficient choice for automated high-volume assembly of communication cards and data acquisition modules.

Frequently Asked Questions
How many contact positions does TFM-137-32-F-D-A-P-TR offer and how are they arranged?
The TFM-137-32-F-D-A-P-TR features 37 positions per row in a dual-row configuration, providing 74 total contacts. All contacts are spaced at 0.050 inch (1.27 mm) pitch, allowing engineers to route 74 discrete signals or 37 differential pairs through one connector with a significantly smaller board footprint than 0.100 inch pitch alternatives.
What does the -F designation in TFM-137-32-F-D-A-P-TR indicate about the contact type?
The -F suffix designates female contact termination, meaning the connector accepts male pin headers. The Tiger Eye female contact uses a dual-beam design that clamps around the mating pin, maintaining consistent contact pressure and keeping contact resistance typically below 20 mΩ even after 200 or more mating cycles in vibration-prone environments.
Is TFM-137-32-F-D-A-P-TR compatible with lead-free reflow soldering processes?
Yes, SAMTEC TFM series SMD connectors are rated for peak reflow temperatures up to 260°C, meeting IPC/JEDEC J-STD-020 requirements for lead-free assembly. The -TR tape-and-reel format ensures the 74-contact SMD body is presented at the correct pick-and-place orientation, minimizing handling errors and enabling single-pass reflow soldering in high-throughput SMT production lines.
How does TFM-137-32-F-D-A-P-TR compare to the TFM-132-32-F-D variant in terms of contact count?
The TFM-137-32-F-D-A-P-TR has 37 positions per row for 74 total contacts, whereas a TFM-132-32-F-D configuration would have 32 positions per row for 64 total contacts. This means the 137 variant provides 10 additional contacts per row, adding 20 more signal lines within a connector body approximately 6.35 mm longer — a worthwhile trade-off when signal count requirements exceed 64 pins in mezzanine or expansion card applications.
