What are the key features of TFM-137-12-S-D-A-P-TR?
- High-reliability Tiger Eye contact system ensures superior electrical performance and long mating life
- Ultra-fine 0.050" (1.27 mm) pitch enables high-density interconnect in space-constrained designs
- Dual-row SMT configuration with 74 total positions supports complex signal routing in compact footprints
What is TFM-137-12-S-D-A-P-TR used for?
TFM-137-12-S-D-A-P-TR is well suited for high-density board-to-board interconnect in telecommunications equipment and computing platforms where space is at a premium. Its Tiger Eye contact technology and 1.27 mm pitch make it a strong choice for test and measurement instruments requiring reliable signal integrity across hundreds of mating cycles. The dual-row SMT design also supports ruggedized industrial and mil-aero assemblies where compact connector footprints and secure solder attachment are essential.

Frequently Asked Questions
How many total contact positions does the TFM-137-12-S-D-A-P-TR provide, and how are they arranged?
The TFM-137-12-S-D-A-P-TR is a dual-row terminal strip with 37 positions per row, giving 74 total contacts arranged on a 0.050" (1.27 mm) pitch. This high-density layout allows designers to route a large number of signals across a very compact PCB footprint of less than 50 mm in mated length.
What board-to-board mating solutions are compatible with Samtec TFM-137-12-S-D-A-P-TR in stack-height-sensitive designs?
The TFM-137-12-S-D-A-P-TR mates with Samtec's corresponding TFM receptacle series. These mating pairs support stack heights as low as 2 mm, making them suitable for ultra-thin PCB assemblies where vertical clearance is constrained to under 5 mm between boards.
What current rating per contact does the TFM-137-12-S-D-A-P-TR support, and how does this affect power distribution in a multi-rail design?
Each contact in the TFM-137-12-S-D-A-P-TR is rated for up to 1 A of current, with a contact resistance typically below 20 mΩ. In a multi-rail design with 74 contacts, selective power contacts can carry aggregated currents while signal contacts maintain low crosstalk, supporting mixed-signal architectures at 1.27 mm pitch.
Is TFM-137-12-S-D-A-P-TR a cost-effective alternative to larger-pitch connectors in dense FPGA carrier board designs?
Yes. The TFM-137-12-S-D-A-P-TR provides 74 contacts at 1.27 mm pitch, compared to standard 2.00 mm pitch connectors that would need roughly twice the PCB area for the same count. This makes it a compelling lower-footprint option for FPGA carrier boards operating at 3.3 V or 1.8 V I/O where board space is critical.
