What are the key features of SFM-137-T2-F-D-A-P-TR?
- 74-position dual-row layout on 0.050 inch (1.27 mm) pitch delivers very high signal density within a compact SMT footprint
- High-reliability gold-plated precision contacts rated for hundreds of mating cycles, suited for aerospace, medical, and test-equipment applications
- Tape-and-reel (TR) packaging supports automated SMT pick-and-place assembly at production volumes with consistent placement accuracy
What is SFM-137-T2-F-D-A-P-TR used for?
The SFM-137-T2-F-D-A-P-TR is designed for high-density board-to-board interconnects in applications such as server backplanes, FPG-based development platforms, and compact module carrier boards where 74 dual-row contacts are needed in a minimal PCB footprint. Its 0.050-inch pitch and precision gold contacts make it suitable for high-speed digital signal interfaces operating at frequencies where contact resistance and inductance must be tightly controlled. The surface-mount configuration and tape-and-reel format enable integration into fully automated SMT assembly lines for medium- to high-volume production.

Frequently Asked Questions
How many signal contacts does the SFM-137-T2-F-D-A-P-TR provide, and what pitch allows that density?
The SFM-137-T2-F-D-A-P-TR provides 74 positions arranged in a dual-row configuration on a 0.050 inch (1.27 mm) pitch. This fine pitch allows packing 74 contacts into a connector body roughly half the length that an equivalent 0.100 inch pitch connector would require, directly enabling very high-density board-to-board interfaces on area-constrained PCBs such as compact compute modules or FPGA daughter cards.
For high-speed digital designs, how does the contact finish on SFM-137-T2-F-D-A-P-TR affect signal integrity at the interface?
The SFM-137-T2-F-D-A-P-TR uses a gold contact finish on its 74 precision machined contacts, which provides lower and more consistent contact resistance compared to tin-finished alternatives, typically below 20 milliohms per contact. Lower contact resistance reduces resistive voltage drop and minimizes impedance discontinuities at the connector interface, helping maintain signal integrity for high-speed differential pairs and single-ended signals up to several hundred MHz.
What tape-and-reel packaging benefits does the SFM-137-T2-F-D-A-P-TR offer for automated assembly of dense PCBs?
The -TR suffix on the SFM-137-T2-F-D-A-P-TR indicates tape-and-reel packaging, which feeds directly into standard SMT pick-and-place machines without manual loading. This eliminates placement orientation errors common with bulk-packed connectors, supports placement rates consistent with other fine-pitch SMT components, and is essential when assembling high-density 74-position dual-row connectors accurately across large production volumes.
Which SAMTEC header series mates with SFM-137-T2-F-D-A-P-TR for a 0.050 inch pitch dual-row 74-position interface?
The SFM-137-T2-F-D-A-P-TR mates with SAMTEC's TSM series 0.050 inch pitch dual-row terminal strips in the 37-per-row (137) count. These TSM headers are available with multiple termination styles and contact heights from about 0.6 mm to 4.1 mm, allowing designers to select the exact board-to-board stacking height required while maintaining a matched 74-position interface at 0.050 inch pitch.
