Key Features
- 74-position dual-row layout at 0.050" (1.27 mm) pitch delivers 37 contact pairs in a high-density surface mount footprint
- Full-mount (FM) termination style provides low-profile solder tails flush to the PCB for reliable reflow soldering
- Tiger Eye cost-optimized contact design maintains reliable signal integrity while reducing connector cost compared to machined-contact alternatives
Applications
The TFC-137-02-FM-D-A serves high-density board interconnection requirements in computing modules, telecommunications line cards, and industrial automation controllers. With 74 positions at 0.050" pitch, it routes 37 signal pairs across a compact board edge, enabling modular system designs with minimal connector overhead. The full-mount termination style ensures a stable, low-profile solder joint compatible with standard SMT reflow processes.

Frequently Asked Questions
How many signal pairs can TFC-137-02-FM-D-A carry and what is its contact pitch?
The TFC-137-02-FM-D-A carries 37 signal pairs across its 74 positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch. This density is twice that of standard 0.100" pitch connectors, making it well-suited for computing line cards, telecom modules, and industrial controllers where a large number of signals must cross a board boundary within a short span.
What PCB assembly process is TFC-137-02-FM-D-A designed for, and does it require special tooling?
The TFC-137-02-FM-D-A is designed for standard surface mount technology (SMT) reflow soldering, compatible with paste-in-pad processes and convection reflow ovens reaching 260°C peak temperature. The full-mount (FM) termination style provides flat solder tails that lie flush to the PCB pad, eliminating the need for special tooling or hand soldering for its 74-position footprint.
When would TFC-137-02-FM-D-A be a more practical choice than TFC-144-02-FM-D-A or TFC-131-02-FM-D-A-K-TR?
TFC-137-02-FM-D-A with 74 positions is the right choice when a design requires more than the 62 positions of TFC-131-02-FM-D-A-K-TR but fewer than the 88 positions of TFC-144-02-FM-D-A, providing a mid-range option at 37 contact pairs. It avoids the excess unused contacts of the larger variant while still exceeding the smaller connector's capacity, optimizing both PCB space usage and component cost for the specific signal count required.
