What are the key features of TFM-139-22-L-D-A-P-TR?
- Tiger Eye contact design provides high spring retention force for reliable low-resistance connections across 1,000+ mating cycles
- Right-angle (L) dual-row 78-position layout at 0.050" pitch supports edge-board and right-angle mating configurations
- Tape-and-reel format with SMT termination enables automated high-volume pick-and-place PCB assembly
What is TFM-139-22-L-D-A-P-TR used for?
The TFM-139-22-L-D-A-P-TR is suited for right-angle board-to-board interconnect applications where signal lines must exit the PCB parallel to the board surface. Its 78-position dual-row Tiger Eye design is commonly used in aerospace avionics, ruggedized industrial modules, and embedded computing systems where reliable right-angle connections are required within tight chassis enclosures. The fine 0.050" pitch enables high signal density in compact modular PCB assemblies used across defense and instrumentation platforms.

Frequently Asked Questions
What does the right-angle (L) orientation on the TFM-139-22-L-D-A-P-TR enable in PCB layout?
The L suffix designates a right-angle orientation, meaning the mating direction runs parallel to the PCB surface rather than perpendicular. This allows signals to route horizontally out of the connector, which is essential for chassis-constrained designs where vertical clearance is limited. It supports board-to-board mating in 78-position dual-row configurations at 0.050" pitch without increasing PCB stack height.
How many positions and what contact pitch does the TFM-139-22-L-D-A-P-TR provide, and what density advantage does this offer?
The TFM-139-22-L-D-A-P-TR offers 78 positions in a dual-row arrangement with a 0.050" pitch. Compared to 0.100" pitch alternatives, this fine pitch provides approximately double the signal routing density in the same PCB edge length. This is particularly valuable for compact module interfaces in embedded computing, test systems, and data acquisition boards requiring numerous simultaneous signal channels.
When should a designer select TFM-139-22-L-D-A-P-TR over a vertical TFM variant for a given application?
A designer should select the right-angle TFM-139-22-L-D-A-P-TR when the mated PCB assembly must fit inside an enclosure with vertical height restrictions below approximately 8 mm, or when the connected cable or mating board exits horizontally from the PCB edge. Vertical TFM variants are preferred when boards stack directly on top of one another. The right-angle variant is common in rack-mount and card-edge industrial systems operating from -55°C to +125°C.
