Key Features
- 80-position dual-row SMT terminal strip at .050" (1.27 mm) pitch, providing 160 total contacts in a 2.375 inch body for high-density interconnects
- Gold (30 µin) over nickel (50 µin) mating finish with Tiger Eye contact geometry ensures reliable low-resistance mating over thousands of insertion cycles
- Split board lock (LC) option mechanically secures the connector to the PCB, improving vibration resistance in harsh environments
Applications
The TFM-140-22-H-D-LC is designed for high-reliability board-to-board mezzanine applications in military electronics, aerospace avionics, and high-performance computing modules where 80-pin connectivity at .050" pitch is needed. Its split board lock and gold contact finish ensure mechanical stability and signal integrity under vibration and repeated mating cycles.

Frequently Asked Questions
What is the total contact count and body length of TFM-140-22-H-D-LC, and how does that help in dense designs?
TFM-140-22-H-D-LC provides 80 positions (160 contacts in dual row) within a 2.375 inch body at .050" (1.27 mm) pitch. This packs twice the contact density of equivalent .100" pitch connectors into the same board area, enabling high-bandwidth board-to-board links in FPGA mezzanine and avionics applications where every millimeter of PCB space is critical.
How does the split board lock (LC) feature on TFM-140-22-H-D-LC benefit systems exposed to vibration?
The split board lock mechanically anchors the TFM-140-22-H-D-LC body to the PCB at multiple points, preventing connector rocking or lifting under mechanical vibration. In aerospace and defense hardware operating under MIL-STD-810 vibration profiles, this retention method maintains solder joint integrity across all 80 positions and prevents intermittent contact at the 1.27 mm pitch interface.
For a military-grade mezzanine card, when should TFM-140-22-H-D-LC be chosen over a lower-pitch alternative?
TFM-140-22-H-D-LC at .050" (1.27 mm) pitch is preferred when 80 or more signals must cross a board interface within a 2.375 inch span. Its gold contact finish and Tiger Eye design support high-cycle mating above 200 insertions, while the LC board lock meets vibration retention requirements typical of MIL-grade mezzanine standards, making it superior to lower-reliability alternatives.
