Frequently Asked Questions
What is the pitch and row configuration of the TFM-144-03-SM-D-LC connector?
The TFM-144-03-SM-D-LC uses a 0.050-inch (1.27 mm) pitch in a dual-row layout with 144 total positions, providing 72 positions per row. This fine pitch enables high-density signal routing in compact PCB designs where board space is limited.
Which high-density PCB designs benefit most from using the TFM-144-03-SM-D-LC in a surface-mount assembly process?
Designs requiring 144 signal connections within a minimal footprint benefit most, including server backplanes, telecom line cards, and modular test instrumentation. The SMT termination style supports reflow soldering at standard 260°C peak temperatures, making it compatible with automated assembly lines and reducing hand-soldering rework.
How does the Tiger Eye contact technology in the TFM-144-03-SM-D-LC improve long-term connection reliability?
Tiger Eye contacts provide a wiping-action interface that displaces surface contaminants during mating, maintaining low contact resistance below 20 milliohms over thousands of insertion cycles. This mechanism is critical for board-to-board links in industrial and telecom applications subject to vibration and repeated field maintenance.
When should an engineer consider the TFM-144-03-SM-D-LC over connectors with larger 0.100-inch pitch?
Designers should choose TFM-144-03-SM-D-LC when routing more than 100 signals across a board-to-board interface requires keeping the connector footprint under 10 mm in width. The 0.050-inch pitch halves the interconnect length versus 0.100-inch alternatives, which is decisive for high-speed differential pairs above 1 GHz where trace length matching is critical.
