What are the key features of TFM-120-22-F-D-LC?
- 40-position dual-row surface mount terminal strip with 0.050 inch (1.27 mm) pitch for high-density board-to-board interconnection
- Gold flash over nickel contact finish on mating surface with tin-over-nickel termination for reliable signal integrity
- Split board lock mounting option provides secure mechanical retention without solder for robust SMT assembly
What is TFM-120-22-F-D-LC used for?
The TFM-120-22-F-D-LC is suited for high-density PCB interconnect applications in telecommunications, data storage, and industrial control systems requiring 40 contacts at 0.050 inch pitch. Its surface mount vertical footprint and split board lock design make it ideal for compact board-to-board or board-to-cable connections in space-constrained enclosures. Engineers deploying it in medical devices and test instrumentation benefit from the gold-flash mating contacts delivering consistent low-resistance connections across thousands of mating cycles.

Frequently Asked Questions
What contact pitch does the TFM-120-22-F-D-LC use, and how does that affect PCB routing density?
The TFM-120-22-F-D-LC uses a 0.050 inch (1.27 mm) pitch across 40 positions in a dual-row layout, allowing high-density signal routing on PCBs where board space is constrained. This fine pitch reduces the connector footprint to approximately 1.275 inches in length, enabling tighter component placement compared to 0.100 inch pitch alternatives.
Which industrial or instrumentation designs benefit most from the TFM-120-22-F-D-LC split board lock feature?
Applications requiring secure mechanical retention before solder reflow, such as automated test equipment, industrial motor drives, and portable medical instruments, benefit greatly from the split board lock. The lock holds the connector at the 0.050 inch pitch footprint during SMT assembly, preventing misalignment across the 40-position, 1.275 inch body length and improving first-pass yield.
How does the gold flash over nickel mating finish on the TFM-120-22-F-D-LC compare to a standard tin finish for signal integrity?
Gold flash (3 micro-inches minimum) over 50 micro-inches of nickel provides lower and more stable contact resistance than plain tin on the 40 mating positions, particularly in low-level signal circuits below 100 mV. The nickel barrier prevents tin whisker formation, maintaining reliable performance across the connector's rated temperature and mating cycle life.
