What are the key features of TFC-120-02-F-D-A-K?
- 40 positions in dual-row 0.050" (1.27 mm) pitch for high-density signal routing in space-constrained PCB designs
- Gold-plated mating contacts on phosphor bronze for low contact resistance and extended mating cycle life
- Tiger Eye cost-effective design reduces BOM cost without sacrificing 0.050" pitch compatibility
- Peg board mounting option provides mechanical retention during soldering and system vibration
What is TFC-120-02-F-D-A-K used for?
The TFC-120-02-F-D-A-K is designed for high-density board-to-board and board-to-cable signal interconnects in telecommunications equipment, data storage backplanes, and embedded computing modules where 0.050" pitch reduces PCB real estate by up to 50% versus 0.100" alternatives. Its gold mating contacts ensure low-loss signal integrity for digital and mixed-signal circuits operating in industrial environments. The cost-effective Tiger Eye profile makes it a popular choice for volume production of networking cards and industrial I/O expansion boards.

Frequently Asked Questions
What pitch and position count does the TFC-120-02-F-D-A-K offer, and how does that compare to 0.100" alternatives?
The TFC-120-02-F-D-A-K provides 40 positions on a 0.050" (1.27 mm) dual-row pitch, which delivers the same pin count in roughly half the board footprint compared to equivalent 0.100" (2.54 mm) pitch connectors, enabling significant PCB space savings in high-density designs.
What contact material and finish does the TFC-120-02-F-D-A-K use, and why does it matter for signal integrity?
The connector uses phosphor bronze contacts with gold (3 µin minimum) mating finish, providing a contact resistance typically below 20 mΩ per pin. This low-resistance, corrosion-resistant interface preserves signal integrity for digital buses and mixed-signal circuits across thousands of mating cycles.
How does the peg board mounting feature of TFC-120-02-F-D-A-K assist automated PCB assembly?
The peg board mounting option locks the 40-position connector in place on the PCB during wave or reflow soldering, preventing movement that could cause misalignment of the 0.050" pitch contacts. This reduces rework rates in high-volume automated assembly and improves first-pass yield.
In which industrial or telecom system designs is the TFC-120-02-F-D-A-K a suitable interconnect choice?
Data storage backplanes, telecom line cards, and embedded single-board computers requiring 40-pin dual-row interfaces at 0.050" pitch benefit from this Tiger Eye series connector. Its gold contacts and tin-over-nickel termination also suit instrumentation and test-fixture applications that demand reliable connections over many insertion cycles.
