Frequently Asked Questions
What contact finish does the TFC-110-02-L-D-A-K-TR use and why does it matter for reliability?
The TFC-110-02-L-D-A-K-TR features gold (10 µin) over nickel (50 µin) mating contact finish on phosphor bronze material. This finish provides excellent corrosion resistance and low contact resistance, ensuring signal integrity across all 20 positions through many thousands of mating cycles in demanding environments.
Which board stacking architectures benefit from the TFC-110-02-L-D-A-K-TR shrouded housing design?
The shrouded Tiger Eye housing prevents mismating and guides alignment in dual-board stacking configurations, making it ideal for embedded computing modules, mezzanine card assemblies, and industrial backplane systems that require 0.050" pitch, 20-position high-density interconnects with keyed polarization.
Is the TFC-110-02-L-D-A-K-TR suitable for automated SMT assembly lines?
Yes, the TFC-110-02-L-D-A-K-TR comes in tape-and-reel (TR) packaging, making it directly compatible with automated pick-and-place equipment. Its tin termination finish with nickel barrier supports standard reflow soldering profiles, enabling efficient high-volume PCB assembly for all 20 positions.
When is the TFC-110-02-L-D-A-K-TR a better choice than a higher-pitch board stacking connector?
The 0.050" (1.27 mm) pitch Tiger Eye connector outperforms larger-pitch alternatives when PCB real estate is critical. Fitting 20 positions in the dual-row 1.27 mm pitch format halves the board footprint compared to a 2.54 mm pitch alternative, while maintaining reliable phosphor bronze contacts and gold mating finish suitable for moderate-cycle-count board stacking applications.
