Frequently Asked Questions
What pitch and contact count make the TFC-128-02-F-D-A suitable for high-density PCB designs?
The TFC-128-02-F-D-A provides 56 contacts on a 0.050 inch pitch in a dual-row arrangement spanning 1.525 inches, enabling twice the contact density of standard 0.100 inch pitch connectors for compact FPGA module and mezzanine board applications.
What contact finish does the TFC-128-02-F-D-A use, and how does this affect durability?
Mating contacts are gold-plated on phosphor bronze for low contact resistance and corrosion resistance through repeated insertions, while the termination side uses matte tin, supporting standard PCB soldering processes for all 56 pins.
How does the Tiger Eye design of TFC-128-02-F-D-A reduce procurement costs without sacrificing connector performance?
The Tiger Eye cost-effective series uses optimized stamping and selective gold plating only on the mating surface, cutting material cost while still delivering the contact force and alignment consistency required for reliable 56-position 0.050 inch pitch signal routing.
