Key Features
- 90-position dual-row design at 0.050 inch (1.27 mm) pitch enabling ultra-high-density board connector footprints in constrained PCB layouts
- Gold 3 µin contact plating on phosphor bronze contacts for reliable low-resistance mating with minimal signal loss across all 90 positions
- Tiger Eye cost-effective terminal strip construction with peg (PEG) board mount and tape-and-reel packaging for automated SMT assembly
Applications
The TFC-145-02-F-D-A-K-TR is designed for high-density board-to-cable and board-to-board applications in test equipment, industrial control systems, and communication modules where 90 positions must be routed across a 0.050 inch pitch footprint. The phosphor bronze contacts with gold mating finish provide consistent low-resistance connections across repeated insertion cycles, making the connector suitable for instrumentation and data acquisition systems. Tape-and-reel packaging supports automated pick-and-place assembly for production environments demanding throughput with high connector density.

Frequently Asked Questions
How does the 0.050 inch pitch of the TFC-145-02-F-D-A-K-TR compare to standard 0.100 inch pitch connectors for PCB density?
At 0.050 inch (1.27 mm) pitch, the TFC-145-02-F-D-A-K-TR packs 90 positions into a board length of approximately 2.375 inches, which is roughly half the footprint length required for an equivalent 0.100 inch pitch connector. This density advantage is critical in compact test equipment, data acquisition cards, and portable instrumentation where board space is limited but signal count is high.
What contact material and finish does the TFC-145-02-F-D-A-K-TR use, and how does this affect long-term reliability?
The TFC-145-02-F-D-A-K-TR uses phosphor bronze contacts with gold (3 µin) mating finish and matte tin termination finish. Phosphor bronze provides high spring force for consistent contact pressure across 90 positions, while the gold mating surface delivers below 10 mΩ contact resistance and corrosion resistance over thousands of mating cycles in industrial and instrumentation environments.
When should a designer choose the TFC-145-02-F-D-A-K-TR over a higher-pitch connector for a cable harness application?
The TFC-145-02-F-D-A-K-TR at 0.050 inch pitch is the right choice when a design requires 90 signals in a single connector body but board and cable harness width must be minimized. For signal-level applications with currents below 1 A per contact and operating temperatures within the Tiger Eye connector range, the TFC series offers a cost-effective alternative to higher-pitch or fine-pitch ZIF connectors while maintaining gold-contact reliability.
