Key Features
- 44-position dual-row layout at 0.050" (1.27 mm) pitch achieves twice the density of standard 0.100" pitch terminal strips
- Tiger Eye contact technology provides low insertion force and reliable spring-action mating for consistent 44-pin signal integrity
- Tape-and-reel (TR) packaging with left-mount (LM) termination optimized for automated SMT assembly lines
Applications
The TFC-122-02-LM-D-A-K-TR is designed for compact high-speed digital systems, FPGAs, and memory modules where a 44-position, 0.050-inch pitch board-level terminal strip minimizes PCB footprint while maintaining signal integrity across dense interconnect buses. Its surface-mount configuration and tape-and-reel format make it ideal for high-volume production of telecommunications, networking, and test-and-measurement equipment.

Frequently Asked Questions
How does the 0.050-inch pitch of TFC-122-02-LM-D-A-K-TR compare to standard terminal strips in terms of board density?
The TFC-122-02-LM-D-A-K-TR operates at a 0.050-inch (1.27 mm) pitch, which is half the spacing of conventional 0.100-inch pitch strips. This allows 44 positions to occupy the same board length that a standard strip would use for only 22 positions, nearly doubling interconnect density.
What is Tiger Eye contact technology and why does it matter for 44-pin signal connections?
Tiger Eye contacts use a dual-beam, low-insertion-force spring design that maintains consistent contact resistance below 20 mΩ across 44 pins. This reduces connector mating force compared to traditional press-fit contacts and ensures reliable signal integrity in high-cycle board-level interconnect applications.
Which application boards benefit most from the TFC-122-02-LM-D-A-K-TR's high-density 0.050-inch pitch?
FPGA development boards, high-speed memory modules, and compact telecommunications line cards benefit most, as the 44-position, 0.050-inch pitch configuration supports dense multi-bit buses, differential pairs, and high-speed signals at frequencies up to several GHz within a minimal PCB footprint.
Does the tape-and-reel packaging of TFC-122-02-LM-D-A-K-TR support automated assembly, and at what volume?
Yes. The TR (tape-and-reel) suffix indicates it is packaged on standard reels, enabling automated pick-and-place at production speeds of thousands of placements per hour. This is well-suited for medium to high-volume SMT lines producing networking and computing hardware in batches exceeding 5,000 units.
