What are the key features of TFC-144-02-FM-D-K-TR?
- 88-position dual-row terminal strip at 0.050" (1.27mm) pitch supports up to 44 differential signal pairs in a single connector
- Tape-and-reel (-TR) packaging enables high-throughput pick-and-place automated SMT assembly
- Tiger Eye gold-plated contacts deliver reliable low-resistance mating across the full 88-pin array for high-speed signal integrity
What is TFC-144-02-FM-D-K-TR used for?
The TFC-144-02-FM-D-K-TR is designed for the highest pin-count board-to-board interconnects found in FPGA development kits, high-speed signal processing modules, and backplane systems where a single connector must carry 88 signals. Its 0.050" pitch dual-row layout supports 44 differential pairs, making it suitable for PCIe expansion, multi-channel ADC/DAC interfaces, and high-speed memory bus connections. The tape-and-reel packaging ensures compatibility with automated SMT lines producing hundreds to thousands of boards per run.

Frequently Asked Questions
How many differential pairs can the TFC-144-02-FM-D-K-TR support in a high-speed FPGA interconnect design?
The TFC-144-02-FM-D-K-TR provides 88 contacts in a dual-row 0.050" pitch configuration, supporting up to 44 differential pairs simultaneously. This makes it directly applicable to high-speed FPGA daughter card interfaces carrying LVDS, SERDES, or PCIe Gen 2 signal pairs at data rates up to several gigabits per second, consolidating what would otherwise require multiple lower pin-count connectors into a single 88-pin footprint.
Why does the -TR tape-and-reel suffix matter when ordering TFC-144-02-FM-D-K-TR for production builds?
The -TR suffix specifies tape-and-reel packaging, which is mandatory for pick-and-place SMT automated assembly of the 88-position connector at production volumes of 500 or more boards. Without tape-and-reel, connectors arrive in trays or tubes that require manual loading onto the feeder, slowing throughput and increasing placement error rates. Tape-and-reel format reduces per-unit assembly labor cost and maintains IPC-compliant registration accuracy across the 88 contact positions.
For a backplane carrying 80 or more signals, how does TFC-144-02-FM-D-K-TR compare to using two 44-position connectors?
Using a single TFC-144-02-FM-D-K-TR with 88 positions at 0.050" pitch requires only one PCB footprint and one solder joint array, reducing assembly steps by 50% compared to placing two separate 44-position connectors. The single-connector approach also eliminates the 2mm to 5mm gap between two connectors that would otherwise interrupt the ground or power plane continuity on the backplane, improving signal return path integrity for differential pairs above 500 MHz.
