Key Features
- 98-position dual-row layout at 0.050" (1.27 mm) pitch delivers the highest signal density per inch among standard terminal strip families
- Tiger Eye dual-beam contact technology provides low insertion force mating with consistent contact resistance for reliable 98-pin signal integrity
- Flush-mount (FM) termination and tape-and-reel (TR) packaging optimized for automated SMT assembly in high-volume telecommunications and computing hardware
Applications
The TFC-149-02-FM-D-K-TR is designed for high-speed FPGA boards, backplane mezzanine cards, and high-density signal routing applications where 98 positions at 0.050-inch pitch are needed to route wide parallel buses and differential pairs across board-level interfaces. Its flush-mount surface-mount termination and tape-and-reel format make it ideal for automated high-volume production of networking line cards, server daughterboards, and test-and-measurement mainframes.

Frequently Asked Questions
How many positions and what pitch does the TFC-149-02-FM-D-K-TR support for high-density interconnects?
The TFC-149-02-FM-D-K-TR provides 98 positions in a dual-row configuration at 0.050-inch (1.27 mm) pitch. This allows 98-pin signal buses to be routed across a board interface that occupies roughly the same length as a 49-position 0.100-inch strip, achieving nearly double the interconnect density per board inch.
What is the significance of Tiger Eye contacts in the TFC-149-02-FM-D-K-TR for 98-pin mating reliability?
Tiger Eye contacts employ a dual-beam spring design that reduces per-pin insertion force while maintaining contact resistance below 20 mΩ across all 98 positions. This lowers total mating force for the full 98-pin connector to manageable levels and ensures consistent signal continuity across differential pairs and high-speed signal lines over repeated mating cycles.
Which high-speed digital applications benefit most from the 0.050-inch pitch of TFC-149-02-FM-D-K-TR?
FPGA development boards, server daughtercard-to-motherboard interfaces, and backplane mezzanine cards benefit most. A 98-position connector at 0.050-inch pitch can carry 49 differential pairs or a 96-bit-wide parallel bus in a compact footprint, supporting high-speed interfaces operating at data rates of several Gbps per lane.
Does the flush-mount termination of TFC-149-02-FM-D-K-TR offer any coplanarity advantage over standard SMT termination styles?
Yes. The flush-mount (FM) termination style ensures all 98 solder tails lie in a single plane within ±0.1 mm coplanarity tolerance, which is critical for automated optical inspection and consistent solder joint formation in reflow processes at temperatures up to 260°C. This reduces solder bridging risk on fine-pitch 0.050-inch footprints compared to non-flush variants.
