What are the key features of TFC-149-02-FM-D-A?
- 98-position dual-row terminal strip at 0.050" (1.27 mm) pitch supporting very high signal density on compact PCBs
- Tiger Eye dual-beam contact design providing contact resistance below 20 milliohms across 500+ mating cycles
- Surface mount (SMT) package compatible with automated reflow soldering up to 260°C peak temperature for efficient production
What is TFC-149-02-FM-D-A used for?
The TFC-149-02-FM-D-A is designed for very high channel count board-to-board and mezzanine interconnect applications in high-performance computing, FPGA development systems, and advanced telecommunications equipment. Its 98-position dual-row 0.050" pitch layout consolidates nearly 100 signal or power lines into a single compact connector footprint, minimizing PCB area usage on dense system boards. Storage backplanes, high-bandwidth data acquisition cards, and multi-lane serial interface boards benefit from its robust Tiger Eye contact technology.

Frequently Asked Questions
How many connections does the TFC-149-02-FM-D-A provide, and at what pitch spacing?
The TFC-149-02-FM-D-A provides 98 total positions in a dual-row configuration at 0.050" (1.27 mm) pitch. This high pin count within the compact 1.27 mm pitch dual-row format is particularly valuable for FPGA I/O expansion boards, storage backplanes, and high-speed data acquisition cards requiring nearly 100 simultaneous signal connections.
What contact resistance does the TFC-149-02-FM-D-A maintain, and over how many mating cycles?
The Tiger Eye contacts in the TFC-149-02-FM-D-A maintain contact resistance below 20 milliohms across 500 or more mating cycles due to the dual-beam wiping geometry that cleans oxidation from mating surfaces. This stable low resistance is essential for high-speed differential signal pairs and power distribution connections in computing and telecom systems.
Is the TFC-149-02-FM-D-A suitable for reflow soldering in an automated SMT production line?
Yes, the TFC-149-02-FM-D-A is a surface mount device fully compatible with automated pick-and-place equipment and standard reflow soldering at peak temperatures up to 260°C. Engineers can integrate it into existing SMT assembly lines without special fixtures, making it cost-effective for high-volume production of telecommunications line cards and computing backplane boards.
When is the 98-position TFC-149-02-FM-D-A preferred over the 92-position TFC-146 or smaller TFC variants?
The TFC-149-02-FM-D-A is selected when a design requires more than 92 simultaneous connections at 0.050" pitch, such as in FPGA-based systems with wide parallel buses or high-density I/O expansion modules. The 6 additional positions compared to the TFC-146 can accommodate extra ground pins, power rails, or sideband signals needed in complex multi-channel interface designs without requiring a second connector.
