Key Features
- 92-position dual-row layout at 0.050" (1.27 mm) pitch supporting very high signal density in compact PCB designs
- Tiger Eye dual-beam contact geometry ensuring contact resistance below 20 milliohms across 500+ mating cycles
- SMT-compatible design enabling automated reflow soldering at peak temperatures up to 260°C for high-volume production
Applications
The TFC-146-02-FM-D-A-K is designed for high-channel-count board-to-board and mezzanine card interconnect applications in telecommunications, high-performance computing, and data acquisition systems. Its 92-position dual-row 0.050" pitch footprint efficiently consolidates a large number of signal and power lines into a small connector area on dense PCBs. It is well suited for FPGA evaluation modules, storage backplanes, and industrial I/O expansion cards requiring reliable high-density interconnects.

Frequently Asked Questions
How many signal positions and what pitch does the TFC-146-02-FM-D-A-K provide for high-density designs?
The TFC-146-02-FM-D-A-K offers 92 positions arranged in dual rows at a 0.050" (1.27 mm) pitch, making it one of the higher pin count options in the SAMTEC TFC series. This density is ideal for FPGA carrier boards, high-speed data acquisition cards, and telecommunications line cards requiring many simultaneous signal connections.
In a high-speed digital design, what contact resistance does the TFC-146-02-FM-D-A-K maintain over its service life?
The Tiger Eye contacts in the TFC-146-02-FM-D-A-K maintain contact resistance below 20 milliohms after 500 or more mating cycles. The dual-beam wiping geometry continuously cleans the mating surface, ensuring stable signal integrity for differential pairs and high-speed digital signals up to several gigabits per second in data communications equipment.
Can the TFC-146-02-FM-D-A-K be processed through standard SMT assembly lines without special tooling?
Yes, the TFC-146-02-FM-D-A-K is a surface mount device compatible with standard pick-and-place equipment and reflow soldering at peak temperatures up to 260°C. No special tooling is needed, making it straightforward to integrate into existing SMT assembly lines for telecommunications, computing, and industrial PCB manufacturing.
When would a designer select the 92-position TFC-146-02-FM-D-A-K instead of a lower pin count connector like the 72-position TFC-136?
A designer would select the TFC-146-02-FM-D-A-K when an application requires more than 72 simultaneous signal connections within the same 0.050" pitch dual-row format. With 92 pins, it accommodates additional I/O lines for complex FPGA interfaces, multi-channel ADC connections, or backplane designs where 20 or more extra signal channels are needed compared to the 72-position TFC-136 variant.
