Frequently Asked Questions
How many signal positions does the TFC-128-02-L-D-A-K-TR provide, and what is the row pitch?
The TFC-128-02-L-D-A-K-TR provides 256 positions arranged in 2 rows of 128 contacts each, at a 0.050-inch (1.27 mm) pitch. This high-density layout allows designers to route a large number of signals in a compact PCB footprint, making it well-suited for FPGA interface boards and backplane interconnect applications.
What does the Tiger Eye contact technology in SAMTEC TFC series connectors offer over standard pin designs?
Tiger Eye contacts use a bifurcated beam design that provides two independent contact points per pin, delivering lower and more consistent contact resistance compared to single-beam alternatives. This dual-wipe action reduces sensitivity to contamination and oxidation, improving reliability over thousands of mating cycles in demanding environments such as test sockets and rack-mounted telecom equipment.
Is the TFC-128-02-L-D-A-K-TR packaged for automated assembly, and what reel format is used?
Yes, the TR suffix indicates tape-and-reel packaging, which is fully compatible with standard pick-and-place equipment. This packaging format supports high-volume, automated PCB assembly, reducing placement time and handling errors. The connector is a through-hole component and is typically placed before the reflow or wave-soldering step in the production process.
When would the TFC-128-02-L-D-A-K-TR be preferred over a lower-position SAMTEC TFC variant?
The 256-position TFC-128-02-L-D-A-K-TR is the right choice when the design requires 256 simultaneous signal connections in a single connector, avoiding the board-space overhead and assembly complexity of using multiple smaller connectors. It is especially advantageous in high-channel-count data acquisition systems, parallel bus interfaces operating above 100 MHz, and module-to-motherboard interconnects where a single mated pair must handle all I/O.
