Frequently Asked Questions
How many signal positions does the TFC-133-02-FM-D-A-K-TR provide and at what pitch spacing?
The TFC-133-02-FM-D-A-K-TR offers 66 positions arranged in a dual-row configuration at 0.050 inch (1.27 mm) pitch. This high-density layout supports 33 positions per row, enabling simultaneous routing of multiple parallel data buses, power rails, and ground references within a footprint smaller than 42 mm in length, making it suitable for space-constrained mezzanine PCB stacking applications.
What assembly process does the -TR suffix indicate and how does it affect production throughput?
The -TR suffix designates tape-and-reel packaging, confirming the TFC-133-02-FM-D-A-K-TR ships on a standard EIA-481 carrier reel compatible with automated SMT pick-and-place machines. This packaging eliminates manual placement and enables assembly rates exceeding 5,000 components per hour on modern placement equipment, significantly improving throughput for high-volume PCB production runs compared to tube-packaged alternatives.
In what high-density applications does the Tiger Eye contact design outperform standard receptacle contacts?
Tiger Eye contacts, used in the TFC-133-02-FM-D-A-K-TR, provide a dual-beam wiping action that maintains reliable electrical contact through thousands of mating cycles and in the presence of mild oxidation or contamination. This makes them preferable to single-beam contacts in test and measurement fixtures, backplane daughter-card systems, and removable module applications where mating cycle counts exceed 500 and contact resistance must remain below 30 milliohms.
When should an engineer select the TFC-133-02-FM-D-A-K-TR over a higher-pitch 0.100 inch connector for the same 66-position requirement?
Selecting the TFC-133-02-FM-D-A-K-TR at 0.050 inch pitch over a 0.100 inch alternative reduces the connector footprint by approximately 75%, freeing significant PCB real estate in compact embedded modules. The tradeoff is a lower per-pin current rating, typically around 1 A per pin at 0.050 inch pitch versus 3 A at 0.100 inch, so the TFC-133 is the right choice when signal density matters more than high-current capacity.
