Frequently Asked Questions
What is the pin count and pitch of the TFC-120-02-LM-D-A-K, and how is it arranged?
The TFC-120-02-LM-D-A-K has 40 positions in a dual-row layout with 20 contacts per row at a 1.27 mm (0.050") center-to-center pitch. This configuration supports 40 individual signal or power connections in a compact SMT footprint, suitable for high-density PCB interconnect applications.
What does the polarization key (K) option provide in the TFC-120-02-LM-D-A-K?
The polarization key (K) is a mechanical feature that physically prevents incorrect connector mating orientation. It ensures the mating plug can only be inserted in the correct direction, preventing reverse-polarity damage and reducing assembly errors in 40-position, 1.27 mm pitch dual-row interconnect systems.
How does lead-modified (LM) termination on the TFC-120-02-LM-D-A-K compare to standard FM termination for high-density boards?
Lead-modified (LM) termination features shaped leads with improved coplanarity tolerance compared to standard flat-mount (FM) termination, making it more forgiving on PCBs with slight warpage or surface irregularities. For a 40-position dual-row connector at 1.27 mm pitch, this improves reflow solder joint consistency across all 40 contacts and reduces the risk of cold joints in volume assembly.
