Frequently Asked Questions
What pin count and pitch does the TFM-142-12-LM-D-A-P-TR provide for high-density interconnect designs?
The TFM-142-12-LM-D-A-P-TR offers 84 positions in a dual-row layout at .050" (1.27 mm) pitch, enabling high-density signal routing in a footprint roughly half the size of comparable 2.54 mm pitch connectors, making it ideal for FPGA mezzanine cards and compact embedded computing modules.
How does the Tiger Eye contact design in the TFM-142-12-LM-D-A-P-TR improve reliability compared to standard socket contacts?
The Tiger Eye contact system applies a consistent normal force across the mating interface, maintaining contact resistance below 20 milliohms over thousands of mate-unmate cycles, which is critical for high-cycle test fixtures, reconfigurable avionics modules, and other applications where connector wear is a long-term concern.
What do the A and P suffixes in TFM-142-12-LM-D-A-P-TR indicate, and why are they important for PCB assembly?
The A suffix designates an alignment post and the P suffix adds a polarization feature, together ensuring the connector seats correctly during automated pick-and-place assembly and preventing a 180-degree mismatement error that could damage 84 signal pins or reverse power supplies on populated boards.
