Frequently Asked Questions
What contact pitch and position count does the TFM-143-05-FM-D-LC offer for high-density layouts?
The TFM-143-05-FM-D-LC uses a 0.050 inch (1.27 mm) pitch and provides 86 positions in a dual-row (2x43) surface-mount configuration. This fine-pitch, high-count layout is suited for FPGA daughtercard, DSP module, and aerospace board stacking applications where maximizing pin density within a limited PCB area is essential.
What is the Tiger Eye contact technology and how does it improve connector reliability?
Tiger Eye is SAMTEC's proprietary contact design that features an additional wipe point for each contact, increasing the contact area and improving resistance to oxidation and debris. This results in lower and more consistent contact resistance over thousands of mating cycles, critical for high-reliability defense, aerospace, and instrumentation applications at 0.050 inch pitch.
How does the low-clearance (LC) termination of the TFM-143-05-FM-D-LC benefit stacked board assemblies?
The low-clearance termination style reduces the component height above the PCB surface, enabling tighter board-to-board stacking in multi-layer embedded systems. For designs where overall stack height must be minimized, the LC option on an 86-position, 0.050 inch pitch connector allows engineers to fit more functionality into compact enclosures without sacrificing connector reliability or signal density.
