Frequently Asked Questions
How many positions and rows does the TFM-121-03-LM-D-RA provide, and what is its pitch?
The TFM-121-03-LM-D-RA is a dual-row connector with 42 total positions arranged on a 0.050 inch (1.27 mm) pitch, allowing high-density signal routing in compact PCB layouts without sacrificing contact reliability.
What orientation does the TFM-121-03-LM-D-RA use, and how does that affect PCB layout choices?
This connector uses a right-angle (RA) orientation, which means the mating direction is parallel to the PCB surface. This is advantageous for edge-accessible interconnections or when vertical clearance is limited, saving at least several millimeters of stack height compared to vertical headers.
In which types of embedded or industrial designs is the TFM-121-03-LM-D-RA a suitable choice?
The TFM-121-03-LM-D-RA suits backplane, mezzanine, and daughtercard assemblies in industrial control, test instrumentation, and embedded computing. Its 42-position, 0.050 inch pitch layout supports 42 signal lines in a footprint under 55 mm long, making it practical for space-constrained enclosures.
