Frequently Asked Questions
How many positions does the TSM-139-02-LM-DV-P-TR have, and what is its contact pitch?
The TSM-139-02-LM-DV-P-TR has 78 positions arranged in 2 rows at a 2.54mm (0.100 inch) pitch. This dual-row configuration provides 39 contacts per row, supporting high-density signal routing on PCBs while maintaining compatibility with standard 0.100 inch grid spacing used across a wide range of backplanes and expansion boards.
What mounting style does the TSM-139-02-LM-DV-P-TR use, and how does this affect PCB assembly?
The TSM-139-02-LM-DV-P-TR uses surface mount (SMD) termination, allowing it to be placed by automated pick-and-place equipment and soldered during standard reflow processes. This eliminates the need for through-hole drilling and wave soldering, reducing PCB fabrication complexity and assembly cost for 78-pin connectors in production environments.
For which backplane or expansion card applications is TSM-139-02-LM-DV-P-TR a suitable connector choice?
This connector is well suited for PC/104 expansion headers, FPGA evaluation board I/O strips, and industrial backplane interfaces where 78 pins at 2.54mm pitch are needed. The dual-row SMD layout supports both signal and low-current power distribution across the 78 contacts, making it a practical choice for modular embedded computing and test-and-measurement expansion systems.
