Frequently Asked Questions
How many contact positions does the TSM-139-03-S-DV-P-TR have and what is the contact pitch?
The TSM-139-03-S-DV-P-TR features 78 positions arranged in a dual-row layout with a 0.100" (2.54 mm) pitch. This standard pitch allows compatibility with a wide range of mating connectors and simplifies PCB layout on standard 100-mil grid designs.
What current rating per pin does the TSM-139-03-S-DV-P-TR support, and is it suitable for power distribution rails?
Each pin of the TSM-139-03-S-DV-P-TR is rated for up to 3A of current, making it suitable for moderate power distribution applications. With 78 pins available, designers can dedicate multiple pins in parallel to carry higher aggregate currents on power rails in industrial or embedded systems.
Which PCB assembly process is compatible with the TSM-139-03-S-DV-P-TR — reflow, wave solder, or hand solder?
The TSM-139-03-S-DV-P-TR uses a surface mount (SMT) termination style that is compatible with standard reflow soldering processes. Its P-series variant also supports hybrid assembly, allowing wave soldering alongside through-hole components on the same board when process temperatures remain within the connector's rated thermal limits of up to 260°C peak reflow.
