Frequently Asked Questions
What are the contact finish specifications for the TMM-102-03-S-S mating and termination interfaces?
The TMM-102-03-S-S features gold (30 µin) plating on the mating contacts for low-resistance, reliable connections, while the termination side uses matte tin (Sn) with a nickel (Ni) barrier layer. This combination supports robust soldering and long-term conductivity across thousands of mating cycles.
How compact is the TMM-102-03-S-S, and which board-space-constrained designs can it fit?
The TMM-102-03-S-S has a body length of 0.158 inch, breadth of 0.079 inch, and depth of 0.059 inch, making it one of SAMTEC's low-profile connector options. These 4-pin dimensions suit tight PCB layouts in industrial controls, embedded computing, and handheld electronics where vertical clearance is under 2 mm.
Is the TMM-102-03-S-S RoHS compliant, and what is its typical lead time?
Yes, the TMM-102-03-S-S is fully RoHS compliant and Pb-free. SAMTEC lists a factory lead time of 1 week, and it is available from distributor stock worldwide, making it practical for both prototype builds requiring quick turnaround and higher-volume production runs of 100 or more units.
In which connector categories does the TMM-102-03-S-S compete, and when is it preferred over taller vertical headers?
The TMM-102-03-S-S is a vertical board connector (Header, Vertical category) with only 4 positions and a body depth of 0.059 inch. It is preferred over taller alternatives when board stack height must remain below 3 mm, such as in wearables, compact sensor modules, or PCIe riser cards with strict profile budgets.
