Frequently Asked Questions
What pitch and row count does the TFM-125-01-S-D-RA use for board stacking?
The TFM-125-01-S-D-RA uses a 1.27 mm pitch in a dual-row configuration, providing 50 positions total for dense signal and power routing in board stacking applications. This tight pitch allows the connector to fit within compact PCB footprints while maintaining reliable electrical performance at standard logic voltages.
How does the contact finish of TFM-125-01-S-D-RA improve mating reliability?
The TFM-125-01-S-D-RA features 30 µin gold plating over 50 µin nickel on the mating contacts, which significantly reduces contact resistance and guards against oxidation over repeated mating cycles. The matte tin with nickel barrier termination finish ensures strong solder joint reliability on the PCB landing pads.
Which applications benefit from the right-angle orientation of the TFM-125-01-S-D-RA?
The right-angle (RA) version of TFM-125-01-S-D-RA is ideal for applications where two PCBs must mate at a 90-degree angle, such as daughter-card-to-backplane interfaces in industrial computing, test equipment, or rack-mounted systems. The 1.27 mm pitch and 50-position count support routing dozens of 3.3 V or 5 V signals in a minimal board area.
What is the typical lead time for the TFM-125-01-S-D-RA and is it RoHS compliant?
The TFM-125-01-S-D-RA has a factory lead time of 1 week, making it suitable for time-sensitive procurement needs. It is fully RoHS compliant, with a Pb-free designation, so it meets environmental regulations for electronics manufacturing in the EU and other regions requiring lead-free components.
