Frequently Asked Questions
What contact finish does the SMS-125-01-S-D use, and how does it affect mating reliability?
The SMS-125-01-S-D features gold (30 µin) over nickel (50 µin) contact plating, providing excellent corrosion resistance and stable contact resistance below 20 mΩ across hundreds of mating cycles. This finish is ideal for high-reliability board-to-board connections in industrial and telecom equipment requiring long service life.
How many positions does the SMS-125-01-S-D provide, and what is its body length?
The SMS-125-01-S-D is a dual-row socket connector with a 1.25-inch body length and 0.335-inch body depth, accommodating 50 pins total across both rows. This pin count and footprint make it suitable for high-density signal and power routing on standard pitch PCB layouts.
When should a design engineer choose the SMS-125-01-S-D over a single-row alternative for backplane applications?
For backplane or mezzanine applications requiring more than 25 signals in a constrained footprint, the dual-row SMS-125-01-S-D offers 50 pins within a 1.25-inch length, effectively halving board space compared to a single-row solution. Its robust gold-plated contacts support signal integrity demands at data rates up to several hundred MHz.
Is the SMS-125-01-S-D RoHS compliant and available for quick shipment?
Yes, the SMS-125-01-S-D carries full RoHS compliance with a Pb-free designation, making it suitable for eco-conscious product builds. Through SAMTEC's Tiger Buy program it carries a 1-week factory lead time and is stocked at distributors globally, enabling fast delivery with worldwide shipping options.
