Frequently Asked Questions
How does the FLEXYZ contact technology in SQT-108-03-L-D benefit high-reliability designs?
The FLEXYZ contact technology in the SQT-108-03-L-D provides enhanced normal force compliance, ensuring consistent electrical contact across 16 positions even during thermal cycling from -55°C to +125°C. This reduces contact resistance variation and improves signal integrity in vibration-prone environments such as industrial and aerospace equipment.
What contact finish does the SQT-108-03-L-D use and why does it matter for mating reliability?
The SQT-108-03-L-D uses gold plating on its mating contacts, which provides corrosion resistance and low contact resistance typically under 20 milliohms. Gold finish is critical for applications requiring thousands of mating cycles without degradation, such as test sockets or frequently reconfigured modular boards with 16-position dual-row connectors.
Is the SQT-108-03-L-D suitable for automated SMT assembly processes?
The SQT-108-03-L-D is a through-hole board connector with a body depth of 0.25 inch and body length of 0.644 inch, making it compatible with automated insertion equipment rather than standard SMT reflow. Its 16-position dual-row pin-socket configuration requires through-hole PCB pads and wave or selective soldering for reliable board attachment.
