Frequently Asked Questions
What contact finish does the QTE-020-03-L-D use and how does it affect performance?
The QTE-020-03-L-D uses gold contact finish on the mating surface and tin over nickel on the termination side. Gold provides low contact resistance typically below 20 milliohms and resists oxidation across thousands of mating cycles, critical for high-reliability board stacking in server and telecom equipment.
How many positions does the QTE-020-03-L-D provide and what is its row configuration?
The QTE-020-03-L-D is a 40-position connector arranged in a dual-row configuration, providing 20 pins per row. This layout allows routing of up to 40 signals or mixed power and signal lines between two stacked PCBs within a compact footprint.
What is the ELP feature on the QTE-020-03-L-D and when is it beneficial?
ELP stands for Enhanced Latch Performance, a mechanical feature that improves retention force between mated connector halves. It prevents unintended disconnection in environments subject to vibration levels above 5 g, making the QTE-020-03-L-D suitable for industrial, automotive, and aerospace board stacking applications.
Is QTE-020-03-L-D compliant with RoHS and lead-free soldering requirements?
Yes, the QTE-020-03-L-D is fully RoHS compliant with a tin-over-nickel termination finish, which supports lead-free wave and reflow soldering processes at temperatures up to 260 degrees C. This makes it compatible with modern eco-friendly PCB assembly lines across all major markets.
