Procurement Notes

Verify the specific suffix MEIQ-T against official QST documentation to confirm the exact frequency tolerance and temperature range specifications. Ensure compatibility with existing PCB footprints and soldering profiles before integration into production lines.

Selection Notes

Select this component when a 32 MHz reference is required with ±20 ppm stability over a wide industrial temperature range. Consider the 10 pF load capacitance requirement for circuit design alignment. Evaluate the glass seal technology for applications requiring robust environmental resistance compared to standard epoxy-sealed alternatives.

Part Context

This part belongs to the QT325S series of quartz crystals from QST, designed for general-purpose timing applications. The series offers various frequency options and stability grades, with the MEIQ-T variant specifically providing 32 MHz operation with defined thermal characteristics for industrial use cases.

Replacement Considerations

Cross-reference with other manufacturers offering 32 MHz SMD crystals with identical 3.2x2.5mm dimensions and 10pF load capacitance. Verify that substitute parts meet the same ±20 ppm stability and -40°C to +85°C operating range requirements.
