Procurement Notes

Verify the specific suffix 'MEIE' against the manufacturer's official datasheet to confirm the exact frequency tolerance and temperature range specifications. Ensure the selected variant matches the required load capacitance and stability parameters for the target application environment before finalizing procurement orders.

Selection Notes

Select this model when a small form factor is critical alongside moderate frequency stability requirements. The 3225 footprint allows for dense PCB layouts, while the ±20 ppm stability suits general-purpose timing needs. Consider higher precision variants if stricter phase noise or long-term aging performance is required for high-speed data interfaces.

Part Context

This component belongs to the QST QT325S series of thin-type ceramic packaged crystals. The series is engineered for applications demanding miniaturization without compromising environmental robustness. The glass-sealing technology distinguishes these parts from standard plastic-packaged alternatives, offering improved protection against humidity-induced frequency drift.

Replacement Considerations

Compatible substitutes include other 3225 SMD crystals with identical 25 MHz frequency, 12 pF load capacitance, and ±20 ppm stability. Verify that alternative manufacturers offer equivalent thermal stability ranges and mechanical dimensions to ensure direct pin-to-pin compatibility.
