Procurement Notes

Verify the specific suffix MEIJ-T against official QST documentation to confirm the exact stability and load capacitance specifications. Ensure compatibility with PCB footprint dimensions of 3.2x2.5mm. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components. Confirm that the required 18pF load capacitance matches the target circuit design parameters before finalizing procurement orders.

Selection Notes

Select this component when a 48 MHz surface-mount crystal with ±20 ppm stability is required. Ensure the application circuit supports an 18 pF load capacitance. Verify that the operating environment falls within the specified -40°C to +85°C range. Consider the physical size constraints of the 3.2x2.5mm package during layout planning.

Part Context

This part belongs to the QT325S series of surface-mount crystals from QST. The series offers various frequency options and stability grades. The MEIJ-T suffix denotes specific performance characteristics including the 48 MHz frequency, 18 pF load capacitance, and ±20 ppm stability profile suitable for general-purpose timing applications.

Replacement Considerations

Compatible substitutes include other 48 MHz SMD crystals with identical 3.2x2.5mm footprints and 18 pF load capacitance. Verify that alternative parts meet the ±20 ppm stability requirement across the -40°C to +85°C temperature range. Check equivalent ESR values to ensure circuit oscillation reliability.
