Procurement Notes

Verify the specific suffix 'MAAJ' against official QST documentation to confirm exact tolerance and stability ratings. Ensure the ordering part number matches the required 50MHz frequency and 18pF load capacitance specifications. Cross-reference the package dimensions and operating temperature range with design requirements before procurement.

Selection Notes

Select this component when a 50MHz clock source is required for surface-mount PCB designs. Consider the ±30ppm stability and 50Ω ESR for circuit compatibility. Evaluate the 5x3.2mm package size against available board space constraints. Confirm that the -20°C to +70°C operating range meets the environmental conditions of the target application.

Part Context

This model belongs to the QT532S series of quartz crystals from QST. The series offers various frequencies and packages for general-purpose timing applications. The QT532S-50.000MAAJ-T specifically provides a 50MHz output in a standard small outline package, suitable for consumer and industrial electronics requiring precise clock signals.

Replacement Considerations

Compatible substitutes include other 50MHz SMD crystals with similar 18pF load capacitance and ±30ppm stability. Verify pin compatibility and mechanical dimensions before substitution. Check manufacturer datasheets for equivalent performance characteristics.
