Procurement Notes

Verify the specific suffix requirements against the target application's environmental constraints. Confirm that the 4-SMD footprint matches the PCB layout guidelines precisely. Ensure compatibility with standard reflow soldering profiles for this package type. Cross-reference the load capacitance requirements with the host circuit design to maintain frequency accuracy.

Selection Notes

Select this component when a 37.5 MHz base mode crystal is required in a small form factor. Consider the ±50ppm stability specification relative to system jitter requirements. Evaluate the 40 Ohm ESR against the oscillator circuit's drive level limitations. Compare the 12pF load capacitance with existing designs to avoid impedance mismatch issues.

Part Context

This part belongs to the QT532S series of quartz crystals manufactured by QST. The series offers various frequencies and package options for embedded applications. The QT532S designation indicates a specific size and pin configuration distinct from other QST crystal families. It serves as a fundamental timing element in digital electronics requiring precise clock sources.

Replacement Considerations

Direct substitutes include parts with identical 37.5 MHz frequency, 12pF load capacitance, and 4-SMD no lead packaging. Verify that alternative components meet the same ±50ppm stability and -40°C to +85°C temperature range specifications. Ensure the replacement maintains the 40 Ohm ESR characteristic for circuit compatibility.
