Procurement Notes

Verify the complete part number including suffixes against official QST documentation to ensure correct frequency and tolerance specifications. Confirm package type and load capacitance requirements match circuit design needs. Check RoHS compliance status if required by project regulations. Validate supplier authenticity through authorized channels to prevent counterfeit components.

Selection Notes

Select this component when a 36 MHz reference with ±30 ppm stability is required within the -20°C to +70°C range. Ensure the circuit design supports a 12 pF load capacitance. Consider the 4-SMD no-lead package for automated assembly processes. Verify that the operating environment remains within the specified temperature limits to maintain frequency accuracy.

Part Context

This model belongs to the QT325G series of surface-mount crystals from QST. The series provides various frequency options with standardized mechanical dimensions. The MAAE suffix indicates specific electrical characteristics including the 36 MHz frequency and ±30 ppm stability rating. These components are commonly used in consumer electronics and industrial equipment requiring stable clock signals.

Replacement Considerations

Direct substitutes must match the 36 MHz frequency, 12 pF load capacitance, and ±30 ppm stability specification. Compatible packages include 4-SMD no-lead types with identical 3.2x2.5mm dimensions. Verify equivalent temperature range coverage and mounting compatibility before substitution.
