Procurement Notes

Verify the specific suffix 'GV' against official QST documentation to confirm exact electrical parameters and package details, as distributor listings may vary. Ensure compatibility with the target circuit's load capacitance requirements before procurement. Cross-reference the part number with the manufacturer's latest datasheet to confirm availability and compliance status.

Selection Notes

Select this component when a 30 MHz crystal with ±30 ppm tolerance and ±50 ppm stability over -40°C to +85°C is required. Consider the 18 pF load capacitance and 3.2x2.5mm package size for PCB layout constraints. Compare ESR values against the oscillator circuit design specifications to ensure proper startup conditions.

Part Context

The QT325G series represents QST's line of surface-mount crystals. Variants within this series differ primarily in frequency, tolerance codes, and package dimensions. This specific model belongs to the 30 MHz subset, sharing common physical characteristics with other frequencies in the same package family while differing in electrical performance metrics.

Replacement Considerations

Direct substitutes include other 30 MHz SMD crystals with matching 18 pF load capacitance and similar dimensional constraints. Verify that alternative parts meet the ±30 ppm tolerance and ±50 ppm stability requirements over the specified temperature range to maintain system timing integrity.
