Procurement Notes

Verify the specific suffix METV-T against official QST documentation to confirm the exact load capacitance and stability specifications, as variations exist within the QT325S family. Ensure compatibility with the target circuit's load capacitance requirements before procurement. Cross-reference the datasheet for precise electrical parameters and thermal characteristics to avoid integration issues.

Selection Notes

Select this component when a compact, glass-sealed crystal with ±10 ppm stability is required for 24 MHz applications. Consider the 8 pF load capacitance requirement for circuit design alignment. Evaluate the 3.2x2.5 mm footprint against available board space. Compare ESR values with other options if power consumption is a critical constraint in the application.
