Procurement Notes

Verify the specific package variant and tolerance grade required for your design before ordering. Confirm that the load capacitance matches the host circuit requirements to avoid frequency drift. Check for any specific handling instructions related to the ceramic or metal can packaging if applicable. Ensure the operating temperature range aligns with your environmental constraints. Cross-reference the datasheet revision to confirm electrical parameters have not changed.

Selection Notes

Select this component when a stable 32.768 kHz reference is needed for timekeeping functions. Consider the available package options such as SMD or through-hole variants based on board space constraints. Evaluate the required frequency tolerance and aging rate against the application's long-term accuracy needs. Ensure the drive level specifications are compatible with the oscillator circuit to prevent overdriving the crystal. Compare alternative packages from the same manufacturer for supply chain flexibility.
