Crystals Procurement Notes

Verify the specific suffix 'C' indicates the cylindrical can variant when sourcing. Confirm that the 12.5 pF load capacitance matches the target oscillator circuit design. Ensure the through-hole footprint dimensions align with the PCB layout requirements. Check for RoHS compliance documentation if required by project specifications.

Crystals Selection Notes

Select this component when a through-hole tuning fork crystal is required for 32.768 kHz applications. The ±10 ppm tolerance provides higher accuracy than standard ±20 ppm parts. Consider the physical size constraints of the cylindrical can package during mechanical design. This part is suitable for designs prioritizing reliability over surface-mount convenience.

Crystals Part Context

This crystal belongs to the general category of 32.768 kHz tuning fork resonators used for timekeeping. Unlike surface-mount variants, the cylindrical can construction offers robust mechanical protection. It serves as a critical timing element in systems where long-term frequency stability is essential for accurate date and time tracking.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 12.5 pF load capacitance, and through-hole cylindrical package. Verify that replacement parts maintain the same ±10 ppm tolerance and ESR characteristics. Ensure the new component fits the existing PCB hole spacing and height restrictions.
