Crystals Procurement Notes

Verify the specific package dimensions and lead configuration against the official datasheet to ensure compatibility with automated pick-and-place equipment. Confirm that the load capacitance requirements of the host circuit align with the 12.5 pF specification to maintain accurate frequency performance. Check for any specific handling instructions regarding electrostatic discharge sensitivity during storage and assembly processes.

Crystals Selection Notes

Select this component when a standard 32.768 kHz reference is required for timekeeping functions. Consider the ±20 ppm initial tolerance and ±3 ppm/year aging rate for applications demanding moderate long-term accuracy. Ensure the 2-SMD footprint matches the printed circuit board layout constraints. Evaluate the 80 kOhms series resistance limit to confirm it meets the drive level requirements of the connected oscillator circuit.

Crystals Part Context

This part belongs to the family of surface-mount crystals manufactured by YIC International. These components are engineered to provide reliable frequency generation for digital systems. The 32.768 kHz output is a standard choice for dividing down to one-second intervals in binary counters. The product line emphasizes consistency in electrical parameters across production batches.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, 12.5 pF load capacitance, and 2-SMD no-lead package type. Verify that alternative sources offer comparable ±20 ppm tolerance and similar physical dimensions to ensure mechanical fit. Cross-reference series resistance values to prevent overdriving the new component.
