Crystals Procurement Notes

Verify the specific package dimensions and pinout configuration against the official datasheet before integration. Confirm that the load capacitance requirements of the target circuit match the 12.5 pF specification to ensure accurate frequency stability. Check for any specific handling instructions regarding electrostatic discharge during storage and assembly.

Crystals Selection Notes

Select this component when a precise 32.768 kHz reference is required for low-power timing applications. The ±20 ppm tolerance provides adequate accuracy for most real-time clock functions. Ensure the PCB layout supports the specific surface mount footprint to maintain mechanical integrity and electrical performance.

Crystals Part Context

This part belongs to the TFA series of tuning fork crystals, which are widely used for timekeeping in portable electronics. The 32.768 kHz frequency is chosen because it divides evenly into one second using binary counters. This series offers a balance between size, power consumption, and frequency stability for embedded designs.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, ±20 ppm tolerance, and 12.5 pF load capacitance. Verify that alternative manufacturers offer compatible SMD footprints. Cross-reference pin configurations if the replacement uses a different lead arrangement.
