Crystals Procurement Notes

Verify the specific datasheet version for the 3X8-32.768K to confirm mechanical dimensions and soldering recommendations. Ensure that the load capacitance requirements of the target circuit align with the 12.5pF specification to maintain frequency accuracy within the ±20ppm tolerance. Confirm that the radial cylindrical can package fits the available PCB footprint and clearance constraints.

Crystals Selection Notes

Select this component when a compact, low-cost solution for precise timekeeping is required. The tuning fork architecture provides stability for clock generation tasks. Consider the radial package style if through-hole mounting is preferred over surface mount alternatives. Evaluate the ESR value against the oscillator circuit's drive level limitations to prevent over-driving the crystal.

Crystals Part Context

This part belongs to the family of miniature tuning fork crystals manufactured by Transko Electronics Inc. These components are distinct from standard parallel resonant crystals due to their specific geometry and high Q-factor, which makes them ideal for battery-powered devices where low power consumption and long-term stability are critical performance factors.

Crystals Replacement Considerations

Direct substitutes must match the 32.768 kHz frequency, ±20ppm tolerance, and 12.5pF load capacitance. Verify that alternative vendors offer the same radial cylindrical can package and -40°C to +85°C temperature rating to ensure mechanical and thermal compatibility.
