Crystals Procurement Notes

Verify the specific suffix 'J' against official datasheets to confirm exact tolerance and stability ratings. Ensure the selected variant matches the required load capacitance of 18 pF for circuit compatibility. Confirm RoHS compliance status through current manufacturer documentation before integration into production environments.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for precise timing at 12.288 MHz. Consider the ±30 ppm stability requirement relative to system clock accuracy needs. Evaluate the 80 Ohm ESR against oscillator circuit drive level specifications to prevent over-driving or failure to start.
