Crystals Procurement Notes

Verify the specific suffix requirements against the official datasheet to ensure compatibility with your circuit design. Confirm that the HC-49/U footprint matches your PCB layout constraints. Check RoHS compliance status if required by your manufacturing standards. Ensure the drive level specification aligns with your oscillator circuit to prevent overdriving the crystal element.

Crystals Selection Notes

Select this component when a 24 MHz reference frequency is required for through-hole applications. Consider the ±50 ppm stability requirement for timing accuracy needs. Evaluate the 20 pF load capacitance against your circuit's stray capacitance. Verify that the 20 Ohm ESR is compatible with your oscillator IC or gate requirements.
