Crystals Procurement Notes

Verify the specific suffix 'DR' indicates tape and reel packaging configuration as per manufacturer documentation. Confirm that the 18pF load capacitance matches the target circuit design requirements. Ensure the ±20ppm stability specification meets the system timing accuracy constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20.48 MHz fundamental mode crystal is required in a compact SMD form factor. The 18pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 100 Ohm ESR limit for oscillator startup reliability. The wide temperature range makes it suitable for industrial applications requiring consistent performance across varying thermal conditions.
