Crystals Procurement Notes

Verify the specific load capacitance requirement of 18 pF against the target circuit design to ensure accurate oscillation. Confirm that the operating temperature range of -40 °C to +85 °C aligns with the environmental conditions of the final application. Ensure the physical footprint matches the available space on the printed circuit board layout.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required with a specific 18 pF load capacitance. Consider the 90 Ω ESR value for oscillator circuit compatibility. Evaluate the 5.0 x 3.2 mm package size against spatial constraints. Compare the ±15 ppm tolerance against system timing accuracy requirements.
