Crystals Procurement Notes

Verify the specific load capacitance requirement of your circuit against the 7 pF specification to ensure accurate oscillation. Confirm that the 80 Ohm ESR aligns with your oscillator circuit's drive level constraints. Ensure the 4-SMD footprint matches your board layout. Check for any specific handling requirements regarding electrostatic discharge during installation.

Crystals Selection Notes

Select this component when a precise 12.85761 MHz reference is required in a space-constrained environment. Consider the ±10 ppm tolerance if high stability over temperature is not critical. Evaluate the 7 pF load capacitance compatibility with your oscillator IC. Compare the 80 Ohm ESR against other available options to balance phase noise and startup time.
