Crystals Procurement Notes

Verify the specific suffix 'R' against official manufacturer documentation to confirm tape and reel packaging requirements. Ensure the selected variant matches the required 18 pF load capacitance and 70 Ohm ESR specifications for circuit compatibility. Cross-reference the -20°C to 70°C operating temperature range with application environmental constraints before finalizing procurement orders.

Crystals Selection Notes

Select this component when an 8 MHz reference is required for surface-mount applications with moderate frequency stability needs. The 18 pF load capacitance must align with the oscillator circuit's external capacitor values. Consider the 70 Ohm series resistance for drive level sensitivity and ensure the 4-pin footprint matches the target PCB design guidelines.
