Crystals Procurement Notes

Verify the exact package dimensions and pin configuration against the official manufacturer datasheet before integration. Confirm that the load capacitance requirement matches the oscillator circuit design to ensure accurate frequency performance. Ensure compliance with RoHS regulations if required by your product specifications. Cross-reference the part number suffixes to confirm availability of specific testing or packaging options.

Crystals Selection Notes

Select this component when a fundamental mode crystal is required for 40 MHz applications with moderate stability needs. The 8 pF load capacitance suits standard oscillator designs. Consider the 60 Ohm ESR for impedance matching. Evaluate thermal requirements against the -40 °C to +85 °C operating range. Compare with overtone crystals if higher frequency stability or lower phase noise is necessary for the specific application.
