Crystals Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical parameters and packaging configuration. Cross-reference the part number with current distributor listings to ensure availability status, as supply chain conditions may affect stock levels. Confirm that the intended application environment falls within the specified operating temperature range before finalizing procurement decisions.

Crystals Selection Notes

Select this component when a small footprint is required alongside moderate frequency stability specifications. The 18pF load capacitance must align with the oscillator circuit design to maintain accurate frequency performance. Consider the 60 Ohm ESR value relative to the driving capability of the host oscillator IC to prevent overdriving or startup failures during initial power cycles.
