Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official part number guide to ensure correct load capacitance and tolerance specifications. Confirm that the procurement channel provides original manufacturer documentation to validate authenticity. Check for updated lead times as manufacturing schedules may vary. Ensure compatibility with reflow soldering profiles specified in the datasheet to prevent mechanical stress on the ceramic body during assembly processes.

Crystals Selection Notes

Select this component when a small form factor is required alongside moderate frequency stability. The 6 pF load capacitance suits circuits with low parasitic capacitance. Consider the 90 kOhm ESR for oscillator circuit design to ensure adequate loop gain. Evaluate thermal requirements against the -40°C to +85°C operating range. Compare against higher tolerance variants if stricter aging or initial accuracy is needed for the application.
