Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure exact electrical parameter alignment. Confirm that the package variant matches the required PCB land pattern. Check for any recent updates to the RoHS compliance status or material declarations. Ensure the supplier provides valid traceability documentation for Class III life-supporting device requirements if applicable to the end application.

Crystals Selection Notes

Select this component when a small form factor quartz crystal is required for portable audio or wireless systems. The 32 MHz frequency and 10 pF load capacitance are standard for many microcontroller clock inputs. Consider the ±10 ppm tolerance sufficient for general timing applications where high precision is not critical. Evaluate the 60 Ohm ESR against the oscillator circuit drive level specifications to prevent over-driving.
