Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct packaging and compliance status. Confirm that the 18 pF load capacitance matches the target circuit design requirements. Check for any recent updates to the RoHS or REACH compliance declarations prior to final procurement authorization.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±20 ppm stability is required for space-constrained designs. The 30 Ohm ESR value must be compatible with the driving circuit's oscillation conditions. Ensure the PCB footprint accommodates the 5.00 mm x 3.20 mm dimensions and that the thermal environment remains within the specified -40°C to +85°C range.
