Crystals Procurement Notes

Verify the specific suffix 'D' against the original design specification, as it may denote a particular tolerance or packaging variant distinct from other series members like 'E'. Confirm that the 18pF load capacitance matches the target circuit's oscillator requirements to ensure accurate frequency generation. Check RoHS3 compliance status if environmental regulations apply to the final product assembly.

Crystals Selection Notes

Select this component when a 25 MHz reference is required in a compact 3.2x2.5mm footprint. Ensure the application circuit can support the specified 60 Ohm ESR and 18pF load capacitance. Consider the ±30ppm initial tolerance and ±50ppm total stability limits against the system's timing accuracy requirements. Verify compatibility with standard surface-mount reflow processes given the no-lead package type.
