Crystals Procurement Notes

Verify the specific revision status, such as Rev A3, when sourcing components to ensure compatibility with current manufacturing standards. Confirm that the supplier provides official datasheets matching the part number exactly. Check RoHS compliance documentation if required by your project regulations. Ensure storage conditions align with MSL Level 1 requirements to prevent moisture-related damage during soldering processes.

Crystals Selection Notes

Select this component for applications requiring stable 25 MHz timing in harsh environments. The low ESR specification makes it suitable for direct connection to microcontroller Ethernet peripherals without additional driving circuitry. Consider the 18 pF load capacitance when designing PCB traces to account for parasitic effects. This model is appropriate for projects demanding long-term frequency accuracy over extended operational lifespans.
