Crystals Procurement Notes

Verify the specific frequency tolerance requirement against the datasheet specification of ±20 ppm, as some listings may reference different tolerances. Confirm the load capacitance matches the circuit design requirements of 18 pF. Ensure the 4-SMD no-lead package dimensions align with the PCB footprint constraints. Check for RoHS compliance confirmation if required by project regulations. Validate the manufacturer part number directly with authorized distributors to ensure authenticity.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency is required with moderate stability. The 18 pF load capacitance must match the external circuit loading. Consider the ±20 ppm tolerance for applications requiring tighter frequency accuracy than standard ±30 ppm parts. The wide temperature range suits industrial environments. Verify that the series resistance of 100 Ω is compatible with the driving circuit's power limits.

Crystals Part Context

This part belongs to the C3E series of surface-mount crystals from Aker Technology Corp. The series offers various frequencies and package sizes. The C3E-25.000-18-2030-R specifically denotes the 25 MHz variant with 18 pF load capacitance. It is distinct from other series like C5S which may have different dimensional profiles or electrical characteristics.

Crystals Replacement Considerations

Direct substitutes include other 25 MHz SMD crystals with 18 pF load capacitance and similar package dimensions. Cross-reference with equivalent parts from other manufacturers ensuring matching frequency tolerance and temperature range. Verify pin compatibility and mounting footprint before substitution.
