Crystals Procurement Notes

Verify the specific load capacitance requirement of 18 pF against the target circuit design to ensure frequency accuracy. Confirm that the PCB footprint matches the 5x3.2 mm SMD package dimensions. Ensure the application environment remains within the specified -40°C to +85°C operational range. Check for RoHS compliance documentation if required by regulatory standards. Validate the series resistance value of 40 Ohms for proper oscillation startup conditions.

Crystals Selection Notes

Select this component when a 25 MHz reference is required for surface-mount designs. Consider the ±30 ppm stability for general-purpose timing applications. Evaluate the 18 pF load capacitance compatibility with the host oscillator circuit. Compare physical size constraints against alternative packages like the 3225 variant. Assess thermal requirements against the specified operating temperature limits.

Crystals Part Context

This part belongs to the C3E series of quartz crystals from Aker Technology. It is distinct from other series such as C5S or C2E which may offer different frequencies, package sizes, or electrical characteristics. The C3E series typically focuses on standard surface-mount form factors suitable for consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes include C3E-25.000-18-3030-X-R from the same manufacturer. Verify pinout and dimensional compatibility before substitution.
