Crystals Procurement Notes

Verify the specific suffix configuration against official manufacturer documentation to ensure correct load capacitance and tolerance specifications. Confirm that the selected variant matches the required operating temperature range and drive level parameters for the target circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a compact 25 MHz timing source is required for space-constrained portable electronics. Ensure the application circuit provides the specified 8 pF load capacitance to maintain accuracy. Verify that the system drive level does not exceed 1 µW to prevent frequency instability or mechanical damage to the resonator element.

Crystals Part Context

This part belongs to the 7A series of SMD glass-sealed crystals from TXC Corporation. These components are engineered for high reliability in environmental performance. The series utilizes lead-containing sealing glass, which is exempted under current RoHS directives. This specific model represents a standard commercial-grade solution for general-purpose clock generation.

Crystals Replacement Considerations

Cross-reference alternative 25 MHz SMD crystals with identical 8 pF load capacitance and ±30 ppm tolerance. Ensure substitute parts match the 2.5 x 2.0 mm footprint and support the same -40 °C to +85 °C operating range. Verify compatibility with existing PCB layout constraints.
