Crystals Procurement Notes

Verify the specific suffix designation against official documentation to confirm exact electrical parameters and packaging specifications. Ensure compatibility with the target circuit's load capacitance requirements before integration. Confirm that the selected variant meets the necessary industrial temperature standards for the intended deployment environment.

Crystals Selection Notes

Select this component when a 25 MHz reference with ±30 ppm stability is required within a -40°C to +85°C operational window. The 10 pF load capacitance specification must align with the host oscillator circuit design. Consider the 4-pin SMD form factor for space-constrained board layouts where glass-sealed reliability is prioritized over standard ceramic packages.

Crystals Part Context

This part belongs to the 7R series of surface-mount quartz crystals from TXC Corporation. The series is characterized by its use of glass-sealing techniques to improve long-term frequency stability and environmental resilience compared to traditional ceramic-packaged alternatives, making it suitable for demanding electronic applications.

Crystals Replacement Considerations

Cross-reference with other 25 MHz crystals featuring 10 pF load capacitance and similar dimensional constraints. Verify that any substitute maintains the required ±30 ppm stability and supports the specified -40°C to +85°C temperature range without altering the circuit's oscillation conditions.
