Crystals Procurement Notes

Verify the specific suffix requirements against the official CTS datasheet to ensure compatibility with target load capacitance and tolerance levels. Confirm that the selected variant matches the required operating temperature range and package dimensions for the intended PCB layout. Cross-reference the manufacturer part number with authorized distributors to validate authenticity and current production status before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 25 MHz fundamental crystal with ±15ppm stability is required for space-constrained designs. The 8pF load capacitance specification must align with the host circuit's oscillator design parameters. Ensure the -10°C to +60°C operating range meets the environmental conditions of the application. The 100 Ohm ESR value should be compatible with the driving circuit capabilities to ensure reliable oscillation startup.

Crystals Part Context

This part belongs to the CTS 402 Series, which covers a frequency range of 16MHz to 60MHz. The series utilizes standard SMD crystal technology suitable for high-volume manufacturing. The 402F250XXCKR specifically addresses the need for compact, cost-effective frequency control solutions in consumer and industrial electronic devices where moderate stability and small form factors are prioritized.

Crystals Replacement Considerations

Direct parameter-equivalent substitutes may include other 25 MHz 4-SMD crystals from CTS or alternative manufacturers with matching 8pF load capacitance and similar physical dimensions. Verify that any replacement maintains the same ESR characteristics and operating temperature range to ensure circuit compatibility without redesign.
