Crystals Procurement Notes

Verify the specific suffix code against the manufacturer's official frequency code table to confirm exact electrical parameters, as generic part numbers may represent multiple variants. Ensure compatibility with the target circuit's load capacitance requirements before procurement. Cross-reference the datasheet for moisture sensitivity level and reflow soldering profile compliance to prevent component damage during assembly.

Crystals Selection Notes

Select this component when a 25 MHz fundamental frequency with ±15 ppm stability is required in a compact 4-SMD footprint. Consider the 100 Ohm ESR value for oscillator circuit design to ensure sufficient loop gain. Evaluate the -20°C to +70°C operating range against environmental conditions. Compare against alternative packages if space constraints differ from the 2.00mm x 1.60mm dimension.

Crystals Part Context

This part belongs to the 402 series of SMD crystals from CTS-Frequency Controls. The series offers various frequencies and packages for general-purpose timing needs. The 402F250XXCDR specifically addresses applications requiring a 25 MHz output in a small form factor. It serves as a passive frequency control element in electronic assemblies.

Crystals Replacement Considerations

Consult the official CTS Frequency Code Table for direct substitutes with identical electrical specifications. Verify pinout and dimensional compatibility for any cross-brand replacements. Ensure the substitute maintains the same load capacitance and ESR values to avoid oscillator startup issues.
