Crystals Procurement Notes

Verify that the specific suffix FF3F18 corresponds to the required 25 MHz frequency and ±30 ppm tolerance before ordering. Confirm compatibility with lead-free soldering profiles as the device is RoHS compliant. Ensure the 18 pF load capacitance matches the oscillator circuit design requirements to maintain accurate frequency performance.

Crystals Selection Notes

Select this component when a small footprint is critical for space-constrained designs such as mobile phones or wireless LAN devices. The 25 MHz frequency is suitable for general clock generation where moderate stability is sufficient. Consider the 80 Ω ESR limit to ensure proper drive level matching within the target application circuit.

Crystals Part Context

This part belongs to the ILCX18 series, which offers ultra-miniature packages ranging from 12 MHz to 80 MHz. The series is characterized by low cost and small package footprints, making it ideal for portable consumer electronics. ILSI America manufactures these components to support high-volume production needs in the global frequency control market.

Crystals Replacement Considerations

No public confirmed substitute part numbers are available in the provided documentation. Cross-referencing requires matching the 25 MHz frequency, 18 pF load capacitance, 80 Ω ESR, and 2.5x2.0 mm package dimensions.
