Crystals Procurement Notes

Verify that the specific suffix IH1F18 corresponds to the required 13.56875 MHz frequency, ±15 ppm tolerance, and 18 pF load capacitance. Confirm the manufacturer designation matches ILSI America LLC rather than other vendors who may use similar nomenclature. Ensure the ordering information aligns with the official datasheet parameters for the ILCX13 series before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 13.56875 MHz reference is required for RF or communication interfaces. The 18 pF load capacitance must match the oscillator circuit design. The 100 Ω ESR limit is critical for ensuring proper oscillation startup. Verify that the 0°C to +70°C operating temperature range meets the environmental requirements of the target application.

Crystals Part Context

This part belongs to the ILCX13 series of ultra-small quartz crystals from ILSI America. The series is characterized by its small footprint and high performance, designed specifically for modern electronic devices where space is limited. The ILCX13 line supports various frequencies and packages, providing a standardized solution for frequency control in consumer electronics and wireless applications.

Crystals Replacement Considerations

Cross-reference with ILCX13-FF5F18 variants if different tolerance or stability ratings are acceptable. Verify compatibility with alternative suppliers offering identical 3225 SMD packages and 13.56875 MHz frequencies. Ensure any substitute maintains the same 18 pF load capacitance and 100 Ω ESR limits.
