Crystals Procurement Notes

Verify the specific datasheet version to confirm current manufacturing status, as some variants in this series may be obsolete. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm that the 40 Ohm ESR meets the oscillator circuit requirements for reliable startup. Check for any RoHS compliance documentation if required by assembly standards.

Crystals Selection Notes

Select this component when a 27 MHz reference is required in a small form factor. The 10 pF load capacitance must match the oscillator circuit design. Consider the ±30 ppm tolerance against environmental temperature variations. The 4-SMD package suits automated surface mount assembly processes. Evaluate the 100 µW drive level to prevent overdriving the crystal element.

Crystals Part Context

This part belongs to the ILCX19 series of surface mount crystals from ILSI. Similar models include the ILCX13 variant, which shares the 27 MHz frequency but differs in package type. Other frequencies in the series include 25 MHz and 26 MHz options. The FF5F10 suffix indicates specific electrical and mechanical characteristics within the product line.
