Crystals Procurement Notes

Verify the specific load capacitance and ESR requirements against the target circuit design before procurement. Confirm that the 4-SMD footprint matches the board layout constraints. Ensure the supply chain source provides original manufacturer documentation to guarantee compliance with RoHS standards and lead-free processing compatibility.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required in high-density electronic assemblies. Consider the 100 ohm ESR limit to ensure proper oscillator circuit startup conditions. Evaluate the 5 ppm/year aging rate against long-term system timing accuracy requirements. Compare physical dimensions against available board real estate to confirm fitment within the designated SMD area.

Crystals Part Context

This part belongs to the ILCX13 series of surface-mount crystals from ILSI America. The series is characterized by small footprints and reliability for portable electronics. Similar parts in the lineup include variants with different frequencies such as 12 MHz or 24 MHz, sharing the same mechanical package and general electrical specifications while differing in resonant properties.

Crystals Replacement Considerations

Direct substitutes may include other 40 MHz SMD crystals with identical 10 pF load capacitance and comparable ESR limits. Verify pinout compatibility and physical dimensions to ensure interchangeability without redesigning the PCB footprint.
