Crystals Procurement Notes

Verify the specific suffix FF5F10 against official ILSI documentation to confirm the 10 pF load capacitance requirement. Ensure the ordering part number matches the exact frequency tolerance and aging specifications required by the target circuit design. Confirm availability status as some variants in this series may be subject to manufacturing changes or obsolescence notices.

Crystals Selection Notes

Select this component when a 40 MHz reference signal is required for high-density surface-mount designs. The 10 pF load capacitance must match the oscillator circuit's external capacitor values. Verify that the 60 Ω maximum ESR is compatible with the driving capability of the host microcontroller or clock generator IC.

Crystals Part Context

This part belongs to the ILCX19 series, which provides ultra-miniature quartz crystals for space-constrained applications. The series utilizes a 4-pad ceramic package technology to support automated surface-mount assembly processes while maintaining high frequency stability for digital communication protocols.

Crystals Replacement Considerations

Direct substitutes require matching the 40 MHz frequency, 10 pF load capacitance, and 4-pin SMD footprint. Cross-reference with other manufacturers offering 2.0x1.6mm AT-cut crystals with identical electrical parameters to ensure pinout and mounting compatibility.
