Crystals Procurement Notes

Verify the specific suffix FF5F10 against official ILSI documentation to confirm exact electrical parameters such as load capacitance and ESR. Ensure compatibility with lead-free assembly processes if required by the manufacturing environment. Cross-reference the 25 MHz frequency requirement with circuit design specifications to validate oscillator loop conditions and drive level constraints before final procurement.

Crystals Selection Notes

Select this component when a 25 MHz reference is required in a compact surface-mount footprint. The 10 pF load capacitance must match the oscillator circuit design. Consider the 80 ohm ESR limit for power consumption requirements. Verify that the ±30 ppm tolerance meets system timing accuracy needs. Ensure the operating temperature range covers the intended environmental conditions.

Crystals Part Context

This part belongs to the ILCX19 series of ultra-miniature ceramic package quartz crystals manufactured by ILSI America. The series offers various frequencies and tolerances in a standardized 2.0mm x 1.6mm SMD form factor. These components are designed for high-volume consumer and industrial electronics requiring precise timing references in space-constrained applications.

Crystals Replacement Considerations

Direct substitutes within the ILCX19 series may exist with different suffixes indicating varied tolerances or load capacitances. Verify pinout and dimensional compatibility before substitution. Consult ILSI official documentation for cross-reference lists to ensure electrical parameter equivalence.
