Crystals Procurement Notes

Verify the specific suffix 'ILT' corresponds to the tape-and-reel packaging configuration required for your assembly line. Confirm that the 100 Ohm ESR value matches your circuit design requirements to ensure proper startup and stability. Cross-reference the 12pF load capacitance with your system's external capacitor values to maintain the specified ±10ppm frequency accuracy.

Crystals Selection Notes

Select this component when a precise 20.48 MHz reference is needed in a constrained space. The ±10ppm stability offers higher precision than standard ±20ppm variants. Ensure the PCB footprint accommodates the 2.00mm x 1.60mm outline. Consider the fundamental mode operation if harmonic suppression is critical without additional filtering.

Crystals Part Context

This part belongs to the 402 Series of surface-mount crystals from CTS-Frequency Controls. The series provides various frequencies and packages optimized for high-volume manufacturing. The 402F20412ILT specifically targets applications requiring tight frequency tolerance in small form factors, distinguishing it from larger through-hole or older SMD designs.

Crystals Replacement Considerations

Direct substitutes include other 20.48 MHz crystals with identical 12pF load capacitance and similar ESR values. Verify pin compatibility and mechanical dimensions before swapping. Alternative suffixes may indicate different packaging or slightly varied tolerances; confirm datasheet alignment for electrical equivalence.
