Crystals Procurement Notes

Verify the specific suffix 'IJR' against manufacturer documentation to confirm package variant and tape/reel specifications. Ensure the target application circuit matches the 9pF load capacitance requirement to maintain frequency accuracy. Confirm that the 120 Ohm ESR limit aligns with the oscillator driver strength capabilities of the host device to prevent over-driving or failure to start.

Crystals Selection Notes

Select this component when a 16 MHz fundamental frequency with ±20ppm stability is required in a compact SMD form factor. The 9pF load capacitance specification dictates the necessary external capacitor values for the oscillator circuit. Consider the 120 Ohm ESR limit when evaluating power consumption and drive level constraints relative to other available crystal options in the 402 series.

Crystals Part Context

This part belongs to the CTS 402 Series, which offers various frequencies and packages for general-purpose timing needs. The 402F16022IJR specifically addresses the demand for 16 MHz reference clocks in space-constrained designs. It serves as a passive frequency-determining element within active oscillator circuits, providing the stable resonance necessary for digital logic synchronization.

Crystals Replacement Considerations

Direct substitutes must match the 16 MHz frequency, 9pF load capacitance, and 4-SMD (2.0x1.6mm) footprint. Verify that alternative parts meet the same ±20ppm stability and 120 Ohm ESR specifications to ensure circuit compatibility without redesign.
