Crystals Procurement Notes

Verify the specific suffix 'KR' against the manufacturer's official datasheet to confirm packaging configuration and exact electrical tolerances. Ensure the load capacitance requirement of the target circuit matches the 8pF specification. Confirm that the 100 Ohm ESR aligns with the oscillator circuit design parameters before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 12 MHz fundamental frequency is required with tight tolerance constraints. The 8pF load capacitance dictates compatibility with specific oscillator topologies. Consider the 3.2x2.5mm package size for PCB layout limitations. Validate that the ±10ppm tolerance meets the system's phase noise and jitter requirements for stable operation.

Crystals Part Context

This part belongs to the 403WF series of enhanced quartz crystals from CTS Corporation. The series targets modern embedded systems requiring high reliability in small form factors. The 403WF designation indicates a specific family of surface-mount resonators engineered for improved performance in digital communication and control applications compared to standard general-purpose crystals.

Crystals Replacement Considerations

The 403WF12012IMR is a related variant within the same series but specifies a different load capacitance of 4pF and potentially different ESR characteristics. Verify if the circuit can accommodate the 4pF load difference. Other 12MHz SMD crystals must be evaluated for matching package dimensions, ESR limits, and stability ratings to ensure functional equivalence.
