Crystals Procurement Notes

Verify the specific suffix and tolerance requirements against the target circuit design before procurement. Confirm that the 10 pF load capacitance matches the microcontroller or oscillator input specifications. Check for end-of-life status as discontinuation notifications may apply to this series. Ensure RoHS compliance documentation aligns with regional regulatory requirements for the final product assembly.

Crystals Selection Notes

Select this component when a 33.333333 MHz reference is required for digital communication interfaces. The 3225 package size suits space-constrained portable electronics. Consider the ±30 ppm tolerance sufficient for general consumer applications. Evaluate the 50 Ohm ESR against the driving circuit capabilities to prevent over-driving. Compare against ceramic packaged alternatives if superior moisture resistance is necessary for the operating environment.
