Procurement Notes

Verify the specific suffix codes against official datasheets to ensure correct frequency, capacitance, and impedance values. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Cross-reference manufacturer part numbers with distributor listings to avoid ordering errors due to similar model names.

Selection Notes

Select this component when a cost-effective, space-saving solution is required for moderate precision timing needs. Ensure the system load capacitance matches the internal 33 pF specification. Consider the 30 Ohm impedance for driver compatibility. Evaluate thermal requirements against the -40°C to +85°C operational range before finalizing the design.
