Crystals Procurement Notes

Verify the specific suffix 'IJT' against official CTS documentation to confirm lead frame material and termination plating specifications. Confirm that the 9pF load capacitance matches the target oscillator circuit design requirements. Check current availability status as distribution channels may list obsolete or discontinued stock variants. Ensure compliance with project-specific environmental regulations such as RoHS3 and REACH before final procurement approval.

Crystals Selection Notes

Select this component when a compact SMD footprint is required alongside tight frequency stability constraints. The 120 Ohm ESR value must be compatible with the driving circuit's oscillation conditions to ensure reliable startup. Consider the 9pF load capacitance requirement carefully to avoid frequency pulling issues in the final assembly. Evaluate thermal performance needs against the specified -40°C to +85°C operational range for the intended environment.
