Crystals Procurement Notes

Verify the specific load capacitance and frequency tolerance requirements against the target circuit design before procurement. Confirm that the 4-SMD no-lead package dimensions align with the printed board layout. Ensure the operating temperature range meets the environmental conditions of the final application. Cross-reference the manufacturer datasheet for soldering profile recommendations to ensure component integrity during assembly processes.

Crystals Selection Notes

Select this component when a precise 40 MHz reference is required with tight initial tolerance. The 4 pF load capacitance must match the oscillator circuit's external capacitors. Consider the low series resistance for efficient drive level management. Evaluate the small form factor against available board space constraints. Verify compatibility with standard reflow soldering profiles used in surface mount assembly lines.

Crystals Part Context

This part belongs to Eaton's line of surface mount crystal resonators. These components are engineered for digital electronics requiring stable clock signals. The E2X series typically offers reliability in consumer and industrial applications. The specific model integrates quartz crystal technology into a standardized SMD package for automated manufacturing efficiency.

Crystals Replacement Considerations

Direct substitutes must match the 40 MHz frequency, 4 pF load capacitance, and 4-SMD package. Check equivalent parts from other manufacturers for identical electrical parameters. Verify pinout compatibility if alternative packages are considered. Ensure thermal performance specifications meet or exceed the original requirements.
