Crystals Procurement Notes

Verify the specific suffix codes against official Eaton documentation to confirm exact electrical tolerances and packaging configurations. Ensure that the selected variant matches the required load capacitance and frequency stability parameters for the target circuit design before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 20 MHz reference with ±10 ppm initial tolerance is required. Consider the 40 Ohm ESR and 12 pF load capacitance for oscillator circuit compatibility. Verify that the -40°C to +85°C operating range meets the environmental requirements of the intended application.

Crystals Part Context

This part belongs to the E3X series of surface-mount crystal resonators from Eaton Electronics. These components are designed for general-purpose timing applications where moderate stability and compact form factors are prioritized. The series offers various frequency options within standard industrial temperature ranges.

Crystals Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 12 pF load capacitance, 3225 package size, and ±10 ppm tolerance. Verify equivalent ESR and temperature stability characteristics. Consult manufacturer cross-reference lists for validated alternatives.
