Crystals Procurement Notes

Verify the exact load capacitance specification against the official datasheet, as conflicting data sources indicate values of either 20 pF or 24 pF for this part number. Confirm that the intended application circuit matches the required load capacitance to ensure accurate oscillation frequency. Check current availability status directly with authorized distributors, as stock levels fluctuate frequently.

Crystals Selection Notes

Select this component when a 20 MHz fundamental frequency with ±30 ppm stability is required for surface-mount applications. Ensure the design accommodates the 5.0 x 3.2 mm footprint and the specific thermal environment limits of -20°C to +70°C. Verify compatibility with the target oscillator circuit's drive level requirements before finalizing the selection.

Crystals Part Context

This component belongs to the 445 series of quartz crystals manufactured by CTS-Frequency Controls. The series offers various frequencies and packages optimized for standard surface-mount assembly processes. It serves as a passive frequency-determining element in electronic systems requiring precise clock generation without active oscillator circuitry.

Crystals Replacement Considerations

Direct substitutes include other 20 MHz SMD crystals from the same manufacturer with identical electrical parameters and mechanical dimensions. Cross-referencing with equivalent parts from other suppliers requires strict verification of load capacitance, ESR, and physical footprint compatibility.
