Crystals Procurement Notes

Verify the specific suffix 'X-R' indicates tape and reel packaging when sourcing. Confirm that the 50 Ohm ESR matches the target oscillator circuit requirements. Ensure the -10°C to +70°C temperature range aligns with the operational environment constraints. Cross-reference the manufacturer part number against official distributor catalogs to confirm current availability status.

Crystals Selection Notes

Select this component for designs requiring a 12 MHz reference in a compact surface-mount form factor. The 20 pF load capacitance must match the external circuit loading. Consider the ±30 ppm tolerance for general timing accuracy needs. Verify compatibility with the host oscillator's drive level specifications to ensure stable operation without overdriving the crystal element.

Crystals Part Context

This part belongs to the CAA series of parallel fundamental crystals from Aker Technology Corp. It utilizes the HC-49/US footprint adapted for surface mounting. The series provides standardized frequencies for common digital logic and communication interfaces. The model designation encodes the frequency, load capacitance, tolerance, and packaging type.

Crystals Replacement Considerations

Direct substitutes include other 12 MHz SMD crystals with 20 pF load and similar ESR. Check mechanical dimensions for board space compatibility. Verify electrical parameters such as frequency tolerance and temperature stability before substitution.
