Crystals Procurement Notes

Verify the specific suffix 'D' against official TXC documentation to confirm the exact load capacitance and stability grade, as variations exist within the 9C series. Ensure the HC-49/US footprint matches the target PCB layout. Confirm RoHS compliance status through current datasheets, as manufacturing updates may occur. Cross-reference the manufacturer part number with distributor listings to avoid confusion with similar HC-49S variants.

Crystals Selection Notes

Select this component when a standard 24 MHz reference is required with moderate stability and wide temperature coverage. The HC-49/US SMD package offers a balance between traditional reliability and modern assembly methods. Consider the 22 pF load capacitance requirement for circuit matching. Evaluate the 30 Ohm ESR against oscillator driver strength requirements to ensure reliable startup conditions in the target application.
