Procurement Notes

Verify the specific ordering suffix and packaging configuration required for your production line, as availability may vary between bulk and reel formats. Confirm that the HC49/4HSMX package dimensions align with your PCB land pattern requirements. Ensure that the 18 pF load capacitance matches the oscillator circuit design parameters to achieve the specified ±30 ppm frequency accuracy. Check current supply status directly with authorized distributors or the manufacturer.

Selection Notes

Select this component when a 16 MHz surface-mount crystal with moderate stability is required. The HC49/4HSMX package offers a balance between size and mechanical robustness for SMD applications. Consider the 40 Ohm ESR value when designing the oscillator circuit to ensure reliable startup. This part is suitable for general industrial and consumer electronics where ±30 ppm stability over temperature is sufficient.
