Crystals Procurement Notes

Verify current availability status as supply may be limited. Confirm that the HC-49/US package dimensions align with the target PCB layout. Ensure the 18pF load capacitance matches the oscillator circuit design requirements. Validate compliance with specific project environmental certifications prior to final procurement.

Crystals Selection Notes

Select this component when a standard 12 MHz reference is required for surface-mount designs. The HC-49/US form factor allows for direct replacement of through-hole variants without significant board modifications. Consider the ±10 ppm stability sufficient for general-purpose digital logic applications where high precision is not critical.
