Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer's official part number guide to confirm exact tolerance, stability, and packaging options. Ensure the selected variant matches the required load capacitance and ESR specifications for the target circuit design. Cross-reference the datasheet for any recent updates to electrical characteristics or mechanical dimensions before finalizing procurement orders.

Crystals Selection Notes

Select this component when a surface-mount solution matching the traditional HC-49/US outline is required. Consider the 18 pF load capacitance requirement for circuit compatibility. Evaluate the 120 Ohm ESR against the oscillator circuit's drive level limitations. Confirm that the ±15 ppm initial tolerance meets the system's frequency accuracy requirements.

Crystals Part Context

This part belongs to MMD's D Series of crystals, which offers flexible timing solutions supported by Abracon's global supply chain. The series provides various frequency options and package configurations to address diverse market needs. The DF18CC1 model specifically targets applications needing reliable surface-mount mounting while maintaining established footprint compatibility.

Crystals Replacement Considerations
