Microcontroller oscillator circuits

Procurement Notes

Verify the specific suffix codes against official manufacturer documentation to confirm exact electrical parameters and packaging configurations. Ensure that the requested part number matches the required load capacitance and stability ratings for the target application environment. Cross-reference datasheet revisions to confirm material compliance and manufacturing status before finalizing procurement orders.

Selection Notes

Select this component when a surface mount solution is required for 18.432 MHz applications. Consider the HC-49/US form factor for space-constrained layouts. Evaluate the ±50ppm stability requirement against system timing budgets. Confirm thermal operating ranges align with the intended environmental conditions to ensure long-term reliability.

Part Context

This model belongs to the QT49S series of quartz crystals produced by QST. The series encompasses various frequencies and package types, including both through-hole and surface mount variants. The MAGQ suffix indicates specific electrical and mechanical characteristics distinct from other series members.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Verify cross-compatibility with existing inventory only through direct manufacturer datasheet comparison.
