Procurement Notes

Verify the specific ordering suffix to confirm the exact load capacitance, tolerance, and packaging format required for the design. Confirm RoHS compliance status and lead times directly with authorized distributors or IQD sales offices, as availability may vary by region. Ensure the selected variant matches the circuit's load capacitance requirements to maintain frequency accuracy.

Selection Notes

Select this component when a fundamental mode crystal with 11.0592 MHz frequency and 30 pF load capacitance is required. Ensure the application circuit supports the specified 500 µW drive level to prevent overdriving the crystal. Verify that the HC-49/4H package dimensions fit the mechanical constraints of the target assembly. Check that the ±50 ppm stability meets the system timing requirements across the intended temperature range.

Part Context

This part belongs to the IQD LFXTAL series of general-purpose quartz crystals. The series offers various frequencies and packages to support diverse electronic design needs. IQD Frequency Products provides timing solutions ranging from commercial grade to high-reliability industrial specifications, serving global markets for consumer, industrial, and communication electronics.

Replacement Considerations

Direct substitutes must match the 11.0592 MHz frequency, 30 pF load capacitance, HC-49/4H package, and similar ESR and drive level specifications. Cross-reference with other manufacturers' HC-49/U or HC-49/SMD variants if space permits, ensuring electrical compatibility.
