Oscillators Procurement Notes

Verify the exact supply voltage and enable logic polarity against the official datasheet before procurement. Confirm the specific frequency tolerance and load capacitance requirements match the target circuit design. Ensure the package footprint aligns with the PCB layout specifications to prevent soldering defects during assembly.

Oscillators Selection Notes

Select this component when a low-profile, surface-mount oscillator with enable control is required. Consider the operating temperature range and frequency stability needs relative to the application environment. Compare pin compatibility and electrical characteristics with existing designs to ensure seamless integration without redesigning the host circuit board.

Oscillators Part Context

This part belongs to the 18QHT series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies and packages. The 18QHTF21 variant specifically denotes the form factor and output type. Similar parts include other frequencies within the same series such as 18QHTF21-30.0075-OE or different package variants like the 18QHTF22 series.

Oscillators Replacement Considerations

Direct replacements must match the 30.3 MHz frequency, LVCMOS output, and 4-SMD no-lead package. Verify that substitute components support the same enable/disable functionality and supply voltage range. Cross-reference pinouts to ensure compatibility with the existing footprint.
