Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliability.

Oscillators Selection Notes

Select this component when a small form factor and low power consumption are critical. The LVCMOS output is suitable for standard digital logic families. Consider the operating temperature range if the device will be used in extreme environments. Compare performance metrics such as phase noise and stability against other oscillators in the same series to ensure it meets the application's timing accuracy needs.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. The 'PD' suffix indicates the inclusion of a power-down pin or feature. These oscillators are designed to replace larger through-hole components in modern miniaturized electronics, providing reliable timing solutions for high-density circuit boards.

Oscillators Replacement Considerations

Direct substitutes within the same series include models with identical package sizes and voltage levels but different frequencies, such as 18QHTF21-30.300-PD or 18QHTF21-51.200-PD, provided the frequency difference is acceptable for the application. Verify pinout compatibility and electrical specifications before swapping.
