Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your system design before ordering. Confirm that the 1.8V supply voltage aligns with your target platform's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to avoid assembly issues during manufacturing.

Oscillators Selection Notes

Choose this model when a low-profile, low-voltage oscillator is required for space-constrained designs. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency is critical. Verify thermal performance within the specified operating temperature range for reliable long-term operation in your application environment.

Oscillators Part Context

This part belongs to the 18QHTF series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and voltages. The 'PD' suffix indicates the inclusion of a power-down capability. These components are widely used in portable devices where size and power consumption are primary design drivers.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 models with identical pinout and electrical characteristics but different frequencies, such as 18QHTF21-30.300-PD or 18QHTF21-80.000-PD, provided the frequency difference is acceptable for the system clock requirements.
