Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 2.0x1.6 mm footprint matches the PCB layout constraints. Check for any specific handling instructions regarding ESD sensitivity during assembly processes to maintain component integrity.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V LVCMOS oscillator is required for high-density boards. Consider the 30.19 MHz frequency specifically if it matches the input requirements of the downstream processor or communication interface. Evaluate the standby feature necessity for power management strategies. Compare physical dimensions against available board real estate to ensure fitment within the designated area.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, designed for general-purpose clock generation. The 18QHTF21 prefix indicates a specific family of small-footprint oscillators.
