Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a precise 16.777 MHz timing source is required for low-voltage digital circuits. Consider the LVCMOS output level if interfacing with 1.8V logic families. The small form factor makes it suitable for space-constrained portable devices or dense industrial control boards requiring reliable clock synchronization.

Oscillators Part Context

This part belongs to the 18QHTF21 series of quartz crystal oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6mm SMD package. These components are designed for applications needing stable clock signals with minimal power consumption and high reliability in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct substitutes must match the 16.777 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical specifications before swapping manufacturers.
