Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 3.3V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for any specific environmental ratings if operating in extreme conditions.

Oscillators Selection Notes

Select this component when a low-frequency, standard precision oscillator is required. The LVCMOS interface suits digital logic circuits directly. Consider the enable pin utility for power-sensitive designs. Compare against other Mercury models if different frequencies or voltages are needed.

Oscillators Part Context

This part belongs to the 3QHTF21 series from Mercury Electronics, a supplier of quartz crystals and oscillators. The series typically offers various frequencies within a small form factor. Mercury has been manufacturing frequency control products since 1973, focusing on Taiwan-based production for global markets.

Oscillators Replacement Considerations

Direct substitutes may include other 4.71859 MHz LVCMOS oscillators in 4-SMD packages. Verify electrical parameters such as current consumption and startup time. Cross-reference with similar Mercury series parts like 25QHTF21 variants if voltage differences are acceptable.
