Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. 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 reliable assembly and long-term performance.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6mm form factor makes it ideal for dense PCB layouts where space is limited. Consider the power-down feature if battery life or thermal management is a critical design constraint. Ensure the operating temperature range meets the environmental conditions of the target application.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal and oscillator products. The company has decades of experience in frequency control solutions. The 'PD' suffix typically indicates the inclusion of a power-down pin or function, distinguishing it from standard continuous-operation oscillators within the same family.
