Procurement Notes

Verify the specific operating temperature range 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 2.0x1.6mm footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate the lead-free soldering profile compatibility during assembly.

Selection Notes

Select this model when a low-voltage 1.8V LVCMOS oscillator is required at 104.116 MHz. Consider the small 2.0x1.6mm package size for dense PCB layouts. Evaluate the need for a power-down feature to manage system power consumption. Compare performance against other Mercury Electronics XO series parts if different frequencies or voltages are needed. Ensure the standard output type meets the input requirements of the target device.

Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options within a standardized small outline package. It is designed for consumer electronics and industrial applications requiring reliable timing sources.
