Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions. Confirm that the 1.8V supply rail is stable to maintain oscillator performance. Check for any specific reflow soldering profile recommendations provided in the official datasheet to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a compact form factor and low voltage operation are required. The 1.8V specification suits modern low-power digital circuits. The integrated power-down feature aids in battery-operated applications. Consider the 16.5 MHz frequency as suitable for specific baud rates or processor clocks. Verify compatibility with the target microcontroller's input voltage levels.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a small 2.0x1.6 mm package. These components are designed for high-volume consumer electronics. They provide a balance between size, power efficiency, and timing accuracy for portable devices.

Oscillators Replacement Considerations

Direct substitutes must match the 16.5 MHz frequency, 1.8V supply, and LVCMOS output. Compatible packages include 4-SMD no-lead types with identical 2.0x1.6 mm dimensions. Verify pinout compatibility if replacing with different manufacturers' parts. Ensure the replacement supports the same standby control functionality.
