Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Ensure the operating temperature range aligns with the system environment. Confirm that the 1.8V supply voltage matches the target circuit design to prevent malfunction or damage during operation.
Selection Notes
Select this component when a low-profile surface-mount oscillator is required for 1.8V logic systems. Consider the 4-SMD package size for space-constrained PCB layouts. Verify that the LVCMOS output swing is compatible with the receiving input thresholds of the connected digital components to ensure signal integrity.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series typically offers various standard frequencies in small form factors. Mercury Electronics has a long history in Taiwan manufacturing quartz crystals and oscillators, providing reliable timing solutions for electronic industries.
Replacement Considerations
Check for direct substitutes within the same series, such as 18QHTF21 variants with different frequencies. Ensure any replacement maintains the 1.8V supply, LVCMOS output, and 4-SMD package dimensions. Verify pinout compatibility if substituting with similar packages from other manufacturers.
