- Low-power embedded systems
Procurement Notes
Verify the exact frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail is stable and meets the datasheet specifications. Confirm that the PCB footprint matches the 4-SMD No Lead package dimensions provided in the official documentation to avoid assembly issues.
Selection Notes
Select this component when a low-frequency clock signal near 1.163 MHz is required for synchronous data transfer or timing references. Consider the 1.8V operating voltage constraint and ensure compatibility with downstream logic levels. The small form factor makes it ideal for space-constrained designs where standard through-hole oscillators cannot fit.
Part Context
This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on miniature surface-mount crystal oscillators. The series is characterized by its small footprint and low power consumption, targeting modern portable electronics. Mercury Electronics has been a supplier of frequency control products since 1973, providing quartz-based timing solutions.
