18QHTF21-27.027-OE is listed in the Oscillators range at ChipApex. The manufacturer field lists Mercury Electronics Ind. Co. Ltd. Its product description is 27.027 MHz XO 1.8V 2.0X1.6 MM OE. Review the specifications below when checking this part for your BOM.
The 18QHTF21-27.027-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.027 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package suitable for surface-mount applications.
Verify the specific ordering suffix to confirm the enable/disable feature and voltage level. Ensure the 4-SMD no-lead package dimensions match the target PCB footprint. Confirm that the 1.8V supply requirement aligns with the system design before procurement.
Select this component when a 27.027 MHz clock source with active low-power control is required. Consider the 1.8V operating voltage constraint against available system rails. Evaluate the small form factor against space limitations in the target assembly.
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series includes various frequencies and packages, with this specific model offering standard performance characteristics for general electronic applications.
Direct substitutes within the same series include variants with different frequencies such as 18QHTF21-37.888-OE or 18QHTF21-27.040-OE, provided the frequency difference is acceptable for the application.
