18QHTF21-27.140-OE is listed in the Oscillators range at ChipApex. The manufacturer field lists Mercury Electronics Ind. Co. Ltd. Its product description is 27.14 MHz XO 1.8V 2.0X1.6 MM OE. Review the specifications below when checking this part for your BOM.
The 18QHTF21-27.140-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 27.14 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions corresponding to the SMD2016 form factor.
Verify the specific operating temperature range and load capacitance requirements against the target application circuit before procurement. Confirm that the 1.8V supply voltage aligns with the system power architecture. Ensure the SMD2016 footprint matches the PCB layout constraints. Cross-reference the datasheet for precise electrical characteristics to guarantee signal integrity.
Select this component when a low-voltage, small-footprint oscillator with control capabilities is required. The 27.14 MHz frequency suits specific data transmission standards. Consider the LVCMOS compatibility with downstream digital logic. Evaluate the enable pin utility for power-sensitive designs requiring dynamic clock gating.
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan's crystal industry. This series offers various frequencies within a standardized 4-SMD package, providing consistent mechanical and electrical profiles across different model variants.
Direct substitutes include other 18QHTF21 series models such as 18QHTF21-8.640-OE or 18QHTF21-37.888-OE if frequency adjustments are permissible. Verify that any replacement maintains the same 1.8V supply, LVCMOS output, and SMD2016 package dimensions to ensure board compatibility.
