18QHTF21-28.630-PD is listed in the Oscillators range at ChipApex. The manufacturer field lists Mercury Electronics Ind. Co. Ltd. Its product description is 28.63 MHz XO 1.8V 2.0X1.6 MM PD. Review the specifications below when checking this part for your BOM.
The 18QHTF21-28.630-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 28.630 MHz. It utilizes LVCMOS output logic and functions with a supply voltage of 1.8V. The component features a standby or power-down capability for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, designed for surface-mount applications requiring precise timing signals.
Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 2.0x1.6 mm SMD package dimensions to prevent assembly issues during manufacturing.
Select this component when a low-voltage 1.8V supply is available and space constraints require a 2.0x1.6 mm footprint. The LVCMOS output is suitable for standard digital logic families. Consider the power-down feature if battery life or thermal management is a priority in the application environment.
This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The series includes various frequencies and packages, catering to diverse timing needs in consumer and industrial electronics. Mercury Electronics has established itself as a supplier of crystals and oscillators since 1973.
Direct substitutes include other 18QHTF21 variants with different frequencies, such as 18QHTF21-25.000-PD or 18QHTF21-32.768-PD, provided the frequency difference is acceptable. Cross-brand replacements must match the 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package constraints.
