18QHTF21-3.1872-OE is listed in the Oscillators range at ChipApex. The manufacturer field lists Mercury Electronics Ind. Co. Ltd. Its product description is 3.1872 MHz XO 1.8V 2.0X1.6 MM OE. Review the specifications below when checking this part for your BOM.
The 18QHTF21-3.1872-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 3.1872 MHz with an LVCMOS output signal. The device requires a 1.8V supply voltage and features enable/disable functionality for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. The unit supports an operating temperature range of -40°C to 85°C and maintains a frequency stability of ±50ppm.
Verify the specific suffix against official Mercury Electronics documentation to confirm electrical characteristics and pinout compatibility. Ensure the selected variant matches the required supply voltage and frequency tolerance for the target application design.
Select this component when a small footprint and low voltage operation are critical. The LVCMOS output is suitable for digital logic interfaces. Confirm that the ±50ppm stability meets the system clock requirements before integration.
This part belongs to the Mercury Electronics 18QHTF21 series of surface mount oscillators. The series offers various frequencies and voltage options within a standardized 2.0x1.6 mm package, providing designers with flexible timing solutions for portable and industrial applications.
Direct substitutes include other 18QHTF21 series variants from Mercury Electronics with matching frequency and voltage specifications. Cross-brand replacements require verification of pinout, voltage, and output type compatibility.
