18QHTF21-13.050-OE

Overview

The 18QHTF21-13.050-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co. Ltd. It operates at a nominal frequency of 13.050 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 suitable for surface-mount applications.

Feature Summary

• LVCMOS output interface
• Enable/Disable control functionality
• Hermetic ceramic leadless SMD construction

Applications

• Timing and clock signal generation
• Electronic device synchronization
• General-purpose digital circuit timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official QHTF datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD No Lead package dimensions are compatible with the PCB footprint to prevent assembly issues.

Selection Notes

Select this component when a precise 13.050 MHz reference is required with low-voltage operation. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Consider the hermetic package for environments requiring robust environmental sealing compared to standard plastic packages.

Part Context

This part belongs to the QHTF series from Mercury Electronic, which offers various frequencies between 1.0 MHz and 200 MHz. The series provides multiple supply voltages and hermetic ceramic leadless SMD packages, establishing it as a versatile option for precision timing applications in industrial and commercial electronics.

Replacement Considerations

Consult the official QHTF datasheet for alternative part numbers within the same series that match the required frequency and voltage specifications. Direct substitutes must maintain the 4-SMD No Lead form factor and LVCMOS output characteristics to ensure mechanical and electrical compatibility.
