Overview
The 18QHTF21-10.040-OE is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 10.04 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes enable/disable functionality. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable and disable control capability
- Surface-mount construction with no lead design
Applications
- General purpose clock signal generation
- Digital system timing references
- Embedded controller clock sources
Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the part number suffix to confirm the exact variant specifications provided by the manufacturer.
Selection Notes
Select this component when a low-voltage, surface-mount oscillator with enable control is required. The LVCMOS output suits digital logic families operating at 1.8V. Consider the package size for space-constrained designs. Verify thermal performance within the specified operating temperature range for your application environment.
Part Context
This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The company has decades of experience in manufacturing crystals and oscillators. This series represents their standard XO offerings with integrated enable features.
Replacement Considerations
Direct substitutes include other 10.04 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Check pinout compatibility and electrical parameters carefully. Equivalent parts must support enable/disable functionality if required by the design.
