Overview
The 18QHTF21-1.611-PD is a surface-mount crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.611 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and features a compact 4-SMD, No Lead package, specifically a 4-VDFN (3.2x2.5) configuration. It includes a standby or power-down function for energy management. The component is designed for applications requiring precise timing signals in portable electronics.
Feature Summary
- Compact 4-SMD surface mount package design
- LVCMOS output logic compatibility
- Integrated standby power-down capability
Applications
- Portable electronic devices
- Battery-powered equipment
- General purpose clock generation
Procurement Notes
Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply requirement aligns with your system's power rails. Ensure the 4-VDFN footprint matches your PCB layout constraints. Check for any RoHS compliance documentation if required by your manufacturing standards.
Selection Notes
Select this component when a low-frequency, high-stability clock source is needed for battery-operated systems. The 1.8V operation makes it suitable for modern low-voltage digital circuits. Consider the small form factor for space-constrained designs. Evaluate the standby feature benefits for power-sensitive applications compared to continuous-operation oscillators.
Part Context
This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Industrial Co., Ltd. The series is characterized by its transition to surface-mount technology and expanded frequency ranges. Mercury has been a pioneer in frequency control products since 1973, offering quartz-based solutions including crystals and spread-spectrum oscillators.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided data. Cross-reference with other Mercury 18QHTF21 variants only if frequency and voltage match exactly.
