18QHTF21-18.280-PD

Oscillators Overview

The 18QHTF21-18.280-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 18.28 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, no lead package suitable for surface-mount assembly.

Oscillators Feature Summary

• Supports low-voltage operation with 1.8V supply requirement
• Features LVCMOS output interface for digital compatibility
• Includes standby mode capability for power reduction

Oscillators Applications

• General purpose timing reference in electronic circuits
• Clock signal generation for digital systems
• Embedded system clock sources

Oscillators 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 no-lead package footprint matches your PCB layout constraints to avoid assembly issues.

Oscillators Selection Notes

Select this component when a precise 18.28 MHz clock source is required with low power consumption capabilities. Consider the LVCMOS output compatibility with your downstream logic family. Evaluate the thermal and mechanical constraints of the small SMD package within your enclosure design.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies while maintaining consistent electrical characteristics and packaging. The 'PD' suffix typically indicates the presence of a power-down feature, distinguishing it from standard continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 18.28 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical specifications before substituting.
