18QHTF21-13.2719-PD

Overview

The 18QHTF21-13.2719-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 13.2719 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to reduce consumption during inactive periods. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS output compatibility
• Integrates a standby mode for effective power management
• Utilizes a lead-free 4-SMD surface-mount package design

Applications

• Embedded systems requiring precise clock synchronization
• Portable electronic devices utilizing low-power components
• Communication modules needing stable frequency generation

Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct configuration. Confirm that the required frequency tolerance and load capacitance match the target circuit design. Check for any regional compliance certifications relevant to the deployment location. Ensure the selected variant aligns with the intended operating temperature range for the final assembly.

Selection Notes

Choose this component when a 1.8V supply constraint exists alongside LVCMOS interface requirements. Evaluate the thermal performance needs against the specified operating temperature limits. Consider the physical footprint constraints of the PCB layout relative to the 4-SMD package dimensions. Assess whether the standby feature provides sufficient energy savings for the application profile.

Part Context

This model belongs to the 18QHTF21 series from Mercury Electronic, a manufacturer established in Taiwan specializing in quartz crystals since 1973. The series represents standard crystal oscillators designed for modern electronics. Mercury Electronic has decades of experience in frequency control products, positioning itself as a pioneer in the regional quartz industry.

Replacement Considerations

Cross-reference compatible parts within the same series, such as variants with different frequencies like 18QHTF21-19.680-PD or 18QHTF21-8.000-PD, if frequency adjustment is permissible. Verify pinout and electrical specifications before substituting with other manufacturers' offerings.
