18QHTF21-10.250-PD

Overview

The 18QHTF21-10.250-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.25 MHz and utilizes LVCMOS output logic. The device is powered by a 1.8V supply voltage and features a Standby (Power Down) control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes Standby (Power Down) functionality for power management
• Utilizes a compact 4-SMD, No Lead surface-mount package

Applications

• General-purpose timing clock generation
• Digital signal processing systems
• Embedded controller circuits

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 footprint matches your PCB layout constraints to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the Standby feature if power conservation during idle periods is a priority for the application design.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-sized crystal oscillators. The series typically offers various frequencies and voltage options within a consistent 2.0x1.6 mm package. The 'PD' suffix indicates the inclusion of a Power Down pin for standby control.

Replacement Considerations

Direct substitutes must match the 10.25 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and thermal characteristics before swapping.
