18QHTF21-3.000-OE

Oscillators Overview

The 18QHTF21-3.000-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 3.000 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. It supports an operating temperature range from -40°C to 85°C and offers a frequency stability of ±50ppm.

Oscillators Feature Summary

• Supports active enable and disable control for power management
• Generates LVCMOS output signals compatible with digital logic interfaces
• Utilizes a surface-mount package optimized for space-constrained designs

Oscillators Applications

• Embedded systems requiring precise timing references
• Consumer electronics utilizing low-voltage microcontrollers
• Industrial control modules operating within extended temperature ranges

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Ensure that the 1.8V supply rail can maintain stable voltage under all operating conditions to prevent frequency drift. Confirm that the PCB footprint matches the 4-SMD no-lead package dimensions provided in the official datasheet to ensure proper soldering and mechanical retention.

Oscillators Selection Notes

Select this component when a low-profile, low-voltage oscillator is required for 3 MHz applications. Consider the ±50ppm stability specification relative to system clock accuracy needs. Evaluate the thermal performance within the -40°C to 85°C range if the application involves environmental extremes. Compare the enable/disable functionality against simple on/off switching requirements to determine if power-saving features are necessary for the specific product lifecycle.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically includes various frequencies and voltage options, such as 3.3V variants or different frequency outputs like 6.3 MHz. The 'OE' suffix indicates the presence of an output enable pin, distinguishing it from parts without control features. This family is designed for general-purpose timing applications in portable and industrial devices.

Oscillators Replacement Considerations

Direct replacements must match the 3.000 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify compatibility of the enable/disable pin configuration. Parts like the 18QHTF21-3.1815-OE share the same package but differ in frequency.
