18QHTF21-24.551-OE

Oscillators Overview

The 18QHTF21-24.551-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 24.551 MHz with an LVCMOS output interface. The device supports a supply voltage of 1.8V and features an enable/disable control function. It utilizes a base crystal resonator and offers a frequency stability of 50 ppm. The component is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm. Maximum supply current is specified at 22 mA.

Oscillators Feature Summary

• Integrates enable and disable functionality for power management
• Utilizes a no-lead surface mount design for compact integration
• Employs a base crystal resonator for stable frequency generation

Oscillators Applications

• High-performance digital signal processing systems
• Industrial commercial environments requiring wide temperature operation
• Clock source generation for embedded microcontrollers

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 footprint matches your PCB layout constraints. Cross-reference the manufacturer part number to avoid confusion with similar series components.

Oscillators Selection Notes

Select this component when a low-profile, 1.8V LVCMOS oscillator with enable control is required. Consider the 50 ppm stability for applications not demanding high precision. Evaluate the 2.0x1.6 mm package size against available board space. Compare against other Mercury Electronics models if different frequencies or voltage levels are needed.

Oscillators Part Context

This model belongs to the Mercury Electronics quartz crystal oscillator family. The company has produced frequency control products since 1973. The series includes various XO, TCXO, and VCXO types. This specific unit represents a standard frequency option within their surface-mount portfolio.

Oscillators Replacement Considerations

Direct substitutes include the 18QHTF21-30.0075-OE and 18QHTF21-21.200-OE from the same manufacturer. These share the same package and electrical interface but differ in operating frequency. Verify frequency compatibility before substitution.
