18QHTF21-1.024-OE

Overview

The 18QHTF21-1.024-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.024 MHz and utilizes LVCMOS output logic levels. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• Integrates LVCMOS output interface for digital signal compatibility
• Features active enable/disable pin for low-power operation control
• Utilizes small form factor SMD package for space-constrained designs

Applications

• Portable electronic devices requiring low power consumption
• Embedded systems needing precise clock synchronization
• Consumer electronics with limited board space

Procurement Notes

Verify the specific suffix OE indicates the enable function against official datasheets. Confirm the 1.8V operating voltage matches system requirements. Ensure the 4-SMD footprint aligns with PCB layout specifications before ordering.

Selection Notes

Choose this component when a 1.024 MHz reference is required with low voltage operation. Consider the enable feature if power saving during idle states is necessary. Verify thermal performance within the small package constraints.

Part Context

Mercury Electronic Ind. Co., Ltd. is a Taiwan-based manufacturer specializing in quartz crystals and oscillators since 1973. This part belongs to their standard XO series, offering reliable timing solutions for various industrial and consumer applications.

Replacement Considerations

Check for direct substitutes from Mercury Electronics with identical frequency and package. Verify compatible alternatives from other manufacturers only if pinout and electrical characteristics match exactly.
