18QHTF21-10.1386-OE

Overview

The 18QHTF21-10.1386-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.1386 MHz and utilizes LVCMOS output logic levels. The device is designed for low-voltage applications, functioning at 1.8V. It features an Enable/Disable control pin for power management flexibility. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm, suitable for space-constrained surface-mount designs.

Feature Summary

• LVCMOS output interface for digital compatibility
• Integrated enable/disable functionality for power control
• Compact 4-SMD no-lead surface mount package

Applications

• Portable electronic devices requiring low voltage operation
• Embedded systems utilizing LVCMOS logic families
• Communication modules needing precise clock timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD footprint matches your PCB layout constraints. Cross-reference the OE suffix to confirm the enable pin configuration matches your schematic requirements.

Selection Notes

Select this component when a low-profile, low-voltage clock source is required for LVCMOS-compatible circuits. Consider the 1.8V operating range if power efficiency is critical. The small 2.0x1.6mm package makes it suitable for dense layouts. Verify that the enable pin feature is necessary for your power management strategy compared to always-on alternatives.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control solutions. The manufacturer has decades of experience in producing crystals and oscillators. This series typically offers standard XO performance in miniature packages, targeting modern consumer electronics and computing applications where size and power consumption are key factors.

Replacement Considerations

Direct replacements must match the 10.1386 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Check datasheets for equivalent parts from other manufacturers offering similar form factors and electrical characteristics. Ensure the replacement supports the enable/disable function if required by the design.
