18QHTF21-18.100-PD

Oscillators Overview

The 18QHTF21-18.100-PD is a 18.1 MHz XO (Standard) LVCMOS Oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a supply voltage of 1.8V and features a Standby (Power Down) function. The component utilizes a 4-SMD, No Lead package with dimensions of 2.00mm x 1.60mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS output levels for digital interface compatibility
• Includes standby mode capability to reduce power consumption during inactive periods

Oscillators Applications

• Embedded systems requiring precise clock signals
• Portable electronic devices utilizing low voltage logic
• Communication modules needing standard frequency references

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V operating voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout design to prevent assembly issues.

Oscillators Selection Notes

Select this oscillator when a compact surface-mount solution is required for 18.1 MHz applications. Consider the 1.8V supply constraint and the necessity for a power-down feature. Evaluate the thermal and mechanical constraints associated with the small 2.00mm x 1.60mm package size for the intended enclosure.

Oscillators Part Context

This component belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequency options within a standardized small outline package format. The PD suffix indicates the inclusion of a power-down control pin or functionality.

Oscillators Replacement Considerations

Direct substitutes include other 18.1 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pinout compatibility and electrical specifications before swapping.
