18QHTF21-16.608-PD

Oscillators Overview

The 18QHTF21-16.608-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 16.608 MHz and utilizes LVCMOS output logic levels. The device is designed for low voltage applications, functioning at a supply voltage of 1.8V. It features a standby or power-down mode capability to reduce energy consumption when not in active use. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm and a maximum height of 0.8mm, suitable for surface mount technology.

Oscillators Feature Summary

• Supports LVCMOS output interface for digital compatibility
• Includes standby (power down) functionality for power management
• Utilizes a compact 4-SMD no lead surface mount package

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication systems utilizing standard clock signals
• Embedded control circuits needing precise timing references

Oscillators 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 PCB footprint matches the 2.0mm x 1.6mm SMD package dimensions. Check for any specific reflow soldering profile recommendations provided by the manufacturer to ensure reliable assembly.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint oscillator is required for timing applications. Consider the LVCMOS output type if interfacing directly with digital logic inputs without additional buffering. Evaluate the power-down feature if battery life or thermal management is a critical constraint in the final product design.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on low-profile crystal oscillators. The series is characterized by its small 2.0x1.6mm package and support for various frequencies.
