18QHTF21-24.003-PD

Oscillators Overview

The 18QHTF21-24.003-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 24.003 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for timing applications requiring precise clock signals in space-constrained electronic systems.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V for efficient power consumption
• Includes standby and power-down functionality to reduce current draw when inactive
• Provides stable LVCMOS output signals for digital circuit synchronization

Oscillators Applications

• Battery-powered portable devices requiring low current consumption
• Compact consumer electronics with limited board space
• Digital communication systems needing precise clock timing

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 4-SMD no-lead package footprint matches the PCB design requirements. Ensure the 1.8V supply rail is stable within the specified limits to maintain signal integrity. Check for any RoHS compliance documentation if required for your manufacturing standards.

Oscillators Selection Notes

Select this component when a small form factor is critical due to its 2.0x1.6mm size. Choose it for applications where power efficiency is prioritized, given the 1.8V supply and standby capabilities. Consider it for designs requiring LVCMOS compatibility with existing digital logic levels. Evaluate the need for a power-down feature to extend battery life in portable products.
