18QHTF21-3.319507-PD

Oscillators Overview

The 18QHTF21-3.319507-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 3.319507 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• Supports low-voltage operation with integrated standby functionality
• Delivers standard LVCMOS output signals for digital interfacing
• Utilizes a lead-free surface-mount package design

Oscillators Applications

• General-purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a stable 3.319507 MHz reference is required for low-power digital systems. The LVCMOS interface ensures compatibility with standard logic families. Consider the 1.8V operating voltage if power efficiency is a priority. The small form factor makes it suitable for space-constrained designs where traditional through-hole oscillators cannot fit.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic, which specializes in frequency control products. The series typically offers various frequencies within a standardized package family. Mercury Electronics has been a pioneer in the crystal industry since 1973, providing reliable timing solutions for global electronics markets.

Oscillators Replacement Considerations

Direct substitutes must match the 3.319507 MHz frequency, LVCMOS output, and 1.8V supply voltage. Check for identical 4-SMD, No Lead package dimensions to ensure board compatibility. Verify that any alternative component meets the same temperature range and stability specifications as the original Mercury part.
