18QHTF21-3.333333-PD

Oscillators Overview

The 18QHTF21-3.333333-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 3.333333 MHz with an LVCMOS output interface. The device functions on a 1.8V supply voltage and features a standby mode for power down capabilities. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise clock signals.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Integrated standby function to reduce power consumption
• Compact 4-SMD no-lead package design

Oscillators Applications

• General purpose clock signal generation
• Embedded system timing references
• Consumer electronics circuit boards

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 package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 3.333333 MHz reference. Consider the LVCMOS output level compatibility with downstream digital circuits. Evaluate the physical size constraints of the 4-SMD package against available board space. Compare power consumption metrics if battery life is a critical design factor.

Oscillators Part Context

This part belongs to the QuikXO series from Mercury Electronics, which focuses on fast-delivery CMOS output clock oscillators. The series supports both standard and custom frequencies built to order. The 18QHTF21 model line represents a specific form factor within their broader portfolio of frequency control products established since 1973.

Oscillators Replacement Considerations

Direct substitutes must match the 3.333333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify pinout compatibility and thermal characteristics. Cross-reference with other Mercury QHTF series variants or equivalent industry-standard XO components offering identical electrical parameters.
