18QHTF21-33.333-PD

Oscillators Overview

The 18QHTF21-33.333-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 33.333 MHz with LVCMOS output logic and a supply voltage of 1.8V. The device features a Standby (Power Down) function and is housed in a 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic for digital interfacing.
• Includes a Standby or Power Down mode to reduce power consumption when inactive.
• Utilizes a compact 4-SMD No Lead surface-mount package design.

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply requirement aligns with the target circuit design. Ensure the 4-SMD No Lead package footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component for applications requiring a precise 33.333 MHz timing source with low voltage operation. The choice is driven by the need for LVCMOS compatibility and the space constraints addressed by the small 2.0x1.6mm package. Consider the standby feature if power management is a priority in the final product design.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies within a standard 1.8V LVCMOS format. The series is characterized by its small form factor and power-down capability, catering to modern portable and compact electronic devices requiring reliable clock signals.

Oscillators Replacement Considerations

Direct substitutes must match the 33.333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar XO specifications in the same footprint to ensure functional equivalence.
