18QHTF21-2.034-PD

Oscillators Overview

The 18QHTF21-2.034-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 2.034 MHz and utilizes LVCMOS output logic. The device is designed for low voltage applications with a supply voltage of 1.8V. It features a power-down capability via standby mode. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Provides stable clock signals using quartz crystal technology
• Supports low voltage operation at 1.8V supply
• Includes power-down functionality for energy management

Oscillators Applications

• General purpose clock signal generation
• Low voltage digital circuit timing
• Portable electronic devices requiring power efficiency

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this component when a precise 2.034 MHz reference is required for LVCMOS-compatible logic families. Consider the 1.8V operating voltage constraint and the need for power-down control. Evaluate the small 2.0x1.6mm form factor against available board space. Compare performance against other Mercury oscillators if different frequencies or package sizes are needed.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies and supports LVCMOS outputs. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the same physical package family.

Oscillators Replacement Considerations

Direct substitutes must match the 2.034 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Consult manufacturer cross-reference lists for equivalent parts from other vendors offering identical electrical and mechanical specifications.
