18QHTF21-27.0016-PD

Oscillators Overview

The 18QHTF21-27.0016-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 27.0016 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby (power down) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. This component is designed for applications requiring precise timing signals within low-power electronic systems.

Oscillators Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features a standby mode to enable power down capabilities
• Utilizes a leadless SMD package for surface mount assembly

Oscillators Applications

• General purpose clock signal generation
• Low power embedded systems
• Digital circuit timing references

Oscillators Procurement Notes

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

Oscillators Selection Notes

Select this model when a 27.0016 MHz frequency is required alongside LVCMOS signaling standards. Consider the 1.8V operating voltage constraint and the availability of standby functionality for power-sensitive designs. Evaluate the physical size constraints of the 2.0x1.6mm package against available board space. Compare performance metrics such as phase noise and stability if specified in official documentation.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics Ind. Co. Ltd. The series typically offers various frequencies and voltage options within similar small form factors. Mercury Electronics is a manufacturer specializing in frequency control products, including quartz crystals and oscillators, with a history dating back several decades in Taiwan.

Oscillators Replacement Considerations

Direct substitutes may include other models from the same 18QHTF21 series with different frequencies or voltages, provided the pinout and package dimensions remain identical. Cross-referencing with other manufacturers requires careful verification of electrical parameters and mechanical fit.
