18QHTF21-3.072-PD

Oscillators Overview

The 18QHTF21-3.072-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 3.072 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a power-down (standby) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode capability
• Utilizes LVCMOS output interface

Oscillators Applications

• Battery-powered portable devices
• Low-power consumer electronics
• Embedded timing circuits

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required frequency tolerance and load capacitance specifications. Confirm that the 1.8V supply requirement aligns with the target system's voltage rails. Check for RoHS compliance status if environmental regulations apply to the manufacturing process. Ensure the 4-SMD no-lead package footprint matches the PCB design constraints.

Oscillators Selection Notes

Select this component when a precise 3.072 MHz reference is needed for low-power applications. The 1.8V operating range makes it suitable for modern battery-operated systems where voltage efficiency is critical. Consider the small 2.0x1.6mm footprint for space-constrained designs. Verify that the LVCMOS output level is compatible with the receiving logic inputs of the connected microcontroller or processor.
