18QHTF21-7.382-PD

Overview

The 18QHTF21-7.382-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.382 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Feature Summary

• LVCMOS output logic interface
• Integrated standby and power-down functionality
• Surface-mount 4-SMD no lead package

Applications

• General clock signal generation
• Embedded system timing
• Consumer electronics

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the PCB footprint matches the 4-SMD no lead package dimensions to guarantee proper assembly and electrical connection during manufacturing.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside standard LVCMOS compatibility. The inclusion of a power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the small form factor if space constraints are a primary design driver.
