18QHTF21-3.600-PD

Oscillators Overview

The 18QHTF21-3.600-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a fixed frequency of 3.6 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes a standby function for power down capabilities. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• LVCMOS output interface
• Integrated standby mode
• Compact surface-mount form factor

Oscillators Applications

• General timing clock generation
• Embedded system synchronization
• Consumer electronics timing circuits

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints to avoid assembly issues.

Oscillators Selection Notes

Select this component when a low-voltage 3.6 MHz reference signal is required in space-constrained designs. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power management during idle states is a priority for the application.

Oscillators Part Context

This part belongs to the MiniSAS HD Series product range from Mercury Electronics, a supplier specializing in quartz crystals and oscillators. The manufacturer has been active in the frequency control industry since 1973, based in Taiwan. This series focuses on small-form-factor timing solutions.

Oscillators Replacement Considerations

Direct substitutes include other 3.6 MHz LVCMOS oscillators in 2.0x1.6mm packages from compatible manufacturers. Verify pinout compatibility and electrical specifications such as rise/fall times and duty cycle stability before swapping.
