18QHTF21-2.400-PD

Oscillators Overview

The 18QHTF21-2.400-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 2.4 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 with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

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

Oscillators Applications

• General electronic timing circuits
• Low-power embedded systems
• Consumer electronics devices

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and output types. Confirm that the 4-SMD no-lead package matches the target PCB footprint. Check manufacturer documentation for operating temperature ranges and load capacitance requirements before integration into final designs.

Oscillators Selection Notes

Select this component when a precise 2.4 MHz reference signal is required for LVCMOS-compatible digital logic. Consider the 1.8V supply constraint and the availability of a power-down feature for battery-operated applications. Ensure the small form factor fits within the spatial constraints of the intended assembly.

Oscillators Part Context

This part belongs to the Mercury Electronics 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options within a standardized 2.0x1.6 mm package. The PD suffix typically indicates the inclusion of a power-down control pin or functionality.

Oscillators Replacement Considerations

Direct substitutes include other 2.4 MHz LVCMOS oscillators in 4-SMD packages from manufacturers such as Epson, NDK, or SiTime, provided they match the 1.8V supply and pinout configuration.
