18QHTF21-3.6864-PD

Oscillators Overview

The 18QHTF21-3.6864-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 3.6864 MHz. It utilizes LVCMOS output logic and requires a 1.8V supply voltage. The device features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Operates on a 1.8V supply voltage
• Features LVCMOS output logic
• Includes standby power down capability

Oscillators Applications

• Battery-powered electronic devices
• Portable consumer electronics
• General clock signal generation

Oscillators Procurement Notes

Verify the specific ordering suffix to ensure correct voltage and output configuration. Confirm that the 4-SMD no-lead package matches the target PCB footprint. Check datasheet specifications for operating temperature range and load capacitance requirements before integration into the design.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for clock synchronization. The small 2.0x1.6mm form factor suits space-constrained designs. Ensure the application supports LVCMOS logic levels and can accommodate the specified standby control functionality.

Oscillators Part Context

This part belongs to the QHTF series of surface-mount oscillators from Mercury Electronic. The series offers various frequencies and voltage options. The 18 prefix typically indicates the 1.8V supply variant within the product line.

Oscillators Replacement Considerations

The 3QHTF21-3.6864-PD serves as a direct functional substitute but operates at 3.3V instead of 1.8V. Verify voltage compatibility before substitution.
