18QHTF21-6.6128-PD

Overview

The 18QHTF21-6.6128-PD is a crystal oscillator manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a frequency of 6.6128 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a power-down function for standby mode control. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes power-down functionality for energy management
• Utilizes LVCMOS output interface

Applications

• Battery-powered portable devices
• Compact electronic systems requiring low profile components

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required supply voltages and output types. Confirm that the package type matches the PCB footprint requirements. Check datasheet specifications for operating temperature ranges and load capacitance values before integration into final designs.

Selection Notes

Select this component when a small form factor is critical due to its 2.0x1.6 mm size. Consider the 1.8V supply requirement for system power rail compatibility. Evaluate the need for power-down capabilities if battery life extension is a primary design goal.

Part Context

This part belongs to the Mercury Electronic Ind., Co., Ltd. oscillator family, which includes various quartz crystals and timing solutions. The manufacturer has been producing frequency control products since 1973, specializing in Taiwan-based manufacturing for global markets.

Replacement Considerations

Direct substitutes include other models from the same series such as 18QHTF21-18.1059-PD or 18QHTF21-50.4067-PD, provided the frequency difference is acceptable for the application.
