18QHTF21-10.220-PD

Overview

The 18QHTF21-10.220-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.22 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features a power-down standby mode to reduce consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. The component supports an operating temperature range suitable for general electronic applications.

Feature Summary

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

Applications

• Battery-powered portable devices
