18QHTF21-1.088-PD

Overview

The 18QHTF21-1.088-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 1.088 MHz and utilizes an LVCMOS output interface. The device is designed for a supply voltage of 1.8V and features a standby (power down) function to manage power consumption. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount applications.

Feature Summary

• Supports low voltage operation at 1.8V
• Includes standby mode for power management
• Compact 4-SMD no lead package design

Applications

• Battery-powered portable devices
• Consumer electronics requiring low power timing
• Embedded systems with space constraints

Procurement Notes

Verify the specific suffix against official documentation to confirm functional differences. Ensure compatibility with target voltage levels and load requirements. Confirm package dimensions match PCB footprint specifications before integration.

Selection Notes

Choose this component for applications requiring precise 1.088 MHz timing with minimal power draw. Evaluate thermal performance and stability requirements against datasheet limits. Consider the standby feature if power efficiency is critical for the system design.
