18QHTF21-10.410-PD

Overview

The 18QHTF21-10.410-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.41 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and supports a standby or power-down mode for energy management. It is housed in a compact 4-SMD, no lead package suitable for surface-mount assembly. The component is designed for timing applications requiring precise frequency control within the specified operating temperature range.

Feature Summary

• Supports low-power standby mode for efficient energy management
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact 4-SMD no-lead package design for space-constrained layouts

Applications

• General-purpose digital timing circuits
• Microcontroller clock sources
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific frequency tolerance and operating temperature range against the official datasheet before integration. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint matches the PCB design requirements to avoid assembly issues.

Selection Notes

Select this component when a 10.41 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V supply constraint and standby functionality for battery-operated systems. Evaluate the physical dimensions of the 4-SMD package against available board space compared to alternative oscillator packages.

Part Context

This part belongs to the Mercury Electronics XO (Standard) series, which provides basic timing solutions. The product line includes various frequencies and supply voltages, such as 25QHTF21 variants operating at 2.5V. The 18QHTF21 series specifically targets low-voltage applications, distinguishing it from higher voltage counterparts in the manufacturer's portfolio.

Replacement Considerations

Direct substitutes may include other 10.41 MHz LVCMOS oscillators from different manufacturers if pinout and voltage specifications match. Verify equivalent frequency stability and package dimensions when considering cross-brand replacements.
