18QHTF21-10.0413-PD

Overview

The 18QHTF21-10.0413-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 10.0413 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for timing applications requiring precise clock signals in space-constrained electronic systems.

Feature Summary

• Supports low-voltage operation at 1.8V for compatibility with modern digital circuits
• Includes a standby power-down function to reduce current consumption during idle periods
• Utilizes a small-footprint surface-mount package suitable for high-density PCB layouts

Applications

• Battery-powered portable devices requiring low power consumption
• Digital signal processing systems needing stable clock sources
• Communication equipment utilizing LVCMOS interface standards

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB silkscreen and solder mask definitions. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Choose this oscillator when a 10.0413 MHz frequency is specifically required for your application. Consider the 1.8V operating voltage to ensure compatibility with your logic levels. The low profile and small size make it suitable for devices with strict spatial constraints. Evaluate the standby feature benefits if power management is a critical design factor.
