18QHTF21-10.041-PD

Overview

The 18QHTF21-10.041-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.041 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby mode functionality to reduce power consumption
• Utilizes a leadless surface-mount package design

Applications

• General purpose timing clock generation
• Digital signal processing circuits
• Communication equipment interfaces

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements 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 footprint matches the PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Selection Notes

Select this component when a low-profile, leadless oscillator is required for space-constrained designs. The 1.8V supply voltage makes it suitable for modern low-power digital systems. Consider the LVCMOS output compatibility with standard logic families. Verify that the 10.041 MHz frequency meets the precise timing requirements of the application without needing external dividers.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a supplier specializing in quartz crystals and oscillators. The series typically features small form factors and various frequency options. The 'PD' suffix indicates the inclusion of a power-down feature, distinguishing it from standard continuous-operation variants within the same family.

Replacement Considerations

Direct substitutes must match the 10.041 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm 4-SMD no-lead package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter against the original specification.
