18QHTF21-100.040041-PD

Overview

The 18QHTF21-100.040041-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 100.040041 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) function to reduce power consumption when not in use. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic levels
• Includes Standby mode capability for power management
• Utilizes a leadless surface-mount package design

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the exact frequency tolerance and load capacitance requirements against the specific application datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead footprint matches the PCB layout constraints. Cross-reference the part number suffix PD with manufacturer documentation to confirm packaging specifications.

Selection Notes

Select this component when a precise 100.040041 MHz reference is required in low-voltage environments. The LVCMOS interface ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency during idle periods is a critical design parameter. Evaluate the small form factor against available board space limitations.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series typically offers various frequencies within a standardized 1.8V LVCMOS format. Mercury Electronics has a history of manufacturing crystal components since 1973, positioning this part within their standard XO lineup for general-purpose timing applications.

Replacement Considerations

Direct substitutes include other 100.040041 MHz LVCMOS oscillators in 4-SMD packages from compatible manufacturers. Verify pinout compatibility and electrical parameters such as current consumption and phase noise. Alternative part numbers like 18QHTF21 variants with different frequencies are not interchangeable without circuit modification.
