18QHTF21-100.040-OE

Overview

The 18QHTF21-100.040-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 100.04 MHz and utilizes LVCMOS output logic levels. The device supports a supply voltage of 1.8V and includes an enable/disable control function for power management flexibility. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component is designed for applications requiring precise timing signals in space-constrained electronic circuits.

Feature Summary

• LVCMOS output interface for digital compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

• Digital signal processing systems
• Communication equipment timing references
• Embedded microcontroller clock sources

Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to ensure compliance with RoHS standards and lead-free specifications. Confirm that the 1.8V supply requirement aligns with the target system's power rails. Check for any updated pinout configurations or thermal requirements associated with the 4-SMD package before finalizing procurement orders.

Selection Notes

Select this component when a 100.04 MHz reference frequency is required with low voltage operation. The LVCMOS output is suitable for direct interfacing with standard digital logic families. Consider the small 2.0x1.6 mm footprint for high-density PCB layouts. Ensure the enable/disable feature meets the system's power cycling or standby mode requirements.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd, a supplier specializing in quartz crystals and oscillators. The series typically offers various frequency options within a standardized small outline package format. Mercury Electronics has a long history in the Taiwan frequency-control industry, providing components for consumer and industrial electronics.

Replacement Considerations

Direct substitutes include other 100.04 MHz LVCMOS oscillators in 4-SMD packages with 1.8V operation. Verify pin compatibility and electrical parameters such as load capacitance and drive level. Alternative part numbers from different manufacturers must match the physical footprint and output logic type to ensure seamless integration.
