18QHTF21-10.430-PD

Overview

The 18QHTF21-10.430-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 10.43 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm. This component serves as a precise clock source for digital circuits requiring stable timing signals.

Feature Summary

• Supports standby power-down mode for energy efficiency
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact 4-SMD no-lead surface mount package design

Applications

• General purpose clock generation for digital systems
• Timing reference for microcontrollers and processors
• Low-power embedded electronic devices

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply voltage aligns with your system's power rails. Confirm that the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to ensure reliability under your environmental conditions.

Selection Notes

Select this component when a stable 10.43 MHz clock signal is required with minimal power consumption. The LVCMOS output ensures compatibility with standard digital logic families. The small form factor makes it suitable for space-constrained designs. Consider the standby feature if power management during idle periods is a priority for the application.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options. Mercury Electronic has a long history in quartz crystal manufacturing, providing frequency control products including TCXOs and VCXOs. This specific model represents a standard XO solution within their portfolio.

Replacement Considerations

Compatible substitutes include other 10.43 MHz LVCMOS oscillators in similar packages such as the 18QHTF21-10.430 without the PD suffix if power-down is not needed, or equivalent parts from other manufacturers offering 2.0x1.6mm SMD oscillators with matching electrical specifications.
