LFXTAL003240BULK

Overview

The LFXTAL003240BULK is a quartz crystal resonator manufactured by IQD Frequency Products, designed for high-frequency applications requiring exceptional stability. It operates at a standard frequency of 16 MHz with a load capacitance of 30 pF. The component features a frequency tolerance of ±30 ppm and a frequency stability of ±50 ppm. It utilizes an HC-49/4H package with radial termination style, measuring 11.05 mm in length, 4.7 mm in width, and 4.1 mm in height. The unit supports a drive level of 500 uW and has a series resistance of 40 Ohms. It functions within a temperature range of -20°C to +70°C.

Feature Summary

• Hermetically sealed construction using resistance welding and glass-to-metal seals on leads within an inert atmosphere.
• Industry-standard leaded package design ensuring reliable performance for through-hole mounting.
• High frequency stability and reliability suitable for demanding high-frequency electronic applications.

Applications

• General-purpose timing circuits requiring stable 16 MHz reference
• Microcontroller clock generation systems
• Communication equipment signal processing

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and temperature ranges, as variations may exist between bulk packaging specifications. Ensure compatibility with existing circuit load capacitance requirements before integration. Cross-reference part numbers carefully to avoid confusion with similar family members that may have different stability ratings or operating temperature limits.

Selection Notes

Select this component when a 16 MHz fundamental mode crystal with ±30 ppm tolerance is required for through-hole assembly. The HC-49/4H package offers a robust mechanical solution for environments where surface mount options are unsuitable. Consider the 40 Ohm series resistance and 500 uW drive level to ensure proper oscillator circuit design and longevity. Verify that the ±50 ppm stability meets the system's timing accuracy constraints over the specified -20°C to +70°C operating range.
