LFXTAL024944BULK

Overview

The LFXTAL024944BULK is a fundamental mode quartz crystal resonator manufactured by IQD Frequency Products. It operates at a nominal frequency of 16 MHz with a frequency tolerance and stability of ±30 ppm. The component utilizes the HC49/4H package style, featuring radial leads for through-hole mounting. Electrical specifications include a maximum equivalent series resistance (ESR) of 40 ohms and a drive level of 500 µW. It is designed to function within an operating temperature range of -20°C to +70°C.

Feature Summary

• Fundamental vibration mode operation ensures precise frequency control
• HC49/4H package provides robust mechanical structure for through-hole applications
• Low equivalent series resistance supports efficient circuit integration

Applications

• General-purpose timing circuits requiring 16 MHz reference
• Microcontroller clock sources in industrial environments
• Communication equipment baseband processing stages

Procurement Notes

Verify the specific suffix 'BULK' indicates bulk packaging rather than tape-and-reel when ordering. Confirm that the HC49/4H form factor aligns with the target PCB footprint and hole spacing requirements. Ensure the ±30 ppm stability meets the system's jitter and synchronization constraints before finalizing procurement.

Selection Notes

Select this component when a standard through-hole crystal is required for 16 MHz applications. The HC49/4H package offers higher power handling compared to surface-mount alternatives. Consider the ±30 ppm tolerance against the host oscillator circuit's accuracy needs. Verify that the 500 µW drive level is compatible with the driving gate circuitry to prevent overdriving.

Part Context

This part belongs to IQD's extensive portfolio of quartz crystal resonators, which includes various package sizes from miniature SMD to traditional through-hole formats. The HC49/4H series is widely recognized in the electronics industry for its reliability and cost-effectiveness in general timing applications.

Replacement Considerations

Direct substitutes must match the 16 MHz frequency, HC49/4H package dimensions, and ±30 ppm tolerance. Verify ESR limits and drive level compatibility with existing circuit designs to ensure seamless replacement without performance degradation.
