LFXTAL011301BULK

Overview

The LFXTAL011301BULK is a quartz crystal resonator manufactured by IQD Frequency Products, designed for surface-mount applications. It operates at a standard frequency of 8 MHz with a tolerance of ±30 ppm and frequency stability of ±50 ppm. The component utilizes a HC-49-4H-SMX package, measuring 11.05 mm in length, 4.7 mm in width, and 4 mm in height. It features a load capacitance of 30 pF and radial termination style suitable for through-hole or surface-mount integration depending on specific board design requirements.

Feature Summary

• Surface-mount compatible construction within the HC-49-4H-SMX form factor
• Hermetically sealed metal can packaging for environmental protection
• Standard 8 MHz frequency output for clock generation circuits

Applications

• Real-time clock (RTC) modules
• Microcontroller clock sources
• General-purpose timing circuits

Procurement Notes

Verify the exact suffix designation against the manufacturer's current datasheet to confirm package variant and compliance status. Ensure the ordering code matches the required surface-mount configuration rather than standard leaded versions. Cross-reference the lot date code if long-term supply continuity is critical for the production timeline.

Selection Notes

Select this component when a compact surface-mount solution is required for an 8 MHz reference signal. The HC-49-4H-SMX package offers a smaller footprint compared to traditional through-hole HC-49/U variants while maintaining similar electrical characteristics. Confirm that the PCB land pattern supports the specific terminal arrangement of the SMD version.

Part Context

This part belongs to the IQD LFXTAL series of quartz crystals, which provides a wide range of frequencies and packages. The LFXTAL011301BULK specifically addresses the need for space-constrained designs requiring reliable 8 MHz timing. It represents the transition from legacy through-hole components to modern surface-mount technologies in industrial and consumer electronics.

Replacement Considerations

Direct substitutes include other 8 MHz crystals in the HC-49-4H-SMX package from IQD or compatible manufacturers. Verify that replacement parts match the 30 pF load capacitance and ±30 ppm tolerance specifications to ensure circuit compatibility.
