LFXTAL031646BULK

Overview

The LFXTAL031646BULK is a through-hole quartz crystal manufactured by IQD Frequency Products. It operates at a nominal frequency of 13.0 MHz with a load capacitance of 18 pF. The component utilizes the HC-49/U package and supports fundamental mode operation. Key electrical specifications include a frequency tolerance of ±20 ppm, frequency stability of ±50 ppm, and an equivalent series resistance (ESR) of 70 Ohms. It functions within a temperature range of -10°C to +60°C.

Feature Summary

• Provides stable timing signals for digital circuits using fundamental resonance mode
• Designed for reliable performance in standard industrial operating temperatures
• Compatible with traditional through-hole mounting processes

Applications

• Microcontroller clock generation
• Digital communication interfaces
• General-purpose timing circuits

Procurement Notes

Verify component authenticity against official IQD Frequency Products documentation before integration. Confirm that the specific HC-49/U package dimensions align with the target PCB footprint requirements. Ensure the 18 pF load capacitance matches the oscillator circuit design parameters to maintain specified frequency accuracy. Check current availability status as distribution channels may vary.

Selection Notes

Select this component when a 13.0 MHz fundamental frequency is required for through-hole applications. The HC-49/U package offers robust mechanical stability compared to surface-mount alternatives. Consider the ±20 ppm tolerance for systems requiring precise timing synchronization. Evaluate the 70 Ohm ESR against the oscillator circuit's drive level limitations to prevent over-driving the crystal.

Part Context

This part belongs to the IQD LFXTAL series of general-purpose quartz crystals. It represents a standard solution for basic timing needs where high precision or extreme environmental stability is not critical. The manufacturer provides a wide range of frequencies and packages within this family to support diverse electronic design requirements.

Replacement Considerations

Direct substitutes must match the 13.0 MHz frequency, 18 pF load capacitance, and HC-49/U package. Verify equivalent ESR and tolerance ratings to ensure circuit compatibility.
