LFXTAL059523

Overview

The LFXTAL059523 is a surface-mount quartz crystal manufactured by IQD Frequency Products. It operates at a fundamental frequency of 12.288 MHz with a frequency tolerance and stability of ±20 ppm. The component features a load capacitance of 18 pF and an equivalent series resistance (ESR) of 70 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 3.20mm x 2.50mm and a maximum height of 0.80mm.

Feature Summary

• Fundamental mode operation for stable timing reference
• Surface-mount design compatible with automated assembly processes
• Standardized 18pF load capacitance for oscillator circuit integration

Applications

• Microcontroller clock generation
• Communication interface timing
• Digital signal processing systems

Procurement Notes

Verify the specific package variant against the official datasheet to ensure compatibility with PCB footprint requirements. Confirm that the ±20 ppm stability meets the system timing budget. Check RoHS compliance status for environmental regulations. Validate the ESR value matches the oscillator driver circuit specifications. Ensure storage conditions adhere to manufacturer guidelines for moisture-sensitive components.

Selection Notes

Select this component when a 12.288 MHz frequency is required for digital logic or communication protocols. The 18pF load capacitance suits standard parallel resonant circuits. Consider the 70 Ohm ESR for driver strength limitations. The SMD form factor is suitable for space-constrained designs requiring reflow soldering compatibility.

Part Context

This part belongs to the IQD Frequency Products quartz crystal portfolio, designed for general-purpose timing applications. It represents a standard commercial-grade solution offering reliable performance in consumer and industrial electronics. The product line emphasizes availability and consistency for mass production environments.

Replacement Considerations

Cross-reference alternative crystals with identical 12.288 MHz frequency, 18pF load capacitance, and 4-SMD package dimensions. Verify that substitute parts meet or exceed the ±20 ppm stability and 70 Ohm ESR specifications. Ensure mechanical footprint compatibility for direct replacement without PCB redesign.
