LFXTAL085844

Overview

LFXTAL085844 is a parallel fundamental quartz crystal from the IQXC-42 series by IQD Frequency Products. It operates at a nominal frequency of 24 MHz with a frequency tolerance of ±20 ppm and stability of ±50 ppm. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 120 Ohms. It utilizes a 4-SMD, no-lead package suitable for surface mount applications. The device supports a wide operating temperature range from -40°C to +125°C, ensuring reliability in demanding environments.

Feature Summary

• Hermetically sealed construction using glass-to-metal seals on leads within an inert atmosphere for enhanced durability.
• Wide industrial temperature rating supporting operation from -40°C to +125°C for robust environmental performance.
• Compact 4-SMD no-lead footprint designed for automated surface mount assembly processes.

Applications

• High-frequency clock generation in industrial control systems
• Timing references in automotive electronics requiring extended temperature ranges
• Communication modules needing stable 24 MHz oscillation

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm exact packaging configuration and compliance certifications. Ensure the selected variant matches the required load capacitance and frequency tolerance specifications for the target circuit design. Cross-reference the part number with the latest product release notes to avoid discrepancies in package dimensions or material composition.

Selection Notes

Select this component when a 24 MHz reference with tight tolerance is required for surface mount designs. The 10 pF load capacitance must match the oscillator circuit requirements. Consider the 120 Ohm ESR value for drive level calculations. The wide temperature range makes it suitable for harsh environments where standard commercial grade crystals would fail.

Part Context

The LFXTAL085844 belongs to the IQXC-42 series, which offers industry-standard leaded and surface mount options. This series emphasizes reliability through resistance-welded, hermetically sealed packages. The 4-SMD form factor provides a compact solution for modern PCB layouts while maintaining the electrical performance characteristics associated with fundamental mode quartz resonators.

Replacement Considerations

Direct substitutes include LFXTAL085845, which shares identical electrical parameters but may differ in packaging or suffix codes. Verify compatibility before substitution as physical dimensions and pin configurations must align with the existing footprint. Consult official cross-reference guides for alternative manufacturers offering equivalent 24 MHz SMD crystals.
