LFXTAL071261

Overview

The LFXTAL071261 is a surface-mount quartz crystal from the IQXC-42 AUTO series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 27 MHz with a frequency tolerance of ±10 ppm and a frequency stability of ±20 ppm over the industrial temperature range of -40°C to +85°C. The component features a load capacitance of 10 pF and an equivalent series resistance (ESR) of 80 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 2.5 mm in length, 2.0 mm in width, and a maximum height of 0.60 mm.

Feature Summary

• Automotive-grade reliability compliant with AEC-Q200 standards for robust performance in demanding environments
• Compact surface-mount design suitable for space-constrained circuit board layouts
• Industrial temperature range operation ensuring consistent functionality across wide thermal variations

Applications

• Automotive electronic systems requiring certified frequency control components
• Industrial equipment operating within standard industrial temperature ranges
• General-purpose digital circuits utilizing 27 MHz clock signals

Procurement Notes

Verify that the specific order includes the AEC-Q200 qualification status, as this is critical for automotive applications. Confirm the package type matches the 4-SMD no-lead specification to ensure correct footprint compatibility. Check RoHS compliance documentation to meet environmental regulations. Ensure the supplier provides official IQD datasheets for final parameter validation before integration into production designs.

Selection Notes

Select this component when an automotive-certified quartz crystal is required for 27 MHz applications. It is appropriate for designs needing ±10 ppm initial tolerance and ±20 ppm total stability across the -40°C to +85°C range. Choose this part over non-automotive grades if long-term reliability and shock/vibration resistance are priority requirements for the target system environment.

Part Context

This component belongs to the IQXC-42 AUTO series, which is specifically engineered for automotive electronics. IQD Frequency Products, now part of the Wurth Group, leverages decades of experience to provide frequency control solutions. This series represents a specialized subset of their broader quartz crystal portfolio, focusing on high-reliability SMD packages for rigorous industry standards.

Replacement Considerations

Direct substitutes include other IQD parts within the IQXC-42 AUTO series with matching electrical parameters. Cross-manufacturer replacements must match the 27 MHz frequency, 10 pF load capacitance, 4-SMD no-lead package dimensions, and AEC-Q200 certification. Verify that alternative parts meet the same ±10 ppm tolerance and -40°C to +85°C operating range specifications.
