LFXTAL085857

Overview

LFXTAL085857 is a parallel fundamental quartz crystal from the IQXC-42 series, manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with a load capacitance of 10 pF and a maximum equivalent series resistance of 60 Ohms. The component supports a frequency tolerance of ±10 ppm and offers a frequency stability of ±20 ppm over an extended industrial temperature range of -40°C to +125°C. It utilizes a 4-SMD, no lead surface-mount package.

Feature Summary

• Extended temperature operation capability for harsh environments
• High-frequency stability within the specified range
• Compact surface-mount form factor

Applications

• Industrial control systems
• Automotive electronics
• Communication equipment

Procurement Notes

Verify the specific operating temperature range and frequency tolerance requirements against the official datasheet before procurement. Confirm that the 4-SMD no-lead package dimensions align with the target PCB layout. Ensure the load capacitance matches the circuit design specifications to maintain accurate timing performance.

Selection Notes

Select this component when extended temperature resilience up to 125°C is required alongside high stability. Compare it against standard industrial grade crystals if the application environment remains within typical limits. Evaluate the SMD footprint constraints against available board space to ensure proper assembly compatibility.

Part Context

The LFXTAL085857 belongs to the IQXC-42 series, which is designed for demanding applications requiring robust performance. This series provides reliable frequency control solutions suitable for sectors such as automotive and industrial markets where environmental extremes are common.

Replacement Considerations

Check for direct substitutes within the IQXC-42 series or other IQD frequency products that match the 40 MHz frequency, 10 pF load capacitance, and 4-SMD package. Verify equivalent electrical parameters and temperature ratings before substitution.
