LFXTAL085842

Overview

The LFXTAL085842 is a 16 MHz fundamental mode quartz crystal from the IQXC series, manufactured by IQD Frequency Products. It features a 4-SMD no-lead package measuring 2.0 mm x 1.6 mm with a maximum height of 1.0 mm. The component operates within an extended temperature range of -40°C to +125°C. Key electrical specifications include a frequency tolerance of ±10 ppm and a frequency stability of ±50 ppm. The load capacitance is specified as 8 pF, and the equivalent series resistance (ESR) is typically 50 Ohms.

Feature Summary

• Extended temperature operation suitable for harsh environments
• Compact surface-mount footprint for space-constrained designs
• Fundamental mode resonance for stable frequency generation

Applications

• Automotive electronics systems
• Industrial control equipment
• High-reliability communication modules

Procurement Notes

Verify the specific load capacitance requirement against the target oscillator circuit design, as this component utilizes an 8 pF specification which differs from standard 18 pF common values. Confirm that the operating temperature range meets the environmental conditions of the final application. Ensure the 4-SMD no-lead package dimensions align with the PCB land pattern guidelines provided in the official datasheet to guarantee proper solder joint integrity during assembly.

Selection Notes

Select this model when a small form factor is required alongside high thermal resilience. The 16 MHz frequency is standard for microcontroller clock sources. Consider the ±10 ppm initial tolerance for precision timing needs. The extended temperature rating distinguishes it from commercial-grade alternatives, making it appropriate for automotive or outdoor industrial deployments where ambient temperatures fluctuate significantly beyond standard ranges.

Part Context

This part belongs to the IQXC series of miniature quartz crystals designed for IoT and smart devices. IQD Frequency Products specializes in frequency control solutions, offering various SMD and THT options. The LFXTAL085842 represents the company's capability to provide robust components within the Wurth Group portfolio, catering to markets requiring reliable timing elements under demanding physical constraints.

Replacement Considerations

Direct substitutes must match the 16 MHz frequency, 4-SMD 2.0x1.6mm package, and -40 to +125C temperature range. Verify compatibility regarding load capacitance (8pF) and ESR values. Cross-reference with other IQD series like CFPX if dimensional changes are permissible.
