It operates at a fundamental frequency of 25 MHz with a load capacitance of 10 pF and a frequency tolerance of ±10 ppm. The component exhibits an equivalent series resistance (ESR) of 100 Ohms and supports a frequency stability of ±100 ppm. It features a compact 4-SMD, no-lead package measuring 2.00 mm in length, 1.60 mm in width, and 0.50 mm in height. The device is qualified to AEC-Q200 standards, ensuring reliability for automotive environments, and functions within a temperature range of -40°C to +125°C.

Feature Summary

• AEC-Q200 qualified for automotive electronic reliability
• Ultra-small 4-SMD no-lead surface mount package
• Fundamental mode operation at 25 MHz

Applications

• Automotive infotainment systems
• Engine control unit clock references
• On-board diagnostic interfaces

Procurement Notes

Verify the specific suffix requirements against the latest manufacturer datasheet before ordering, as packaging options may vary between tape-and-reel and cut tape formats. Confirm that the intended application environment remains within the specified -40°C to +125°C operating temperature range to ensure long-term frequency stability. Ensure PCB land patterns match the 2.00mm x 1.60mm footprint dimensions precisely to avoid soldering defects during assembly processes.

Selection Notes

Select this component when a small form factor is required alongside strict automotive qualification standards. The 100 Ohm ESR value must be compatible with the oscillator circuit design to guarantee reliable startup. Consider the 10 ppm initial tolerance if higher precision timing is necessary for the system clock source compared to standard commercial grade alternatives.

Part Context

This part belongs to the IQXC-42 AUTO series, which specializes in ultra-small quartz crystals tailored for space-constrained automotive electronics. The series emphasizes robustness under thermal cycling and vibration, making it suitable for harsh vehicle environments where standard commercial components might fail prematurely due to mechanical stress or extreme temperature fluctuations.
