742792094

Overview

The Würth Elektronik part number 742792094 is a ferrite chip bead from the WE-CBF series, designed for surface mount applications in the 0805 (2012 metric) package. It provides an impedance of 2200 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 200 mA and features a maximum DC resistance of 500 mOhms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high impedance attenuation for EMI suppression in signal lines
• Automotive qualified under AEC-Q200 standards
• Compact surface mount design suitable for space-constrained PCB layouts

Applications

• EMI suppression in automotive electronic systems
• Signal line filtering in consumer electronics
• Noise reduction in portable device power circuits

Procurement Notes

Verify the specific impedance value of 2200 Ohms against circuit requirements. Confirm the 0805 package dimensions match the footprint. Ensure the 200 mA current rating meets the application's load conditions. Check for RoHS compliance status as indicated in official documentation.

Selection Notes

Select this component when high attenuation is required at 100 MHz for small form factor designs. Consider the 200 mA current limit for low-power signal lines. The AEC-Q200 qualification makes it suitable for automotive environments requiring reliability.
