742792096

Overview

The Würth Elektronik part number 742792096 is a surface-mount EMI suppression ferrite bead from the WE-CBF series. It features an 0805 (2012 metric) package with dimensions of 2 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 2700 Ohms at a test frequency of 100 MHz. It supports a maximum DC current of 200 mA and has a maximum DC resistance of 600 mOhms. The device operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Provides high impedance attenuation for electromagnetic interference suppression in compact surface-mount configurations
• Engineered for automotive reliability through compliance with AEC-Q200 qualification standards
• Capable of handling specific DC bias currents while maintaining low direct current resistance

Applications

• Automotive electronics systems requiring AEC-Q200 certified components
• High-frequency signal line filtering in consumer electronics
• Power supply output stages for noise reduction
• Data bus protection against electromagnetic interference

Procurement Notes

Verify the exact impedance value and current rating against the official manufacturer datasheet before integration. Confirm that the 0805 footprint matches the target PCB layout constraints. Ensure the application environment remains within the specified -55°C to +125°C operating temperature range to maintain performance integrity.

Selection Notes

Select this component when high attenuation at 100 MHz is required within a small 0805 form factor. Consider the 200 mA current limit for power path applications. The AEC-Q200 certification makes it suitable for automotive designs where standard industrial parts are insufficient.

Part Context

This ferrite bead belongs to the WE-CBF series, which focuses on small-size SMD solutions for EMI suppression. The series offers various impedance and current combinations within standardized footprints like 0805 and 1806, allowing designers to balance space constraints with filtering requirements across different electronic product categories.
