74279265

Overview

The Würth Elektronik 74279265 is a surface-mount EMI suppression ferrite bead from the WE-CBF series, housed in a compact 0603 (1608 metric) package. It provides an impedance of 600 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 200 mA. The component operates within a temperature range of -55°C to +125°C and features a maximum height of 1.00 mm.

Feature Summary

• Provides effective electromagnetic interference suppression for high-frequency noise
• Designed for space-constrained surface-mount applications
• Complies with AEC-Q200 automotive qualification standards

Applications

• Automotive electronics systems
• Portable digital devices
• High-speed data line filtering

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to integration. Confirm that the selected package dimensions align with the designated PCB footprint requirements. Ensure compliance with RoHS directives and relevant environmental regulations for the intended deployment region.

Selection Notes

Select this component when circuit design requires significant attenuation of high-frequency noise within a limited board area. The 200 mA current rating suits low-power signal lines rather than high-current power rails. Evaluate the thermal performance characteristics to ensure stable operation across the specified wide temperature range during continuous use.

Part Context

This ferrite bead belongs to the WE-CBF series, which focuses on providing reliable EMI suppression solutions in miniature form factors. The series is engineered to meet the rigorous demands of modern electronic assemblies, offering consistent performance across various industrial and consumer applications while maintaining a small physical profile.

Replacement Considerations

Consult the official Wurth Elektronik documentation for verified alternative part numbers within the same series or compatible product lines before substituting components.
