74279215

Overview

The Würth Elektronik part number 74279215 is a surface-mount EMI suppression ferrite bead belonging to the WE-CBF series. It features a 1206 (3216 metric) package with dimensions of 3.2 mm in length, 1.6 mm in width, and 1.0 mm in height. The component provides an impedance of 80 Ohms at a test frequency of 100 MHz. It supports a maximum DC current rating of 3000 mA and has a maximum DC resistance of 15 milliohms. The device operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Feature Summary

Provides effective electromagnetic interference suppression for high-speed signal lines and power distribution networks.
Designed for compact surface-mount assembly using standard SMD/SMT manufacturing processes.
Qualified for automotive applications in accordance with AEC-Q200 reliability requirements.

Applications

Automotive electronics systems requiring EMI filtering
High-speed digital signal line protection
Power distribution network noise suppression

Procurement Notes

Verify the specific suffix against official Wurth Elektronik documentation to confirm exact impedance tolerance and current ratings. Ensure the procurement channel sources genuine components to maintain AEC-Q200 compliance. Cross-reference the datasheet for precise thermal derating curves before final integration.

Selection Notes

Select this component when space constraints require a 1206 footprint with moderate current handling capabilities. The 80 Ohm impedance value targets specific noise frequencies around 100 MHz. Evaluate the 3000 mA current rating against peak load conditions to prevent saturation or excessive heating during operation.

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 values and current ratings tailored for modern electronic designs. It complements other passive components in comprehensive EMC filter strategies.

Replacement Considerations

Direct substitutes must match the 1206 package, 80 Ohm impedance at 100 MHz, and 3000 mA current rating. Verify that alternative parts also meet AEC-Q200 standards if used in automotive contexts. Check physical dimensions and terminal configurations for compatibility.
