7427928161

Overview

The Würth Elektronik part number 7427928161 is a surface-mount EMI suppression ferrite bead belonging to the WE-CBF series. It features a 2220 (5.1 mm) package size and is designed for signal line filtering applications. The component exhibits an impedance of 160 ohms at 100 MHz and supports a current rating of 5000 mA with a maximum DC resistance of 0.01 ohms. It operates within a temperature range of -55°C to +125°C and complies with AEC-Q200 standards.

Feature Summary

• Provides effective electromagnetic interference suppression for high-current signal lines
• Complies with automotive reliability standards including AEC-Q200 certification
• Utilizes a compact surface-mount package suitable for automated assembly processes

Applications

• Automotive electronic systems requiring robust EMI filtering
• High-current signal line protection in consumer electronics
• Industrial equipment noise suppression circuits

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official datasheet prior to integration. Confirm that the selected package dimensions align with the designated PCB footprint constraints. Ensure the operating temperature range meets the environmental requirements of the final assembly. Cross-reference the AEC-Q200 compliance status if the application mandates automotive-grade qualification standards.

Selection Notes

Select this component when high current handling capability is required alongside significant noise attenuation. The low DC resistance minimizes power loss in power-sensitive circuits. Consider the 2220 package size for adequate thermal dissipation and mechanical stability. Evaluate the 160 ohm impedance profile against the target frequency spectrum to ensure effective harmonic suppression without affecting signal integrity.

Part Context

This ferrite bead belongs to the WE-CBF series, which focuses on surface-mount solutions for modern electronics manufacturing. The series emphasizes high current ratings and reliable performance in space-constrained designs. It serves as a critical passive component for maintaining signal purity in dense circuit boards where traditional through-hole options are impractical.

Replacement Considerations
