7427927241

Overview

The Würth Elektronik 7427927241 is a multilayer surface-mount ferrite bead from the WE-CBF series, designed for single-line signal filtering. It features a 0402 (1005 Metric) package with dimensions of 1.0 x 0.5 x 0.5 mm. The component provides an impedance of 470 ohms at 100 MHz and supports a DC current rating of 550 mA. Its maximum DC resistance is 0.65 ohms, ensuring minimal signal loss in high-frequency applications.

Feature Summary

• Multilayer SMD construction for compact circuit integration
• High impedance characteristics for effective EMI suppression
• AEC-Q200 qualified for automotive reliability standards

Applications

• Single-line signal filtering
• Automotive electronics systems
• EMI suppression in portable devices

Procurement Notes

Verify the specific datasheet version to confirm AEC-Q200 qualification status and exact electrical tolerances. Ensure the 0402 footprint matches the PCB design constraints. Check for any recent product change notices regarding material composition or manufacturing location updates.

Selection Notes

Select this component when space-constrained designs require high-impedance filtering in a 0402 package. The 550 mA current rating suits low-power signal lines rather than high-current power rails. Consider the 0.65 ohm DCR impact on signal integrity for sensitive analog circuits.
