782422511

Overview

The Würth Elektronik 782422511 is a surface-mount ferrite bead from the WE-CBA series, designed for EMI suppression in single signal lines. It features a 0402 (1005 metric) package with an impedance of 510 ohms at 100 MHz and a maximum DC current rating of 200 mA. The component has a maximum DC resistance of 0.8 ohms and operates within a temperature range of -55°C to +125°C. It holds AEC-Q200 qualification for automotive reliability.

Feature Summary

• AEC-Q200 qualified for automotive applications
• Compact 0402 surface-mount footprint
• High impedance for effective EMI noise suppression

Applications

• Automotive electronic circuits
• Signal line filtering
• General EMI suppression

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and mechanical dimensions. Ensure compatibility with PCB footprints and reflow soldering profiles. Check for RoHS compliance status as required by project specifications.

Selection Notes

Select this component for space-constrained designs requiring high-frequency noise attenuation. The 200 mA current rating suits low-power signal lines. Verify that the 510 ohm impedance meets the target frequency suppression requirements without excessive signal degradation.

Part Context

This part belongs to the WE-CBA series of chip ferrite beads manufactured by Würth Elektronik. These components are engineered for compact electronics where minimal board space is available. The series offers various impedance values and current ratings to suit different filtering needs across consumer and industrial markets.

Replacement Considerations

Check for equivalent parts with matching 0402 dimensions, 510 ohm impedance at 100 MHz, and 200 mA current handling. Ensure any substitute also holds AEC-Q200 qualification if used in automotive contexts.
