782631331

Overview

The Würth Elektronik 782631331 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features a 0603 package with an impedance of 330 ohms at 100 MHz and a maximum DC current rating of 400 mA. The component has a maximum DC resistance of 0.25 ohms and operates within a temperature range of -55°C to +125°C. It holds AEC-Q200 qualification for automotive reliability.

Feature Summary

• Provides electromagnetic interference suppression in compact surface-mount form factor
• Qualified for automotive applications under AEC-Q200 standards
• Designed for high-frequency noise attenuation in signal lines

Applications

• Automotive electronics systems
• High-frequency circuit noise filtering
• Signal line EMI suppression

Procurement Notes

Verify the specific datasheet version and manufacturer documentation to confirm electrical parameters and physical dimensions. Ensure compatibility with automated pick-and-place equipment due to the 0603 package size. Check for RoHS compliance status in official product declarations before integration into production workflows.

Selection Notes

Select this component when space-constrained designs require effective high-frequency noise reduction. The 400 mA current rating suits low-power signal lines rather than power delivery paths. Consider the 330 ohm impedance profile for target frequency bands requiring significant attenuation above 100 MHz.

Part Context

This ferrite bead belongs to the WE-CBA series, which focuses on compact EMI solutions. The 0603 footprint allows for dense PCB layouts. As an AEC-Q200 qualified part, it meets rigorous automotive industry standards for stability and performance under varying environmental conditions.

Replacement Considerations

Cross-reference with other WE-CBA series parts like 782631101 or 782631331 variants if impedance or current ratings differ from design requirements. Verify package compatibility and thermal characteristics when substituting.
