782422601

Overview

The Würth Elektronik 782422601 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features a 0402 (1005 Metric) package with an impedance of 600 Ω at 100 MHz and a rated DC current of 200 mA. The component operates within a temperature range of -55°C to +125°C and has a maximum DC resistance of 0.8 Ω.

Feature Summary

• Provides high noise suppression performance for signal integrity
• Compact 0402 surface-mount footprint for space-constrained designs
• Designed for effective electromagnetic interference attenuation

Applications

• High-speed data line filtering
• Power supply noise suppression
• General EMI mitigation in compact electronics

Procurement Notes

Verify the specific datasheet version and impedance tolerance when sourcing. Confirm that the 0.8 Ω DC resistance aligns with your circuit's power loss requirements. Ensure the 200 mA current rating meets the operational load without saturation. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component for applications requiring significant attenuation in a minimal footprint. The 600 Ω impedance at 100 MHz targets common high-frequency noise sources. Consider the 0.8 Ω DCR impact on voltage drop if used in low-voltage power rails. The wide operating temperature range supports diverse environmental conditions.

Part Context

This part belongs to the WE-CBA series of SMD EMI suppression ferrite beads. It is designed to replace discrete components or larger ferrite beads in modern PCB layouts. The series focuses on providing reliable noise filtering while maintaining small physical dimensions suitable for dense assembly.

Replacement Considerations

Direct substitutes must match the 0402 package, 600 Ω impedance at 100 MHz, and 200 mA current rating. Verify equivalent DC resistance and temperature coefficients to ensure identical circuit behavior.
