782429601

Overview

The Würth Elektronik 782429601 is a surface-mount ferrite bead from the WE-CBA series, designed for high-frequency noise suppression in compact electronic circuits. It features a 0402 [1005 Metric] package with two pins and supports a current rating of 0.85 A. The component exhibits an impedance of 600 Ω at 100 MHz and a maximum DC resistance of 0.25 Ω. These electrical characteristics define its performance in filtering applications within space-constrained environments.

Feature Summary

• Provides effective attenuation of high-frequency electromagnetic interference signals
• Utilizes a compact surface-mount footprint suitable for dense PCB layouts
• Maintains signal integrity while suppressing common-mode noise

Applications

• High-speed data line filtering
• Power supply output decoupling
• RF circuit noise suppression

Procurement Notes

Verify the specific suffix codes against official datasheets to confirm exact impedance tolerances and packaging configurations. Ensure compatibility with standard reflow soldering profiles. Confirm RoHS compliance status through manufacturer documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when space constraints require a 0402 package size. Evaluate the 0.85 A current rating against peak load requirements to prevent saturation. Consider the 600 Ω impedance profile for target frequency ranges above 100 MHz to ensure adequate noise attenuation without excessive signal loss.

Part Context

This ferrite bead belongs to the WE-CBA series, which focuses on miniaturized components for modern electronics. The series addresses the industry demand for smaller passive components that maintain high performance in portable devices and advanced computing hardware where board real estate is limited.

Replacement Considerations

Cross-reference with other WE-CBA series variants or equivalent 0402 ferrite beads from other manufacturers. Verify matching impedance curves and current ratings to ensure functional equivalence in existing designs.
