782853301

Overview

The Würth Elektronik 782853301 is a surface-mount ferrite bead from the WE-CBA series, designed for electromagnetic interference (EMI) suppression in compact electronic circuits. It features an 0805 [2012 Metric] package with dimensions of 2mm length. The component exhibits a nominal impedance of 300 Ω at high frequencies and supports a DC current rating of 3A. Its maximum DC resistance is specified as 0.05 ohms with an impedance tolerance of ±25%. Operating within a temperature range of -55°C to +125°C, it meets AEC-Q200 automotive qualification standards.

Feature Summary

• Provides effective EMI noise suppression for high-speed signal lines and power distribution networks.
• Automotive-grade reliability certified under AEC-Q200 standards for harsh environment durability.
• Compact 0805 footprint enables integration into space-constrained printed circuit board layouts.

Applications

• Automotive infotainment and control unit signal line filtering
• High-speed data interface noise suppression
• Power supply output filtering in compact modules

Procurement Notes

Verify the specific suffix and tape/reel packaging configuration against the manufacturer's latest datasheet before ordering. Confirm that the AEC-Q200 certification status aligns with your project's automotive quality requirements. Ensure the 3A current rating and 0.05 ohm DC resistance meet your circuit's thermal and voltage drop constraints during final validation.

Selection Notes

Select this component when a low-profile SMT ferrite bead is required for EMI mitigation in automotive or industrial applications. The 300 Ω impedance offers attenuation for high-frequency noise while maintaining a low DC resistance of 0.05 ohms to minimize signal loss. The 3A current handling capability suits moderate-power signal lines, and the wide operating temperature range ensures stability across extreme environmental conditions.

Part Context

This part belongs to the WE-CBA series of chip ferrite beads manufactured by Würth Elektronik. The series is engineered for surface-mount technology, offering consistent performance for EMI suppression in modern electronics. The 782853301 specifically utilizes a material formulation optimized for high-impedance characteristics in the 0805 package size, balancing electrical performance with mechanical robustness for automated assembly processes.

Replacement Considerations

Cross-reference with other 0805 ferrite beads rated at 300 Ω and 3A if supply constraints exist. Verify that any substitute matches the AEC-Q200 qualification and maintains similar impedance frequency characteristics to ensure equivalent noise suppression performance in the target application.
