782853200

Overview

The Würth Elektronik 782853200 is a surface-mount ferrite bead from the WE-CBA series, designed for EMI suppression in signal lines. It features a 0805 (2012 metric) package with dimensions of 2.00mm x 1.20mm and a maximum height of 1.10mm. The component provides an impedance of 20 Ohms at 100 MHz and supports a DC current rating of 5A. Its maximum DC resistance is 8 milliohms. It operates within a temperature range of -55°C to +125°C and holds AEC-Q200 qualification.

Feature Summary

• Provides effective electromagnetic interference suppression for high-speed signal lines
• Supports high DC current loads up to 5 Amperes
• Qualified for automotive applications under AEC-Q200 standards
• Utilizes a compact 0805 surface-mount footprint for space-constrained designs

Applications

• High-speed data line filtering in automotive electronics
• EMI suppression on USB and HDMI interfaces
• Signal integrity protection in industrial control systems
• Noise reduction in consumer electronic device power and signal traces

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official datasheet prior to integration. Confirm that the 0805 package dimensions align with the target PCB land pattern. Ensure the selected packaging format meets assembly requirements. Validate that the component's thermal characteristics are suitable for the intended operating environment.

Selection Notes

Select this component when a low-profile ferrite bead is required for signal lines carrying currents up to 5A. The 20 Ohm impedance at 100 MHz makes it suitable for suppressing noise in digital communication protocols. Consider the AEC-Q200 rating if the application demands automotive reliability standards. Evaluate the low DC resistance to minimize voltage drop across the component in sensitive circuits.

Part Context

This part belongs to the WE-CBA series of chip ferrite beads manufactured by Würth Elektronik. The series is engineered for general-purpose EMI suppression in compact electronic assemblies. The 0805 case size offers a balance between current handling capability and board space efficiency. The product line emphasizes reliability through standardized testing and qualification processes.

Replacement Considerations

Consult manufacturer cross-reference lists for verified substitutes. Ensure any alternative maintains the 0805 footprint, 20 Ohm impedance at 100 MHz, and 5A current rating. Verify compatibility with existing PCB layouts and soldering profiles.
