782853112

Overview

The Würth Elektronik 782853112 is a surface-mount EMI suppression ferrite bead from the WE-CBA series, housed in an 0805 (2012 Metric) package. It provides an impedance of 1100 Ohms at 100 MHz with a maximum DC resistance of 300 milliohms and a rated current of 800 mA. Designed for signal line filtering, it operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.

Feature Summary

• Provides high-impedance EMI suppression for single signal lines
• Qualified for automotive applications under AEC-Q200 standards
• Supports operation across extended industrial temperature ranges

Applications

• Automotive electronic signal line filtering
• High-frequency noise suppression in compact PCB layouts
• EMI mitigation in consumer electronics data interfaces

Procurement Notes

Verify the specific suffix code against the manufacturer's official datasheet to confirm exact electrical tolerances and packaging configuration. Ensure the component matches the required impedance curve and current rating for the target circuit design before finalizing procurement orders.

Selection Notes

Select this component when high attenuation is required for single-ended signals in space-constrained designs. The 0805 footprint offers a balance between current handling capability and board area efficiency compared to smaller packages.

Part Context

This part belongs to the WE-CBA series of SMD ferrite beads manufactured by Würth Elektronik. The series is engineered for effective electromagnetic interference suppression in modern electronic devices requiring reliable performance in compact form factors.

Replacement Considerations

Consult official cross-reference lists for verified substitutes. Ensure any replacement matches the 1100 Ohm impedance at 100 MHz, 800 mA current rating, and 0805 package dimensions.
