782853701

Overview

The Würth Elektronik 782853701 is a Surface Mount Technology (SMT) EMI suppression ferrite bead belonging to the WE-CBA series. It features an 0805 (2012 Metric) package and utilizes a wirewound core construction. The component provides an impedance of 700 Ohms at 100 MHz with a DC nominal current rating of 1.5 Amperes. It operates within a temperature range of -55°C to +125°C and complies with AEC-Q200 standards for automotive applications.

Feature Summary

• Provides effective electromagnetic interference suppression in compact surface mount form factors
• Complies with AEC-Q200 qualification standards for automotive reliability requirements
• Features wirewound core construction for stable performance across wide temperature ranges

Applications

• Automotive electronic circuits requiring EMI filtering
• General purpose power line noise suppression
• Signal integrity protection in high-frequency digital interfaces

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributors before procurement. Confirm that the AEC-Q200 qualification aligns with your specific automotive application requirements. Ensure the 0805 package dimensions fit your PCB layout constraints. Check for any recent product change notifications regarding material composition or manufacturing location changes.

Selection Notes

Select this component when high impedance at 100 MHz is required for EMI suppression in space-constrained designs. The 1.5A current rating suits moderate power line applications. Consider the -55°C to +125°C operating range for harsh environments. Compare against other WE-CBA variants if different impedance values or current ratings are needed for specific circuit topologies.
