782763621

Overview

The Würth Elektronik part number 782763621 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features a 1206 (3216 metric) package and utilizes 4W620 material composition. The component provides an impedance of 620 Ohms at 100 MHz with a maximum DC resistance of 100 milliohms. It supports a current rating of 1.5 Amperes and holds AEC-Q200 automotive qualification.

Feature Summary

• Provides high impedance for effective electromagnetic interference suppression in signal lines
• Automotive qualified to AEC-Q200 standards for reliability in vehicle electronics
• Low DC resistance minimizes power loss and voltage drop in the circuit path

Applications

• Automotive electronic systems requiring AEC-Q200 compliance
• High-speed data line filtering in consumer electronics
• Power supply output filtering for noise reduction

Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to confirm exact tolerance and packaging specifications. Ensure the selected variant matches the required 1206 footprint and 1.5A current rating for your design. Cross-reference the impedance value at 100 MHz to confirm compatibility with your target frequency range. Confirm RoHS compliance status if required by your procurement policy.

Selection Notes

Select this component when designing circuits that require robust EMI filtering with established automotive reliability standards. The low DC resistance makes it suitable for applications where signal integrity and minimal power dissipation are critical. Consider the 1206 package size for board space constraints while ensuring adequate thermal management for the 1.5A current handling capability.

Part Context

This component belongs to the WE-CBA series of surface-mount ferrite beads manufactured by Würth Elektronik. The series is designed for general-purpose EMI suppression in compact electronic devices. The use of proprietary 4W620 material allows for stable performance across varying temperature conditions, supporting its application in both industrial and automotive environments.

Replacement Considerations

Direct substitutes must match the 1206 package, 620 Ohm impedance at 100 MHz, and 1.5A current rating. Verify that any alternative component also meets AEC-Q200 requirements if used in automotive contexts. Check for identical DC resistance values to ensure no impact on circuit power efficiency.
