782422241

Overview

The Würth Elektronik 782422241 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features a 0402 (1005 Metric) package with an impedance of 240 ohms at 100 MHz and a maximum DC current rating of 300 mA. The component has a maximum DC resistance of 350 milliohms and operates within a temperature range of -55°C to +125°C. It is AEC-Q200 qualified for automotive applications.

Feature Summary

Provides effective electromagnetic interference suppression in compact surface-mount form factors
Qualified for automotive electronic systems under AEC-Q200 standards
Designed for high-frequency noise attenuation on signal lines

Applications

Automotive electronics requiring AEC-Q200 compliance
High-speed signal line filtering
General EMI suppression in compact devices

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official datasheet before integration. Confirm that the 0402 footprint matches the PCB layout requirements. Ensure the 300 mA current rating meets the operational load conditions of the target circuit to prevent performance degradation.

Selection Notes

Select this component when space constraints require a 0402 package size. Choose this part if the application demands AEC-Q200 qualification for automotive reliability. Consider the 240 ohm impedance at 100 MHz to ensure it aligns with the frequency spectrum of the noise being suppressed in the design.

Part Context

This ferrite bead belongs to the WE-CBA series, which focuses on SMT EMI suppression solutions. The series offers various impedance options in standard metric packages, allowing designers to balance noise reduction capabilities with physical board space limitations in modern electronic assemblies.

Replacement Considerations

Check for other WE-CBA variants with similar 0402 footprints and comparable impedance curves. Verify that any substitute maintains the same AEC-Q200 qualification status and thermal operating range for direct interchangeability in automotive contexts.
