Overview
The Würth Elektronik 782422181 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It provides an impedance of 180 ohms at 100 MHz with a maximum DC resistance of 300 milliohms and a current rating of 400 mA. The component operates within a temperature range of -55°C to +125°C and meets AEC-Q200 automotive qualification standards.
Feature Summary
- Provides electromagnetic interference suppression through high-frequency impedance characteristics
- Designed for surface-mount technology integration on printed circuit boards
- Qualified for automotive applications according to AEC-Q200 standards
Applications
- Automotive electronic circuits requiring EMI filtering
- General-purpose signal line noise suppression
- Power supply output filtering in compact designs
Procurement Notes
Verify the manufacturer part number against official Wurth Elektronik documentation to ensure authenticity. Confirm that the specific suffix matches the required impedance and current ratings. Check for RoHS compliance status as stated in the datasheet. Ensure storage conditions align with manufacturer guidelines for surface-mount components.
Selection Notes
Select this component when a 180-ohm impedance at 100 MHz is required for EMI reduction. Consider the 400 mA current rating for load compatibility. The small form factor suits space-constrained layouts. Verify thermal performance within the specified operating temperature range for the target application environment.
Part Context
This ferrite bead belongs to the WE-CBA series, which focuses on compact EMI suppression solutions. The series supports various impedance values tailored for different frequency ranges. Components are designed for automated assembly processes typical in modern electronics manufacturing.
Replacement Considerations
Direct substitutes must match the 180 ohm impedance at 100 MHz, 400 mA current rating, and 0402 package size. Verify equivalent DC resistance and AEC-Q200 qualification if used in automotive contexts. Cross-reference with Wurth's official replacement guides.
