Overview
The Würth Elektronik 782963820 is a single-line signal line ferrite bead from the WE-CBA series, housed in an 1806 (4516 metric) surface-mount package. It provides an impedance of 82 Ohms at 100 MHz with a maximum DC resistance of 20 milliohms and a rated current of 3.5A. The component operates within a temperature range of -55°C to 125°C and meets AEC-Q200 qualification standards.
Feature Summary
- Provides EMI suppression for single signal lines through high-frequency impedance characteristics
- Designed for automotive applications with AEC-Q200 qualification
- Features low DC resistance to minimize power loss in high-current paths
Applications
- Automotive electronic circuit protection
- Signal line filtering in high-speed data interfaces
- EMI suppression in compact consumer electronics
Procurement Notes
Verify the specific ordering suffix to ensure correct packaging format, such as tape and reel or cut tape, as these affect handling but not electrical performance. Confirm that the AEC-Q200 qualification status aligns with your project's automotive reliability requirements before finalizing procurement decisions.
Selection Notes
Select this component when a 1806 footprint is required for signal line filtering with a 3.5A current rating. Ensure the 82 Ohm impedance at 100 MHz matches the target noise frequency spectrum. Verify that the 20 milliohm DC resistance fits within the allowable voltage drop constraints of the circuit design.
Part Context
This part belongs to the WE-CBA series of chip ferrite beads manufactured by Würth Elektronik. The series is characterized by its suitability for automotive environments and compact form factors. The 782963820 specifically addresses the need for reliable EMI suppression in space-constrained PCB layouts requiring robust thermal and electrical performance.
Replacement Considerations
Check for direct substitutes within the WE-CBA series that offer similar impedance curves and current ratings. Ensure any replacement maintains the 1806 package dimensions and AEC-Q200 qualification if automotive compliance is mandatory.
