Overview
The Würth Elektronik 782853680 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features an 0805 [2012 Metric] package with dimensions of 2.0 mm x 1.25 mm and a height of 0.9 mm. The component provides an impedance of 68 ohms at 100 MHz and has a DC resistance of 0.025 ohms. It supports a DC current rating of 3 A and operates within a temperature range of -55°C to +125°C. The part is qualified under AEC-Q200 standards.
Feature Summary
- Designed for effective EMI suppression in high-frequency circuits
- AEC-Q200 qualified for automotive reliability requirements
- Compact 0805 footprint suitable for space-constrained PCB layouts
Applications
- Automotive electronics systems
- Portable electronic devices
- Data communication equipment
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 project's automotive grade requirements. Ensure the 0805 package dimensions match your PCB land pattern specifications to prevent assembly issues.
Selection Notes
Select this component when a low-profile, high-current ferrite bead is required for EMI filtering. The 68-ohm impedance at 100 MHz targets common noise frequencies in digital circuits. The 3 A current rating allows use in power lines or high-speed data interfaces where minimal DC resistance is critical for signal integrity.
Part Context
This ferrite bead belongs to the WE-CBA series, which focuses on compact SMD solutions for electromagnetic interference suppression. The series is engineered for automated pick-and-place assembly, ensuring consistent performance in mass production environments while maintaining strict dimensional tolerances for reliable soldering.
Replacement Considerations
Check for direct substitutes within the WE-CBA series offering similar impedance and current ratings. Verify that any alternative component maintains the same 0805 footprint and AEC-Q200 qualification if automotive application is required.
