Overview
The Würth Elektronik 782853152 is a surface-mount ferrite bead from the WE-CBA series, designed for electromagnetic interference (EMI) suppression in signal lines. It features an 0805 [2012 Metric] package and utilizes a single-line configuration. The component exhibits an impedance of 1500 Ohms at 100 MHz and supports a maximum DC current rating of 700 mA. Its DC resistance is specified as 0.35 Ohms. The device is AEC-Q200 qualified, ensuring reliability for automotive applications.
Feature Summary
- Provides effective EMI suppression for high-frequency noise in signal lines
- AEC-Q200 qualified for automotive application reliability
- Compact 0805 surface-mount footprint for space-constrained designs
Applications
- Automotive electronic systems requiring AEC-Q200 compliance
- Signal line filtering in consumer electronics
- General-purpose EMI suppression in compact PCB layouts
Procurement Notes
Verify the specific impedance tolerance and current derating curves against the official datasheet before integration. Confirm that the 0805 package dimensions align with the target PCB land pattern. Ensure the 700 mA rating meets the operational requirements of the protected circuit under all thermal conditions.
Selection Notes
Select this component when high impedance at 100 MHz is required for signal integrity protection. The low DC resistance minimizes voltage drop in sensitive signal paths. Consider the AEC-Q200 qualification if the design targets automotive standards. Evaluate the 0805 size constraint against available board real estate.
Part Context
This ferrite bead belongs to the WE-CBA series, which focuses on small-footprint solutions for modern electronics. The series offers various impedance values to suit different frequency ranges. The 782853152 variant specifically addresses high-impedance needs in a standard SMD package, balancing performance with manufacturing ease.
Replacement Considerations
Check for direct substitutes within the WE-CBA series with similar 1500 Ohm impedance and 0805 dimensions. Verify that any alternative maintains AEC-Q200 qualification if automotive use is intended. Ensure the replacement matches the 700 mA current rating and 0.35 Ohm DC resistance specifications.
