Overview
The Würth Elektronik 782853401 is a surface-mount EMI suppression ferrite bead from the WE-CBA series. It features an 0805 [2012 Metric] package with dimensions of 1.2mm width and 0.9mm height. The component provides an impedance of 400 ohms at its rated frequency and supports a DC current rating of 300mA. It operates within a temperature range of -55°C to +125°C and complies with AEC-Q200 standards for automotive applications.
Feature Summary
- Provides effective electromagnetic interference (EMI) suppression through high impedance characteristics.
- Designed for surface-mount technology (SMT) integration into printed circuit boards.
- Qualified for automotive electronics environments under AEC-Q200 reliability 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 specific datasheet version and AEC-Q200 certification status directly with Wurth Elektronik or authorized distributors before procurement. Confirm that the 0805 package dimensions and 300mA current rating align with your design constraints. Ensure compliance with RoHS directives if required by your region. Cross-reference the manufacturer part number 782853401 to avoid substitution errors.
Selection Notes
Select this component when space-constrained PCB layouts require an 0805 footprint for EMI filtering. It is suitable for applications needing 400 ohms impedance with a 300mA continuous current capacity. Consider the -55°C to +125°C operating range for harsh environmental conditions. Verify that the low DC resistance does not introduce excessive voltage drop in the target circuit path.
Part Context
This ferrite bead belongs to the WE-CBA series, which focuses on SMT EMI suppression solutions. The series is engineered for high-performance noise attenuation in compact form factors. Wurth Elektronik positions these components for use in demanding industrial and automotive sectors where reliability and small size are critical.
Replacement Considerations
No public confirmed substitute part numbers are available in the provided documentation. Consult Wurth Elektronik technical support for equivalent alternatives within the WE-CBA series or other compatible ferrite bead families.
