Overview
The Würth Elektronik part number 78279220601 is a surface-mount ferrite bead from the WE-MPSA series. It features an 0805 [2012 Metric] package and utilizes multilayer technology. The component provides an impedance of 600 ohms at its rated frequency with a maximum DC current handling of 2.1 A. It has a maximum DC resistance of 0.08 ohms and meets the AEC-Q200 automotive qualification standard.
Feature Summary
- Automotive-grade reliability certified to AEC-Q200 standards
- Multilayer chip construction for compact surface-mount integration
- High current capability suitable for power line filtering applications
Applications
- Automotive electronic circuit protection
- EMI suppression on high-current data lines
- Power supply output filtering
Procurement Notes
Verify the specific suffix and tolerance requirements against the official datasheet before ordering. Confirm that the 0805 footprint matches the target PCB layout. Ensure the 2.1 A current rating aligns with the operational load conditions of the application circuit to prevent saturation or excessive heating during normal operation.
Selection Notes
Select this component when automotive qualification is mandatory for the design. The low DC resistance minimizes voltage drop in power paths. The 600-ohm impedance offers effective noise attenuation for specific frequency ranges. Consider the 0805 size constraint relative to available board space and thermal dissipation requirements for high-current environments.
Part Context
This component belongs to the WE-MPSA series, which focuses on high-current ferrite beads for automotive and industrial use. The series is characterized by robust multilayer structures designed to withstand mechanical stress and thermal cycling typical in automotive under-hood and electronics compartments.
Replacement Considerations
Check for direct cross-references within the WE-MPSA family that share identical impedance and current ratings. Verify pin compatibility and impedance curves for any alternative suppliers to ensure equivalent EMI performance.
