Overview
The Würth Elektronik part number 78279224101 is a surface-mount ferrite bead from the WE-MPSA series. It features a 2220 (5550 metric) package and utilizes a multilayer ceramic construction. The component provides an impedance of 100 ohms at 100 MHz with a maximum DC resistance of 5 milliohms. It supports a current rating of 7 amperes and operates within a temperature range of -55°C to +125°C. The device holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- Multilayer chip design for high-frequency EMI suppression
- High current handling capability up to 7 amperes
- Automotive grade qualification under AEC-Q200 standards
Applications
- Automotive electronics circuits
- High frequency signal line filtering
- Power supply noise suppression
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the 2220 package dimensions align with your PCB footprint requirements. Ensure the 7A current rating meets the operational demands of your circuit design to prevent saturation or excessive heating during use.
Selection Notes
Select this component when high current capacity is required alongside effective high-frequency noise attenuation. The low DC resistance minimizes power loss in power lines. The AEC-Q200 certification makes it suitable for automotive applications where reliability under varying thermal conditions is critical. Compare impedance characteristics against other frequencies if the noise spectrum differs significantly from 100 MHz.
Part Context
This component belongs to the WE-MPSA series of multilayer ferrite beads manufactured by Würth Elektronik. These components are designed for surface mount technology and offer a compact solution for electromagnetic interference suppression in dense electronic assemblies. The series is characterized by its ability to handle significant DC currents while maintaining effective impedance performance.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with alternative ferrite beads based on package size, impedance curve, and current rating specifications.
