Overview
The Würth Elektronik 7427922808 is a surface-mount EMI suppression ferrite bead from the WE-MPSB series. It features a 0603 (1608 metric) package and utilizes 4W620 material composition. The component provides an impedance of 8 Ohms at 100 MHz with a maximum DC current rating of 9500 mA. It has a maximum DC resistance of 5 mOhms and operates within a temperature range of -55°C to +125°C. The device holds AEC-Q200 qualification for automotive reliability.
Feature Summary
- High current handling capability suitable for power line filtering applications
- AEC-Q200 qualified for automotive electronic system requirements
- Compact 0603 surface mount footprint for space-constrained designs
Applications
- Automotive electronics power supply filtering
- General purpose EMI suppression on high-current data lines
- DC-DC converter output noise reduction
Procurement Notes
Verify the specific impedance tolerance and DC resistance values against the official manufacturer datasheet prior to finalizing design specifications. Confirm that the selected packaging format aligns with automated assembly equipment capabilities. Ensure compliance with REACH and RoHS directives as stated in the product documentation.
Selection Notes
Select this component when high current capacity is required alongside moderate impedance characteristics. The 0603 package size offers a balance between current handling and board space efficiency. Consider the low DC resistance to minimize voltage drop and power loss in high-current paths compared to higher impedance alternatives.
Part Context
This part belongs to the WE-MPSB series, designed specifically for high-current EMI suppression. Unlike standard signal line ferrites, this series prioritizes high saturation current while maintaining effective noise attenuation. It serves as a critical passive component for stabilizing power integrity in noisy electromagnetic environments.
Replacement Considerations
Cross-reference with other Wurth WE-MPSB variants or equivalent high-current SMD ferrite beads from other manufacturers. Verify that substitute parts match the 0603 footprint, 9500 mA current rating, and 8 Ohm impedance at 100 MHz to ensure functional compatibility.
