Overview
The Würth Elektronik 74279228260 is a WE-MPSB series multilayer suppression bead in a 0603 (1608 metric) surface-mount package. It provides an impedance of 26 ohms at 100 MHz with a maximum DC current rating of 6.5 A and a maximum DC resistance of 8 milliohms. The component operates within a temperature range of -55°C to +125°C, features a 25% impedance tolerance, and complies with AEC-Q200 automotive standards.
Feature Summary
- Multilayer construction for effective electromagnetic interference suppression
- High current handling capability suitable for power line applications
- Automotive qualification ensuring reliability under harsh conditions
Applications
- Power supply filtering in automotive electronics
- Noise suppression on high-current data lines
- EMI mitigation in digital devices requiring compact components
Procurement Notes
Verify the specific suffix codes against official datasheets to confirm exact electrical tolerances and packaging configurations. Ensure compatibility with automated pick-and-place equipment due to the 0603 footprint dimensions. Cross-reference RoHS compliance status directly with manufacturer documentation prior to integration into regulated assemblies.
Selection Notes
Select this component when space constraints require a 0603 footprint alongside high current requirements up to 6.5 A. The 26-ohm impedance at 100 MHz targets specific noise frequencies. Consider the low DC resistance to minimize voltage drop and power loss in sensitive power distribution networks compared to higher-resistance alternatives.
Part Context
This part belongs to the WE-MPSB series, designed specifically for multilayer suppression applications. It represents Würth Elektronik's approach to combining high-performance ferrite materials with robust surface-mount technology for modern electronic designs demanding both size reduction and electrical efficiency.
Replacement Considerations
Consult official substitution guides for equivalent impedance and current ratings. Verify that any alternative maintains AEC-Q200 certification if used in automotive contexts. Ensure physical footprint compatibility before replacing.
