74279226101

Overview

The Würth Elektronik 74279226101 is a WE-MPSB series multi-layer power suppression ferrite bead designed for surface-mount applications. It features an 1812 package with dimensions of 4.5mm length, 3.2mm width, and 1.0mm height. The component provides an impedance of 100Ω at 100MHz and supports a rated current of 8A. Its maximum DC resistance is 0.006Ω, ensuring minimal signal loss in high-current circuits. Certified to AEC-Q200 standards, it operates within a temperature range of -55°C to +125°C.

Feature Summary

Multi-layer construction for effective EMI suppression in compact footprints
High current handling capability suitable for power line filtering
Automotive-grade reliability certified under AEC-Q200 standards

Applications

Power supply input/output filtering in automotive electronics
EMI suppression on data lines in digital communication devices
Noise reduction in industrial control system power stages

Procurement Notes

Verify the specific suffix against official Wurth documentation to confirm impedance tolerance and packaging configuration. Ensure the selected variant matches the required current rating and package dimensions for your PCB layout. Cross-reference the datasheet revision date to guarantee compatibility with your design specifications.

Selection Notes

Select this component when high current capacity and low DC resistance are critical alongside EMI suppression. The 1812 package offers a balance between thermal performance and board space efficiency. Consider the 100Ω impedance profile for target noise frequencies around 100MHz in power distribution networks.

Part Context

This part belongs to the WE-MPSB family, which specializes in multi-layer power suppression beads. These components integrate magnetic material layers to provide stable impedance characteristics under varying bias conditions. The series is engineered for robust performance in demanding electronic environments requiring reliable noise attenuation.
