74269242161

Overview

The Würth Elektronik 74269242161 is a surface-mount EMI suppression ferrite bead from the WE-TMSB series. It features an impedance of 0.15 ohms and a maximum DC current rating of 1 ampere. The component utilizes a 0402 (1005 metric) package with SMD/SMT termination. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Designed for high-current applications requiring low impedance values
• Optimized for EMI noise suppression in signal and low power lines
• Compact 0402 footprint suitable for space-constrained designs

Applications

• Audio signal lines
• Clock circuits
• Video applications

Procurement Notes

Verify the specific impedance value against the official datasheet, as conflicting public sources list both 0.15 ohms and higher values. Confirm RoHS compliance status directly with the manufacturer documentation before finalizing procurement specifications.

Selection Notes

Select this component when low impedance at high current is required. Ensure the 0402 package size fits the PCB layout constraints. Verify that the 1A current rating meets the circuit's operational requirements without saturation.

Part Context

This part belongs to the WE-TMSB series of tiny multilayer suppression beads. These components are engineered to provide effective EMI filtering while maintaining a small physical profile. The series is designed for general EMI filtering in various electronic applications.

Replacement Considerations

Check for direct substitutes within the same WE-TMSB series with compatible impedance and current ratings. Verify package dimensions and thermal characteristics if considering alternative manufacturers.
