MU2029-471Y

Overview

The MU2029-471Y is a high impedance ferrite chip bead manufactured by Bourns Inc. in the 0805 (2012 metric) surface mount package. It provides an impedance of 470 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 700 mA and features a maximum DC resistance of 350 mOhms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Designed for high impedance applications to suppress electromagnetic interference in power and signal lines.

Applications

• EMI suppression in power lines
• Signal line filtering

Procurement Notes

Verify the specific datasheet version and RoHS compliance status directly with the manufacturer or authorized distributor before procurement. Confirm that the 0805 package dimensions and terminal configuration match the target PCB footprint requirements. Ensure the selected supplier provides valid traceability documentation for quality assurance purposes.

Selection Notes

Select this component when a 470 Ohm impedance at 100 MHz is required for EMI suppression in compact designs. The 0805 package offers a balance between current handling capability and board space efficiency. Consider the 350 mOhm DC resistance impact on voltage drop when designing for low-voltage power rails.

Part Context

This part belongs to the MU series of ferrite beads from Bourns, which are characterized by high impedance values suitable for noise suppression. The MU series utilizes standard SMD packaging to facilitate automated assembly processes in modern electronics manufacturing environments.

Replacement Considerations

MH2029-471Y and MU2029-471Y are listed as direct substitutes for the discontinued Taiyo Yuden BK2125HM471-T.
