MH2029-471T

Overview

The MH2029-471T is a high-current ferrite bead from Bourns, housed in a compact 0805 (2012 metric) SMD 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 2.5 A and features a maximum DC resistance of 50 mOhms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Compact thin profile suitable for dense PCB layouts
• High current handling capability for power lines
• Effective suppression of high-frequency noise

Applications

• EMI suppression in power circuits
• Signal line filtering in mobile devices
• Noise reduction in consumer electronics

Procurement Notes

Verify the specific suffix 'T' against the manufacturer's datasheet to confirm packaging details such as reel size or tape width. Ensure the impedance value of 470 Ohms matches the target noise frequency requirements. Confirm RoHS compliance status if required by the final assembly specifications.

Selection Notes

Select this component when space constraints require an 0805 footprint but higher current capacity than standard beads offers. The 2.5 A rating suits moderate power applications. Verify that the 50 mOhm DCR meets voltage drop limitations in the circuit design.

Part Context

This part belongs to the MH2029-T series of high-current ferrite beads designed for EMI suppression. The series utilizes iron oxide materials to provide stable impedance characteristics across a wide temperature range, addressing noise issues in modern electronic devices.

Replacement Considerations

Check for direct substitutes within the MH2029 series with different impedance values if noise profiles vary. Cross-reference other manufacturers offering 0805 ferrite beads with similar 2.5 A ratings and 470 Ohm impedance at 100 MHz.
