MH2029-300T

Overview

The Bourns MH2029-300T is a high-current ferrite bead in a compact 0805 surface-mount package. It provides an impedance of 30 ohms at 100 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 8.5 A and features a maximum DC resistance (DCR) of 4 mΩ. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• High current handling capability up to 8.5 A for power line applications
• Low DC resistance minimizes voltage drop and power loss
• Compact 0805 footprint suitable for dense PCB layouts
• Wide operating temperature range for robust performance

Applications

• EMI suppression in power supply circuits
• Noise filtering in RF signal lines
• Portable electronic devices requiring space-saving components

Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration. Confirm the impedance value matches the required noise suppression frequency spectrum for the target application. Ensure the 8.5 A current rating exceeds the peak operational current of the circuit to prevent saturation or thermal failure.

Selection Notes

Select this component when high current capacity is critical alongside EMI suppression. The low DCR makes it suitable for sensitive power rails where voltage integrity is paramount. Compare impedance characteristics against other ferrite beads to ensure effective noise attenuation at the specific interference frequencies present in the design.

Part Context

This part belongs to the MH2029-T series, designed for high-current applications. The series utilizes advanced ferrite materials to maintain stability under heavy load conditions while providing effective broadband noise suppression in compact form factors.

Replacement Considerations

Check for direct substitutes within the MH2029 series with different impedance values if noise profiles differ. Verify pin compatibility and thermal characteristics before substituting with generic 0805 ferrite beads.
