MH2029-111T

Overview

The MH2029-111T is a high-current chip ferrite bead from the Bourns MH2029-T series, housed in a compact 0805 surface-mount package. It provides an impedance of 110 ohms at 100 MHz with a maximum DC resistance of 13 milliohms and a current rating of 5 amperes. Designed for EMI suppression in dense PCB layouts, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Compact 0805 SMD footprint suitable for space-constrained designs
• Low DC resistance minimizes power loss in high-current paths
• High impedance characteristics effectively suppress high-frequency noise
• RoHS compliant and halogen-free construction

Applications

• EMI suppression in power supply circuits
• Noise filtering in RF signal lines
• Consumer electronics such as smartphones and tablets
• Data storage devices including HDD and SSD modules

Procurement Notes

Verify the specific suffix '111' confirms the 110 ohm impedance value, as the MH2029-T series offers a wide range of impedance options. Confirm the tape and reel packaging format matches your automated assembly requirements. Ensure the 5A current rating aligns with your circuit's peak load conditions to prevent saturation or excessive heating during operation.

Selection Notes

Select this component when low DC resistance is critical for maintaining efficiency in high-current applications. The 0805 package size balances current handling capability with board space limitations. Consider the 110 ohm impedance at 100 MHz against the specific noise frequencies present in your design to ensure effective attenuation without impacting desired signal integrity.

Part Context

This part belongs to the MH2029-T series of high-current ferrite beads manufactured by Bourns Electronic Solutions. The series is engineered for demanding environments requiring robust EMI suppression in compact form factors. These components are widely utilized in modern portable electronics and data infrastructure where space constraints and thermal management are primary design considerations.

Replacement Considerations

Consult official Bourns documentation for direct cross-references. Verify that any substitute maintains the 0805 footprint, 110 ohm impedance tolerance, and 5A current rating. Ensure the replacement component meets the same -55°C to +125°C operating temperature range and RoHS compliance standards.
