MH2029-601T

Overview

The MH2029-601T is a high-current chip ferrite bead from the MH2029-T series, manufactured by Bourns Inc. It utilizes a compact 0805 (2012 metric) surface-mount package with dimensions of 2 mm length, 1.2 mm width, and 0.9 mm height. The component provides an impedance of 600 Ohms at a test frequency of 100 MHz, with a tolerance of ±25%. It supports a maximum DC current rating of 2.3 A and features a maximum DC resistance of 60 mOhms. The device operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides high-frequency noise suppression in dense PCB assemblies through significant impedance characteristics.
• Designed for high-current applications with low DC resistance to minimize power loss.
• Constructed in a compact thin SMD form factor suitable for space-constrained designs.

Applications

• EMI suppression in power lines
• Signal line filtering in mobile devices
• Noise reduction in consumer electronics such as smartphones and tablets

Procurement Notes

Verify the specific suffix 'T' against the manufacturer's official documentation to confirm tape-and-reel packaging configuration. Ensure the impedance value of 600 Ohms matches the design requirements at 100 MHz. Confirm RoHS compliance status via the latest datasheet before integration into regulated products.

Selection Notes

Select this component when high current handling up to 2.3 A is required alongside effective high-frequency attenuation. The 0805 footprint offers a balance between current capacity and board space efficiency. Consider the 60 mOhm DCR for thermal management in power-sensitive circuits.

Part Context

This part belongs to the MH2029-T series of high-current chip ferrite beads. The series is engineered to address EMI issues in modern electronic devices where space is limited but current demands are high. It serves as a passive filter component essential for signal integrity in portable electronics.

Replacement Considerations

Consult the official Bourns datasheet for direct pin-compatible alternatives within the MH2029 series or other manufacturers' high-current ferrite beads. Verify that substitute parts meet the same 600 Ohm impedance and 2.3 A current ratings.
