MH2029-700T

Overview

The MH2029-700T is a high-current chip ferrite bead from the Bourns MH2029-T series, designed for surface-mount applications. It features a compact 0805 (2012 metric) package with dimensions of 2 mm length, 1.25 mm width, and 0.85 mm height. The component provides an impedance of 70 Ohms at a test frequency of 100 MHz with a tolerance of ±25%. It supports a maximum DC current of 6 A and has a maximum DC resistance of 9 mOhms. The operating temperature range spans from -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 in electronic circuits

Applications

• EMI suppression in power supply lines
• Noise filtering in RF circuits
• Electromagnetic interference protection in consumer electronics such as smartphones and tablets

Procurement Notes

Verify the specific suffix 'T' corresponds to the tape-and-reel packaging configuration required for your assembly process. Confirm that the 70 Ohm impedance value aligns with your target noise frequency spectrum. Ensure the 6 A current rating meets the peak load requirements of your circuit design without exceeding thermal limits.

Selection Notes

Select this component when space constraints require a 0805 footprint but high current capacity is necessary. The low DC resistance minimizes voltage drop in power delivery paths. Consider the wide operating temperature range for environments subject to significant thermal variations. Compare impedance characteristics against other frequencies if the noise spectrum extends beyond 100 MHz.

Part Context

This part belongs to the MH2029-T series of high-current chip ferrite beads manufactured by Bourns. The series is characterized by its ability to handle substantial DC currents while maintaining a small physical size. These components are engineered to address electromagnetic interference challenges in modern portable and high-density electronic devices.

Replacement Considerations

Check for alternative part numbers within the MH2029-T series that offer different impedance values if the 70 Ohm specification does not match your filter requirements. Verify compatibility with existing footprints and soldering profiles before substituting.
