MH4532-700Y

Overview

The MH4532-700Y is a high current chip ferrite bead from the Bourns MH series, designed for surface mount applications. It features an impedance of 70 Ohms at a test frequency of 100 MHz and supports a maximum DC current of 6 A. The component has a maximum DC resistance of 60 mOhms and operates within a temperature range of -55°C to +125°C. Its physical dimensions are 4.50 mm in length, 3.20 mm in width, and 1.70 mm in height, conforming to the 1812 package style.

Feature Summary

• High resistance to heat and humidity
• Resistance to mechanical shock and pressure
• Accurate dimensional consistency

Applications

• Filtering power lines in high-frequency circuits
• Filtering signal lines in high-frequency applications
• EMI suppression in high current environments

Procurement Notes

Verify the specific impedance value and current rating against the latest official datasheet before integration. Confirm that the 1812 package dimensions align with the target PCB footprint. Ensure the operating temperature range meets the environmental requirements of the final assembly. Check for any recent updates to the RoHS compliance status or material declarations.

Selection Notes

Select this component when high current handling capability is required alongside EMI filtering. The 6 A rating makes it suitable for power supply outputs. The 70 Ohm impedance at 100 MHz targets specific noise frequencies. Consider the low DC resistance to minimize voltage drop and power loss in the circuit path.

Part Context

This part belongs to the MH series of high current chip ferrite beads manufactured by Bourns Inc. The series is characterized by its robust construction and ability to handle significant DC currents while providing effective noise attenuation. The 1812 case size offers a balance between current capacity and board space efficiency.

Replacement Considerations

Consult official substitution guides for compatible parts within the same series or equivalent performance specifications. Verify that alternative components match the 1812 footprint and 6 A current rating. Ensure the replacement maintains the required 70 Ohm impedance at 100 MHz.
