MLP0603-400

Overview

The Ferroxcube MLP0603-400 is a multilayer EMI suppression ferrite bead in a 0402 (1005 metric) surface-mount package. It provides an impedance of 40 Ohms at 100 MHz with a rated current capacity of 3 Amperes and a maximum DC resistance of 35 milliohms.

Feature Summary

• Multilayer construction for compact EMI suppression
• High current handling capability
• Low DC resistance to minimize signal loss

Applications

• Motherboard noise filtering
• Notebook computer peripheral protection
• CD-ROM and DVD-ROM drive circuits
• Scanner interface lines

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against the official datasheet before ordering. Confirm that the 0402 footprint matches the PCB layout. Ensure the supplier provides genuine Ferroxcube components with traceable documentation to guarantee performance consistency in high-speed digital applications.

Selection Notes

Select this component when space constraints require a 0402 footprint but high current carrying capacity is necessary. The 40 Ohm impedance at 100 MHz targets common noise frequencies in digital logic interfaces. Compare the DC resistance impact on power integrity against alternative values if voltage drop is critical.

Part Context

This part belongs to the Ferroxcube MLP series of multilayer suppressors designed for integrated EMI filtering. Unlike discrete beads, these chips integrate multiple ferrite layers within a single ceramic body, offering consistent performance in dense circuit board layouts where traditional wound components cannot fit.

Replacement Considerations

Check for direct substitutes from other manufacturers offering identical 0402 dimensions, 40 Ohm @ 100 MHz impedance, and 3A current ratings. Verify that any replacement maintains the same low DC resistance profile to ensure equivalent signal integrity in the target application.
