MLS0603-4S7-300

Overview

The Ferroxcube MLS0603-4S7-300 is a multilayer suppressor ferrite bead in an 0603 (1608 metric) package. It utilizes 4S7 material and provides a nominal impedance of 30 ohms at 100 MHz. The component has a maximum DC resistance of 0.1 ohm and supports a rated current of 400 mA. Tolerance is specified at ±25%. It is designed for surface mount assembly.

Feature Summary

• Multilayer construction for compact EMI suppression
• Integrated inductor functionality within the suppressor
• Suitable for high-density surface mount applications

Applications

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

Procurement Notes

Verify the specific suffix against the manufacturer's datasheet to confirm impedance tolerance and current ratings. Ensure the ordering code matches the required 0603 footprint and 4S7 material characteristics. Confirm RoHS compliance status with the supplier prior to procurement.

Selection Notes

Select this component when space constraints require an integrated EMI filter and inductor in an 0603 package. The 4S7 material offers a balance of permeability and resistivity suitable for general-purpose noise suppression in digital logic and peripheral interfaces where low DC resistance is critical.

Part Context

This part belongs to the MLS series of multilayer suppressors from Ferroxcube. These components combine ferrite bead and inductor functions into a single surface-mount device, replacing discrete components to save board space and improve high-frequency performance in portable electronics.

Replacement Considerations

Check for equivalent parts in the same 0603 package with matching 30 ohm impedance at 100 MHz. Verify that substitute components support at least 400 mA current handling and have comparable DC resistance values to ensure circuit compatibility.
