MLS0805-4S7-151

Overview

The Ferroxcube MLS0805-4S7-151 is a surface-mount multilayer ferrite suppressor in an 0805 (2012 metric) package. It provides an impedance of 150 Ohms at 100 MHz with a DC resistance maximum of 0.25 ohms and a current rating of 300 mA. Designed for high-frequency noise attenuation, this component integrates into compact circuit layouts to manage electromagnetic interference without significant signal degradation.

Feature Summary

• Multilayer construction enables effective suppression of high-frequency noise in dense PCB environments
• Surface-mount design facilitates automated assembly and space-constrained applications
• Low DC resistance minimizes power loss and voltage drop in the signal path

Applications

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

Procurement Notes

Verify the specific impedance tolerance and current rating against the latest official datasheet before integration. Confirm that the 0805 footprint matches the target PCB layout. Ensure the operating temperature range aligns with the system requirements. Cross-reference the manufacturer part number to avoid confusion with similar series variants.

Selection Notes

Select this component when a low-profile solution is required for EMI reduction in portable electronics. The 300 mA rating suits low-power signal lines rather than high-current power rails. Consider the 150 Ohm impedance profile for frequencies around 100 MHz. Evaluate thermal constraints as the small package has limited heat dissipation capabilities compared to larger through-hole beads.

Part Context

This part belongs to the MLS Series of multilayer ferrite suppressors from Ferroxcube. These components are engineered for modern electronic devices requiring compact noise filtering solutions. The series supports various impedance values and current ratings to accommodate different circuit needs within consumer and industrial electronics.

Replacement Considerations

Check for direct substitutes such as the MLS0805-4S7-121 or MLS0805-4S7-221 if impedance or current requirements differ. Verify pin compatibility and physical dimensions before swapping parts to ensure mechanical fit.
