MLS1206-4S4-501

Overview

The Ferroxcube MLS1206-4S4-501 is a multilayer ferrite bead in a 1206 [3216 Metric] surface-mount package. It provides an impedance of 500 ohms at its rated frequency with a maximum DC resistance of 200 milliohms. The component supports a continuous DC current rating of 400 mA and operates within a temperature range of -40°C to +125°C.

Feature Summary

• Multilayer construction for compact EMI suppression
• High impedance performance in small SMD footprint
• Stable operation across wide industrial temperature ranges

Applications

• Computer and peripheral equipment motherboards
• Notebook computer signal lines
• Portable electronic device power filtering

Procurement Notes

Verify the specific impedance tolerance and DC resistance limits against the official datasheet before integration. Confirm that the 400 mA current rating meets the circuit's peak and steady-state requirements. Ensure the 1206 package dimensions align with the PCB land pattern specifications.

Selection Notes

Select this component when space constraints require a 1206 footprint but higher current handling than standard beads allows. The 500 ohm impedance targets high-frequency noise attenuation. Verify thermal stability requirements against the -40°C to +125°C operating range.

Part Context

This part belongs to the Ferroxcube MLS Series, designed as multilayer suppressors for electromagnetic interference mitigation. The series utilizes soft ferrite materials to provide broadband noise absorption in compact surface-mount formats suitable for modern electronics assembly.

Replacement Considerations

Cross-reference with other MLS1206 variants from Ferroxcube or equivalent manufacturers offering 500 ohms impedance and 400 mA current ratings in 1206 packages. Verify pin compatibility and impedance curves match application needs.
