MLS0603-4S7-221

Overview

The Ferroxcube MLS0603-4S7-221 is a multilayer ferrite suppressor in a 0603 (1608 metric) surface-mount package. It provides an impedance of 220 ohms at 100 MHz with a maximum DC resistance of 300 milliohms and a rated current of 200 mA. The component utilizes 4S7 material technology for high-frequency noise attenuation.

Feature Summary

• Multilayer construction for compact EMI suppression
• High impedance performance at 100 MHz
• Low DC resistance to minimize signal loss

Applications

• General electromagnetic interference suppression
• Signal line filtering in portable devices

Procurement Notes

Verify the specific suffix or packaging configuration required, as datasheets may list bulk quantities or reel options. Confirm that the 200 mA current rating and 300 mOhm resistance meet the target circuit's power handling requirements before finalizing the order.

Selection Notes

Select this component when space constraints require a 0603 footprint. Ensure the application operates within the 200 mA limit to prevent saturation. The 220 Ohm impedance value should match the frequency spectrum of the noise being suppressed.

Part Context

This part belongs to the MLS series of multilayer ferrite beads manufactured by Ferroxcube. These components are designed to replace traditional wire-wound beads in applications requiring smaller form factors while maintaining effective high-frequency noise absorption capabilities.

Replacement Considerations

Check for direct substitutes such as the MLS0603-4S7-121 if lower impedance is acceptable. Verify physical compatibility with other 0603 ferrite chips from different manufacturers if supply chain adjustments are necessary.
