MLS1206-4S4-601

Overview

The Ferroxcube MLS1206-4S4-601 is a surface-mount ferrite bead from the MLS series, designed for electromagnetic interference suppression in compact electronic circuits. It features a 1206 (3216 metric) package size and utilizes 4S4 material composition. The component provides an impedance of 600 ohms at 100 MHz with a maximum DC current rating of 400 mA. Its low DC resistance of 0.3 ohms ensures minimal signal attenuation while effectively filtering high-frequency noise.

Feature Summary

• Multilayer chip construction for reliable surface-mount integration
• High impedance performance for effective high-frequency noise suppression
• Compact 1206 footprint suitable for space-constrained designs

Applications

• Power supply line filtering
• Data bus protection
• Clock signal noise reduction

Procurement Notes

Verify the specific suffix codes to ensure the correct impedance value and material grade match the design requirements. Confirm the package dimensions align with the PCB footprint specifications. Check RoHS compliance status if required by environmental regulations. Ensure the DC current rating meets the operational load conditions to prevent saturation or excessive heating during use.

Selection Notes

Select this component when high-frequency noise suppression is critical in a limited board area. The 4S4 material offers a balance of impedance and current handling. Evaluate the DC resistance impact on power efficiency. Consider the self-resonant frequency characteristics relative to the noise spectrum. Ensure the operating temperature range covers the application environment.

Part Context

This part belongs to Ferroxcube's MLS series of multilayer ferrite beads. These components are engineered for EMI suppression in portable and industrial electronics. The series provides various impedance values and package sizes to accommodate different circuit needs while maintaining small form factors.

Replacement Considerations

Check for equivalent parts with matching 600 Ohm impedance at 100 MHz and 1206 package dimensions. Verify that alternative materials offer similar frequency response characteristics. Ensure current ratings and DC resistance values are comparable to maintain circuit performance.
