Overview
The Ferroxcube MLS1206-4S4-121 is a multilayer ferrite bead designed for surface mount applications in the 1206 [3216 Metric] package. It provides an impedance of 120 ohms at 100 MHz to suppress electromagnetic interference. The component supports a DC current rating of 500 mA with a maximum DC resistance of 0.15 ohms and an impedance tolerance of ± 25%. This series is engineered for effective noise attenuation in compact electronic designs.
Feature Summary
- Multilayer construction for high-density surface mount integration
- Effective electromagnetic interference suppression across frequency bands
- Designed for stable performance under specified DC bias conditions
Applications
- Motherboard noise filtering
- Notebook computer peripheral circuits
- CD-ROM and DVD-ROM drive interfaces
- Scanner signal line protection
Procurement Notes
Verify the specific impedance value and DC current rating against the official datasheet before procurement. Ensure the 1206 package dimensions align with the target PCB footprint. Confirm that the 0.15 ohm DC resistance meets the circuit's power loss requirements. Cross-reference the manufacturer part number to avoid confusion with similar series variants.
Selection Notes
Select this component when a 120 ohm impedance at 100 MHz is required for EMI suppression. The 500 mA current rating suits moderate power signal lines. Consider the 1206 package size for space-constrained layouts. Evaluate the 0.15 ohm resistance impact on voltage drop within the specific application circuit.
Part Context
This part belongs to the Ferroxcube MLS Series, which comprises multilayer ferrite beads intended for suppressing electromagnetic interference in electronic circuits. The series offers various impedance values and current ratings within standardized surface mount packages to support diverse design needs.
Replacement Considerations
Consult official Ferroxcube documentation for direct substitutes. Verify equivalent impedance, current rating, and package dimensions when considering alternative components from other manufacturers.
