Overview
The Ferroxcube MLS0805-4S7-102 is a surface-mount multilayer ferrite bead designed for electromagnetic interference suppression. It features an 0805 (2012 Metric) case style with a monolithic structure ensuring a closed magnetic path and high reliability. The component exhibits an impedance of 1 kΩ at 100 MHz and operates within a temperature range of -40°C to +125°C. Electrical specifications include a maximum DC resistance of 0.5 Ω and a current rating of 200 mA.
Feature Summary
- Monolithic construction providing a closed magnetic path for enhanced reliability
- High impedance performance effective for broadband noise attenuation
- Compact surface-mount form factor suitable for automated assembly
Applications
- Computer and peripheral equipment motherboards
- Notebook and portable device circuitry
- Optical drive systems including CD-ROM and DVD-ROM units
Procurement Notes
Verify the specific material designation 4S7 matches the required frequency response characteristics for your design. Confirm that the 200 mA current rating accommodates peak operational loads without saturation. Ensure the 0.5 Ω DC resistance aligns with power loss constraints in the target circuit path.
Selection Notes
Select this component when space-constrained designs require effective EMI filtering in digital signal lines. The 0805 package offers a balance between thermal dissipation and footprint efficiency. Consider the 1 kΩ impedance profile for suppressing high-frequency noise common in computer peripherals and data transmission interfaces.
Part Context
This part belongs to the MLS series of multilayer suppressors from Ferroxcube. These components utilize specialized ferrite materials optimized for high-frequency attenuation. The series is engineered for integration into dense printed circuit boards where traditional wire-wound inductors are impractical due to size or self-resonance limitations.
Replacement Considerations
Cross-reference with other 0805 ferrite beads offering similar 1 kΩ impedance at 100 MHz. Verify compatibility regarding physical dimensions, terminal metallization, and thermal handling capabilities before substitution.
