Overview
The Ferroxcube MLS0805-4S7-121 is a multilayer ferrite bead designed for surface-mount applications in the 0805 (2012 Metric) package. It provides an impedance of 120 Ohms at 100 MHz with a tolerance of ±25%. The component supports a DC current rating of 300 mA and features a maximum DC resistance of 0.25 Ohms. This EMI suppression product is engineered to filter high-frequency noise in electronic circuits while maintaining signal integrity.
Feature Summary
- Multilayer construction for effective electromagnetic interference suppression
- Surface-mount design compatible with standard PCB assembly processes
- High impedance characteristics for targeted frequency range filtering
Applications
- Signal line noise filtering in communication equipment
- Power supply decoupling in consumer electronics
- EMI suppression in industrial control systems
Procurement Notes
Verify that the ordered part number matches the specific impedance and current rating requirements for the target circuit. Confirm the package type is suitable for the manufacturing process. Ensure storage conditions comply with manufacturer guidelines to maintain material properties before soldering.
Selection Notes
Select this component based on the required impedance value at the target noise frequency. Consider the DC current rating to ensure the component does not saturate under operating conditions. Evaluate the physical dimensions to confirm fit within the designated footprint on the printed circuit board layout.
Part Context
This ferrite bead belongs to the MLS series, which offers various impedance values and current ratings. The series is designed for general-purpose EMI suppression in compact electronic devices. The 0805 package size balances performance with space constraints common in modern electronics manufacturing.
Replacement Considerations
Compatible substitutes include other 0805 ferrite beads with similar 120 Ohm impedance at 100 MHz and comparable current ratings. Verify that alternative parts meet the same DC resistance limits and package dimensions to ensure mechanical and electrical compatibility.
