MLS1206-4S7-202

Overview

The Ferroxcube MLS1206-4S7-202 is a multilayer EMI suppression ferrite bead in a 1206 (3216 Metric) surface-mount package. It features a monolithic structure designed for a closed magnetic path to enhance noise suppression efficiency. The component exhibits an impedance of 2 kOhms at 30 MHz and a maximum DC resistance of 600 milliohms. It supports a continuous current rating of 200 mA, making it suitable for protecting sensitive signal lines in compact electronic designs.

Feature Summary

• Monolithic construction providing a closed magnetic path for effective electromagnetic interference suppression
• High impedance characteristics optimized for high-frequency noise attenuation
• Surface-mount design compatible with automated assembly processes

Applications

• Motherboard signal line protection
• Notebook computer peripheral circuits
• CD-ROM and DVD-ROM drive interfaces
• Scanner data transmission lines

Procurement Notes

Verify the specific impedance tolerance and current derating curves against the official Ferroxcube datasheet before finalizing the design. Ensure the selected package size aligns with the PCB footprint guidelines provided by the manufacturer. Confirm that the operating temperature range meets the environmental requirements of the target application.

Selection Notes

Select this component when high-frequency noise suppression is required on low-current signal lines. The 200 mA rating limits its use to signal rather than power applications. Consider the 1206 package dimensions for space-constrained layouts. Evaluate the trade-off between impedance performance and DC resistance based on the specific circuit sensitivity.

Part Context

This part belongs to the MLS series of multilayer ferrite beads manufactured by Ferroxcube. These components are engineered for EMI suppression in digital and communication equipment. The 4S7 material grade provides specific magnetic properties tailored for broadband noise reduction in consumer electronics and computing peripherals.

Replacement Considerations

Check for direct substitutes from Ferroxcube with identical impedance and current ratings. Verify compatibility with other manufacturers' 1206 ferrite beads only if electrical parameters match exactly. Ensure any replacement maintains the same monolithic structure and package dimensions.
