MLS0805-4S4-202

Overview

The Ferroxcube MLS0805-4S4-202 is a surface-mount ferrite bead designed for signal line filtering. It utilizes the 4S4 soft ferrite material and is housed in an 0805 [2012 Metric] case style. The component provides an impedance of 120 Ohms at 100 MHz with a tolerance of ±25%. It supports a DC current rating of 600 mA and exhibits a maximum DC resistance of 0.05 Ohms. This device functions as a single-function data line filter to suppress electromagnetic interference.

Feature Summary

• Provides high impedance attenuation for high-frequency noise suppression on data lines
• Designed for compact surface-mount integration using standard 0805 packaging
• Constructed from specialized soft ferrite material optimized for broadband filtering

Applications

• High-speed digital signal line filtering
• Data bus noise suppression
• Electromagnetic interference (EMI) mitigation in portable electronics

Procurement Notes

Verify the specific impedance value and current rating against the official manufacturer datasheet prior to procurement. Confirm that the 4S4 material grade aligns with the target frequency response requirements. Ensure the 0805 footprint matches the PCB layout constraints. Check for RoHS compliance status if required by the end product specifications.

Selection Notes

Select this component when space-constrained designs require effective high-frequency noise reduction without adding significant series resistance. The 600 mA rating suits low-power signal lines rather than power delivery paths. Consider the ±25% impedance tolerance when designing strict noise margin budgets. Evaluate thermal performance under continuous DC bias conditions to ensure stable operation.

Part Context

This part belongs to the Ferroxcube MLS series of surface-mount ferrite beads. These components are engineered for use in consumer electronics and communication devices where small form factors are critical. The series offers various impedance values and current ratings to accommodate different circuit protection needs across multiple industries.

Replacement Considerations

Consult official Ferroxcube documentation for direct cross-references. Verify that any substitute maintains identical 0805 dimensions, 600 mA current handling, and comparable impedance characteristics at 100 MHz to ensure circuit compatibility.
