Z0805C471BSMST

Overview

The KEMET Z0805C471BSMST is a multilayer ferrite chip bead designed for surface mount technology applications. It features an impedance of 470 ohms at 100 MHz and supports a maximum DC current rating of 500 mA. The component has a maximum DC resistance of 250 milliohms with a tolerance of 25 percent. It operates within a temperature range from -55 degrees Celsius to +125 degrees Celsius. The device utilizes a standard 0805 (2012 metric) package size, ensuring compatibility with automated assembly processes.

Feature Summary

• Provides effective signal line filtering through high impedance characteristics at 100 MHz
• Supports continuous DC currents up to 500 mA with low DC resistance
• Operates reliably across extended industrial temperature ranges

Applications

• Signal line filtering in electronic circuits
• Noise suppression in high-speed data lines
• EMI reduction in compact surface mount designs

Procurement Notes

Verify the specific ordering suffix and manufacturer part number against official KEMET documentation to ensure correct impedance and current ratings. Confirm availability status as distribution channels may vary. Check for any recent product change notices or lifecycle updates directly from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when signal integrity requires attenuation at 100 MHz while maintaining low insertion loss for DC paths. Ensure the circuit's DC bias does not exceed 500 mA to prevent saturation. Verify that the 0805 footprint aligns with the PCB layout constraints and thermal management requirements of the target application environment.

Part Context

This ferrite bead belongs to the Z-SMS series from KEMET, which focuses on compact noise suppression solutions. The series offers various impedance values tailored for different frequency domains. The Z0805C471BSMST specifically addresses mid-range interference scenarios where moderate current handling is required alongside significant high-frequency attenuation capabilities.

Replacement Considerations

Consult official KEMET substitution guides for direct equivalents. Cross-reference impedance curves and current ratings carefully when evaluating alternative manufacturers. Ensure physical dimensions match the existing 0805 footprint to maintain mechanical compatibility without redesigning the board.
