Z0201C471BSMST

Overview

The KEMET Z0201C471BSMST is a surface-mount ferrite bead from the Z-SMS series, designed for signal line noise suppression. It features a 0201 (0603 metric) package with a nominal impedance of 470 ohms at 100 MHz. The component supports a maximum DC current of 100 mA and exhibits a typical DC resistance of 1.05 ohms. Impedance tolerance is specified at ±25%. This device provides effective high-frequency attenuation in compact electronic designs.

Feature Summary

• Provides high-frequency noise suppression for sensitive signal lines
• Compact 0201 footprint suitable for space-constrained PCB layouts
• Low DC resistance minimizes voltage drop across the signal path

Applications

• High-speed digital signal line filtering
• RF circuit noise attenuation
• Data bus protection in compact modules

Procurement Notes

Verify the specific suffix and tape/reel specifications against the manufacturer's latest datasheet to ensure compatibility with automated assembly processes. Confirm that the 100 mA current rating aligns with the operational requirements of the target circuit to prevent performance degradation or thermal issues during procurement.

Selection Notes

Select this component when space constraints necessitate a 0201 package size while requiring significant impedance for noise control. Ensure the operating current remains below the 100 mA limit to maintain stable impedance characteristics. Consider the 1.05 ohm DC resistance impact on signal integrity compared to lower-resistance alternatives if voltage drop is a critical design parameter.

Part Context

This ferrite bead belongs to KEMET's Z-SMS series, which focuses on miniaturized components for modern electronics. The 0201 form factor represents a standard small outline package widely used in consumer and industrial electronics where board real estate is limited. It serves as a passive filter element within broader electromagnetic interference mitigation strategies.

Replacement Considerations

Consult official KEMET documentation for direct cross-references. Verify that any substitute part matches the 470 ohm impedance, 100 mA current rating, and 0201 dimensions to ensure mechanical and electrical compatibility without redesigning the PCB layout.
