Z0603C431FSMST

Overview

The KEMET Z0603C431FSMST is a surface-mount ferrite bead designed for signal line noise suppression. It features an impedance of 430 ohms at 100 MHz and supports a maximum DC current of 400 mA. The component has a typical DC resistance of 250 milliohms and utilizes a 0603 (1608 metric) package size.

Feature Summary

• Provides high-impedance attenuation for high-frequency noise on single signal lines
• Compact 0603 footprint suitable for space-constrained printed circuit board layouts
• Low DC resistance minimizes voltage drop and power loss in the signal path

Applications

• High-speed digital signal line filtering
• RF interference suppression in communication circuits
• Noise reduction on data transmission interfaces

Procurement Notes

Verify the specific suffix FS against the manufacturer's official datasheet to confirm impedance tolerance and terminal plating specifications. Ensure the selected variant matches the required current rating and impedance profile for the target application frequency range before finalizing procurement orders.

Selection Notes

Select this component when high attenuation is required at 100 MHz with limited current capacity. The low DC resistance preserves signal integrity while effectively damping high-frequency electromagnetic interference. Verify that the 400 mA current rating exceeds the peak operating current of the protected circuit.

Part Context

This ferrite bead belongs to the Z-series of chip beads manufactured by KEMET. These components are engineered for EMI suppression in compact electronic assemblies. The 0603 case size allows for automated surface-mount placement, supporting high-volume manufacturing processes for consumer and industrial electronics.

Replacement Considerations
