Z0402C601ASMST

Overview

The KEMET Z0401C601ASMST is a multi-layer ferrite chip bead from the Z-SMS series, designed for signal line noise suppression. It features an impedance of 600 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current rating of 300 mA and exhibits a maximum DC resistance (DCR) of 0.58 Ohms. Housed in a compact 0402 (1005 metric) surface-mount package, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective high-frequency noise attenuation for sensitive signal lines through multi-layer ferrite construction.
• Offers reliable performance under varying thermal conditions with a wide operating temperature range.
• Designed for space-constrained applications utilizing a standard 0402 surface-mount footprint.

Applications

• High-speed digital signal line filtering
• RF circuit noise suppression
• Data bus protection

Procurement Notes

Verify the specific suffix 'ASMST' against the manufacturer's official datasheet to confirm terminal finish and packaging configuration. Confirm availability status as end-of-life or obsolescence notices may apply to this series. Ensure the selected variant matches the required impedance and current ratings for the target application circuit.

Selection Notes

Select this component when a 600 Ohm impedance at 100 MHz is required for signal integrity management. Evaluate the 300 mA current rating to ensure it exceeds the peak DC bias of the protected line. Consider the 0.58 Ohm DCR impact on signal loss and power dissipation in low-voltage logic circuits.

Part Context

This part belongs to the KEMET Z-SMS series of ferrite beads, which are engineered for general-purpose EMI suppression in compact electronic assemblies. The 0402 case size allows for high-density PCB layouts common in modern consumer and industrial electronics.

Replacement Considerations

Consult official substitution guides for equivalent 600 Ohm, 300 mA ferrite beads in 0402 packages. Verify that alternative components match the impedance profile at 100 MHz and maintain compatible thermal and current handling capabilities.
