Z0603C601ASMST

Overview

The KEMET Z0603C601ASMST is a single-line ferrite chip bead designed for surface-mount technology in the 0603 (1608 metric) package. It provides an impedance of 600 ohms at 100 MHz with a maximum DC resistance of 450 milliohms and a rated current of 350 mA. The component operates within a temperature range of -55°C to +125°C and features a 25% impedance tolerance.

Feature Summary

• Provides high-frequency noise suppression through significant impedance at 100 MHz
• Compact 0603 surface-mount footprint suitable for space-constrained designs
• Capable of handling continuous DC currents up to 350 mA

Applications

• EMI filtering on power supply lines
• Signal line noise attenuation in digital circuits
• High-frequency interference suppression in compact electronic modules

Procurement Notes

Verify the specific datasheet revision and manufacturer lifecycle status before procurement, as this component may be subject to obsolescence or discontinuation notices. Confirm that the 350 mA current rating aligns with the application's peak and steady-state requirements to prevent thermal failure. Ensure compatibility with standard reflow soldering profiles for the 0603 package.

Selection Notes

Select this component when a 600-ohm impedance at 100 MHz is required for EMI suppression in low-current applications. The 0603 size offers a balance between performance and board space. Consider the 450-milliohm DCR impact on voltage drop if used in sensitive power rails. Verify that the 350 mA current limit exceeds the circuit's maximum operating current under all conditions.

Part Context

This part belongs to the KEMET Z-SMS series of ferrite beads, which are engineered for general-purpose EMI suppression. The series utilizes stable ferrite materials to maintain consistent impedance characteristics across the specified temperature range. The 0603 form factor allows for automated placement in high-volume manufacturing environments.

Replacement Considerations
