Z0603C680CSMST

Overview

The KEMET Z0603C680CSMST is a multilayer ferrite chip bead designed for signal line noise suppression in surface-mount applications. It features an impedance of 68 ohms at a test frequency of 100 MHz with a tolerance of ±25%. The component supports a maximum DC current of 300 mA and exhibits a maximum DC resistance of 350 milliohms. Housed in a standard 0603 (1608 metric) package measuring 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height, it operates reliably within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction provides compact noise filtering for high-density circuit boards
• Optimized for signal line interference reduction in sensitive electronic circuits
• Capable of handling specified DC bias currents without significant performance degradation

Applications

• Signal line noise suppression in consumer electronics
• EMI filtering in portable communication devices
• Noise control in automotive infotainment systems

Procurement Notes

Verify the current lifecycle status before procurement, as official sources indicate this specific part number may be obsolete or subject to discontinuation by the manufacturer. Confirm availability through authorized distributors and check for valid RoHS compliance documentation. Ensure that the 0603 footprint matches the target design constraints and that the 300 mA current rating meets the application requirements.

Selection Notes

Select this component when a 68-ohm impedance at 100 MHz is required for signal integrity management. The 0603 package size suits space-constrained designs. Verify that the 300 mA current rating aligns with the operating conditions and that the -55°C to +125°C temperature range covers the environmental exposure. Consider the 350 milliohm DC resistance impact on signal loss if applicable.

Part Context

This ferrite bead belongs to the Z-SMS series from KEMET, which focuses on multilayer chip beads for general-purpose noise suppression. The series utilizes ceramic ferrite materials to provide effective attenuation across a broad frequency spectrum while maintaining a small form factor suitable for modern surface-mount technology assembly processes.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source data. Consult the manufacturer's official cross-reference tools or datasheets for verified alternatives that match the 68-ohm impedance, 0603 package, and 300 mA current specifications.
