Z0603C681CSMST

Overview

The KEMET Z0603C681CSMST is a multilayer ferrite chip bead designed for surface-mount applications. It provides an impedance of 680 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. It operates within a temperature range of -55°C to +125°C. The physical dimensions are 1.6 mm in length, 0.8 mm in width, and 0.8 mm in height, conforming to the 0603 (1608 metric) package standard.

Feature Summary

• Multilayer ferrite construction for high-frequency noise suppression
• Compact 0603 surface-mount form factor
• Flexible termination style for enhanced mechanical reliability

Applications

• High-speed data line filtering
• Power supply output filtering
• EMI suppression in compact electronic devices

Procurement Notes

Verify the specific impedance value against official datasheets, as part number suffixes can indicate variations. Confirm RoHS compliance status directly from the manufacturer's documentation. Ensure the selected packaging format matches production requirements. Check for end-of-life notifications or obsolescence warnings prior to finalizing procurement decisions.

Selection Notes

Select this component when a 680-ohm impedance at 100 MHz is required for signal integrity management. Evaluate the 300 mA current rating against circuit load conditions to prevent saturation. Consider the flexible termination option if board flexing is anticipated during operation or assembly processes.

Part Context

This ferrite bead belongs to the Z-SMS series from KEMET, which focuses on providing reliable EMI suppression solutions in small packages.
