Z0805C121ASMST

Overview

The KEMET Z0805C121ASMST is a surface-mount ferrite bead designed for signal line filtering in the 0805 (2012 metric) package. It provides an impedance of 120 Ohms at 100 MHz with a maximum DC resistance of 150 milliohms and a rated current of 800 mA. The component operates within a temperature range of -55°C to +125°C and complies with RoHS3 standards.

Feature Summary

• Provides high impedance attenuation for signal lines at 100 MHz
• Supports continuous currents up to 800 mA
• Operates reliably across extended industrial temperature ranges

Applications

• Signal line noise suppression
• High-frequency interference filtering
• Compact surface-mount circuit protection

Procurement Notes

Verify component status as this part may be discontinued or subject to production changes. Confirm availability through authorized distributors and check for official product change notices. Ensure the specific ordering suffix matches design requirements before finalizing procurement plans.

Selection Notes

Select this component for applications requiring compact signal filtering with moderate current handling. The 0805 footprint suits space-constrained designs. Verify that the 120 Ohm impedance profile aligns with target frequency noise characteristics and that the 800 mA rating exceeds operational peak currents.

Part Context

This ferrite bead belongs to the Z-SMS series, which focuses on high-performance signal conditioning. The Z0805C base designation indicates the 0805 form factor and magnetic material composition. This series supports general-purpose electronic filtering needs in commercial and industrial hardware.
