Z0805C101ASMST

Overview

The KEMET Z0805C101ASMST is a multilayer ferrite chip bead designed for surface-mount technology in the 0805 package. It provides an impedance of 100 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The component supports a maximum DC current of 900 mA and maintains a maximum DC resistance of 100 mOhms. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Multilayer construction for compact surface-mount integration
• High impedance performance for high-frequency noise suppression
• Robust current handling capability for power line applications

Applications

• High-speed data line filtering
• Power supply noise attenuation
• EMI suppression in digital circuits

Procurement Notes

Verify end-of-life status and availability through authorized distributors. Confirm RoHS compliance details and specific packaging requirements such as reel or cut tape options before ordering. Ensure the selected variant matches the required impedance and current ratings for the target application circuit.

Selection Notes

Select this component when a 100 Ohm impedance at 100 MHz is required in a 0805 footprint. Verify that the 900 mA current rating meets the circuit's DC load requirements. Consider the 100 mOhms DCR for voltage drop calculations. Ensure the operating temperature range aligns with the environmental conditions of the final assembly.

Part Context

This ferrite bead belongs to the Z-SMS series from KEMET, which focuses on multilayer chip beads for general-purpose EMI suppression. The 0805 case size offers a balance between current handling capacity and board space efficiency compared to smaller packages.
