Z0805C250APWST

Overview

The KEMET Z0805C250APWST is a multilayer ferrite chip bead designed for surface-mount applications. It provides an impedance of 25 Ohms with a tolerance of 25% and supports a maximum DC current of 6 Amperes. The component features a low maximum DC resistance of 4 mOhms, ensuring minimal signal loss in high-current paths. It operates within a temperature range of -55°C to +125°C and utilizes a standard 0805 (2012 metric) package footprint.

Feature Summary

• High current handling capability suitable for power line filtering
• Low DC resistance minimizes voltage drop across the component
• Multilayer construction enables compact surface-mount integration

Applications

• Power supply output filtering
• DC-DC converter noise suppression
• High-current data line protection

Procurement Notes

Verify the specific suffix 'PWST' against official KEMET documentation to confirm packaging and tape specifications. Ensure the selected variant matches the required impedance and current ratings for the target circuit design before finalizing procurement.

Selection Notes

Select this component when high current capacity is required alongside moderate impedance values. The low DCR characteristic makes it appropriate for applications where maintaining voltage integrity under load is critical compared to higher resistance alternatives.

Part Context

This part belongs to the KEMET Z-SMS series of ferrite beads. It shares the 0805 form factor with other series members but differs in impedance and current ratings. The Z0805C250APWST is distinct from lower current variants like the Z0805C330ASMST due to its specialized high-current design.
