Z0805C221APMST

Overview

The KEMET Z0805C221APMST is a surface-mount ferrite bead designed for EMI suppression in high-current applications. It features a 220-ohm impedance at 100 MHz and supports a continuous current rating of 2000 mA. The component exhibits a low DC resistance of 50 milliohms, ensuring minimal signal loss. Housed in an 0805 (2012 metric) package with dimensions of 2.00 mm by 1.25 mm, it provides effective noise filtering for power lines and data interfaces.

Feature Summary

• Provides effective electromagnetic interference suppression for sensitive circuits
• Supports high continuous current operation with low insertion loss
• Compact surface-mount design suitable for dense PCB layouts

Applications

• Power line noise filtering in portable electronics
• EMI suppression in automotive infotainment systems
• Signal integrity protection in industrial communication interfaces

Procurement Notes

Verify the specific impedance tolerance and DC resistance values against the official KEMET datasheet prior to integration. Confirm that the 0805 package footprint matches the target PCB land pattern. Ensure the selected supplier provides traceable documentation confirming compliance with RoHS directives and material safety standards required for the final assembly process.

Selection Notes

Select this component when circuit design requires significant current handling capability alongside noise attenuation. The low DC resistance minimizes voltage drop across the filter, making it suitable for power rails where efficiency is critical. Evaluate the thermal performance under maximum load conditions to ensure reliable operation within the specified temperature range without derating issues.

Part Context

This ferrite bead belongs to KEMET's Z-PMS series of SMD chip noise suppressors. The series is engineered for general-purpose EMI suppression in consumer and industrial electronics. The 0805 form factor balances physical size with current-carrying capacity, offering a robust solution for space-constrained designs requiring reliable noise filtration on high-current traces.
