NCB-H0805A221TR300F

Overview

The NCB-H0805A221TR300F is a surface-mount ferrite bead from NIC Components Corp, designed for power line noise suppression in the 0805 (2012 Metric) package. It exhibits an impedance of 220 Ohms at 100 MHz and supports a maximum current rating of 3 Amperes. The component features a low DC resistance of 40 milliohms to minimize signal loss. It is RoHS compliant and suitable for high-frequency EMI filtering applications.

Feature Summary

• Provides effective electromagnetic interference suppression on power lines
• Maintains low DC resistance for efficient power transmission
• Supports high current handling capabilities up to 3 Amperes

Applications

• Power supply input filtering
• High-speed digital circuit noise suppression
• EMI reduction in portable electronic devices

Procurement Notes

Verify the specific impedance tolerance and current derating curves against the official datasheet before finalizing the design. Confirm that the 0805 package dimensions align with the target PCB footprint. Ensure the selected variant meets all required environmental and reliability standards for the intended operating conditions.

Selection Notes

Select this component when a compact solution is required for suppressing high-frequency noise on power rails carrying moderate currents. The 220 Ohm impedance at 100 MHz targets common switching noise frequencies. Consider the 40 milliohm DC resistance impact on voltage drop if the load current approaches the 3 Ampere limit.

Part Context

This ferrite bead belongs to the NCB series of passive components manufactured by NIC Components Corp. The series offers various impedance values and current ratings in standard metric case sizes. These components are engineered for integration into modern electronics requiring reliable EMI management without significant size penalties.

Replacement Considerations

Direct substitutes must match the 220 Ohm @ 100 MHz impedance, 3A current rating, and 0805 package. Verify equivalent DC resistance and saturation characteristics to ensure identical performance in the specific circuit topology.
