NCB-H0805A101TR400F

Overview

The NCB-H0805A101TR400F is a high-current ferrite chip bead manufactured by NIC Components Corp. It features a 0805 (2012 Metric) case size with an impedance of 100 ohms at 100 MHz and a DC resistance of 20 milliohms. The component supports a maximum current of 4 amperes and operates within a temperature range of -40 °C to 125 °C. Its physical height is 1.1 mm, and it complies with RoHS standards.

Feature Summary

• High current handling capability up to 4 amperes
• Low DC resistance for minimal signal loss
• Compact 0805 surface mount footprint

Applications

• Power line noise suppression
• High current circuit filtering
• EMI suppression in compact electronics

Procurement Notes

Verify the specific impedance tolerance and current ratings against the official datasheet before integration. Confirm that the operating temperature range meets the environmental requirements of the target application. Ensure compatibility with standard reflow soldering profiles for 0805 components.

Selection Notes

Select this component when low DC resistance and high current capacity are critical alongside EMI suppression. The 0805 package offers a balance between current handling and board space efficiency. Consider the 100 MHz impedance characteristic for the specific frequency range of interference to be mitigated.

Part Context

This ferrite bead belongs to the NCB-H series from NIC Components Corp, designed specifically for high-current applications. The series utilizes materials optimized for effective noise absorption while maintaining low power loss. It serves as a passive component for managing electromagnetic interference in dense electronic assemblies.

Replacement Considerations

Direct substitutes must match the 100-ohm impedance at 100 MHz, 4-ampere current rating, and 0805 package dimensions. Verify thermal characteristics and DC resistance limits to ensure equivalent performance in the existing circuit design.
