AFBC-SF0402-461T

Overview

The AFBC-SF0402-461T is a surface-mount ferrite bead from the Abracon AFBC-SF0402 series, designed for electromagnetic interference (EMI) suppression in compact electronic circuits. Housed in a standard 0402 (1005 metric) package, this component provides an impedance of 460 ohms at its rated frequency with a maximum DC current rating of 900 mA. It features a low maximum DC resistance of 170 mohms and a tolerance of ±25%. The device operates reliably within a temperature range of -40°C to +85°C, making it suitable for various consumer and industrial applications requiring effective noise filtering.

Feature Summary

• Provides high impedance to suppress high-frequency electromagnetic interference signals
• Compact 0402 surface-mount footprint enables integration into space-constrained designs
• Low DC resistance minimizes power loss and voltage drop in signal paths
• Robust construction supports operation across extended industrial temperature ranges

Applications

• Power supply input and output filtering
• Battery charger circuit protection
• Portable electronic device noise suppression
• Energy-efficient system signal integrity enhancement

Procurement Notes

Verify the specific impedance value and current rating against your schematic requirements before ordering. Confirm that the 0402 package dimensions align with your PCB land pattern. Ensure the operating temperature range meets your environmental specifications. Check RoHS compliance status if required by your manufacturing standards. Validate supplier authenticity through authorized distribution channels.

Selection Notes

Select this component when space constraints necessitate a 0402 package size while requiring significant EMI suppression capabilities. Consider the 900 mA current rating to ensure it exceeds the maximum expected DC load current without saturation. Evaluate the 170 mohm DC resistance to confirm it does not cause unacceptable voltage drops in sensitive circuits. Compare impedance characteristics against alternative ferrite beads to ensure optimal noise attenuation at target frequencies.

Part Context

This ferrite bead belongs to Abracon's AFBC-SF0402 series, which focuses on providing reliable EMI filtering solutions in miniature packages. The series is engineered for modern electronics where board real estate is limited but noise immunity remains critical. Similar components in this family offer varying impedance and current ratings to suit different circuit demands while maintaining consistent physical dimensions for design flexibility.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering similar 460 ohm impedance and 900 mA current ratings. Verify package compatibility and electrical parameters match original specifications. Consult manufacturer substitution guides for equivalent performance alternatives.
