AFBC-SG0402-121T

Overview

The Abracon AFBC-SG0402-121T is a single-channel ferrite bead chip in the AFBC-SG0402 series. It features a 0402 (1005 metric) surface-mount package with an impedance of 120 ohms at 100 MHz and a DC current rating of 800 mA. The component has a maximum DC resistance of 300 milliohms, a tolerance of ±25%, and operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides high-frequency noise suppression for signal lines through ferrite material properties
• Designed for compact surface-mount integration in space-constrained circuit boards
• Supports continuous DC current up to 800 mA without saturation

Applications

• High-speed digital signal line filtering
• Power supply input/output decoupling
• RF interference suppression in portable electronics

Procurement Notes

Verify the specific suffix SG against the manufacturer's latest datasheet to confirm impedance characteristics and current ratings. Ensure the 0402 footprint matches the PCB land pattern. Confirm RoHS compliance status if required by assembly specifications. Cross-reference the 120 ohm value at 100 MHz with simulation models for accurate EMI performance prediction.

Selection Notes

Select this component when a low-profile 0402 ferrite bead is required for moderate current applications. The 800 mA rating suits general-purpose signal conditioning. Compare the 300 milliohm DCR against system power loss constraints. Ensure the operating temperature range meets environmental requirements for the target application.

Part Context

This part belongs to the AFBC-SG0402 series of ferrite beads from Abracon LLC. The series offers various impedance values in a standardized 0402 case size. These components are designed to attenuate high-frequency electromagnetic interference in electronic circuits while maintaining low DC resistance.

Replacement Considerations

Check for direct substitutes with identical 120 ohm impedance at 100 MHz and 800 mA current rating. Verify compatible 0402 footprint dimensions and terminal configurations. Ensure equivalent thermal and electrical performance metrics before substitution.
