AFBC-SF0402-331T

Overview

The AFBC-SF0402-331T is a surface-mount ferrite bead from the Abracon AFBC-SF0402 series, housed in a 0402 (1005 metric) package. It provides an impedance of 330 Ohms at 900 MHz with a tolerance of ±25%. The component supports a maximum DC current rating of 650 mA and features a maximum DC resistance (DCR) of 300 mOhms. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides high-frequency noise suppression through ferrite material properties
• Designed for surface-mount assembly using SMD/SMT termination styles
• Shielded construction to contain magnetic fields

Applications

• High-speed data line filtering
• Power supply noise attenuation
• RF circuit interference reduction

Procurement Notes

Verify the specific impedance frequency and current ratings against your circuit requirements before ordering. Confirm that the 0402 package dimensions fit your PCB layout constraints. Ensure the operating temperature range meets your environmental specifications. Check RoHS compliance status if required by your manufacturing standards.

Selection Notes

Select this component when space-constrained designs require effective high-frequency noise filtering. The 0402 footprint allows for dense board layouts. Consider the 650 mA current rating to ensure the component does not saturate under normal operating conditions. The low DCR minimizes voltage drop across the filter.

Part Context

This part belongs to the AFBC-SF0402 series of ferrite beads manufactured by Abracon LLC. These components are passive devices used primarily for electromagnetic interference (EMI) suppression in electronic circuits. The series offers various impedance values to suit different frequency applications while maintaining a compact form factor suitable for modern electronics.

Replacement Considerations

Check for compatible ferrite beads from other manufacturers with identical 0402 footprints and similar impedance characteristics at 900 MHz. Ensure substitute parts meet or exceed the 650 mA current rating and 300 mOhm DCR limits. Verify thermal performance matches the -40°C to +85°C range.
