AFBC-SG0402-221T

Overview

The AFBC-SG0402-221T is a surface-mount ferrite bead from the Abracon AFBC-SG0402 series, designed for high-frequency noise suppression in compact electronic circuits. It features a 0402 (1005 metric) package with dimensions of 1 mm length, 0.5 mm width, and 0.5 mm height. The component provides an impedance of 220 Ohms at its rated frequency, with a maximum DC resistance of 400 mOhms and a current rating of 700 mA. It operates within a temperature range of -40°C to +85°C.

Feature Summary

• Provides effective attenuation of high-frequency electromagnetic interference signals
• Compact 0402 surface-mount footprint suitable for space-constrained designs
• Low DC resistance minimizes voltage drop across power lines
• High current handling capability supports stable operation under load

Applications

• Noise filtering on power supply lines for integrated circuits
• EMI suppression in portable consumer electronics
• Signal integrity enhancement in high-speed digital circuits

Procurement Notes

Verify the specific suffix 'SG' against the manufacturer's official datasheet to confirm impedance tolerance and current ratings, as variations exist within the AFBC-SF/SQ/SG families. Ensure the ordering code matches the required 220 Ohm specification and 0402 package size. Confirm RoHS compliance status through the latest production documentation before finalizing procurement.

Selection Notes

Select this component when a low-profile ferrite bead with moderate current capacity is required for EMI reduction. The 220 Ohm impedance value targets specific noise frequencies; verify this aligns with the target noise spectrum. The 700 mA rating must exceed the maximum DC current of the protected circuit line to prevent saturation or excessive heating during normal operation.

Part Context

This part belongs to the Abracon AFBC-SG0402 series of chip ferrite beads. These components are passive devices used primarily for signal conditioning and noise suppression. The series offers various impedance values and current ratings within the standard 0402 case size, allowing designers to tailor filtering characteristics without increasing board space.

Replacement Considerations

Cross-reference with other 0402 ferrite beads offering 220 Ohms impedance and similar current ratings. Verify pin compatibility and thermal performance if substituting with parts from different manufacturers. Ensure the replacement maintains the same operating temperature range and physical dimensions.
