AFBC-Q3211-300-T

Overview

The AFBC-Q3211-300-T is a ferrite bead from the Abracon AFBC-Q3211 series, designed for high-current applications. It features a 1206 (3216 metric) surface-mount package with an impedance of 30 ohms at 100 MHz. The component supports a maximum DC current of 3 A and has a maximum DC resistance of 40 milliohms. Impedance tolerance is specified at ±25%. It operates within a temperature range of -55°C to +150°C.

Feature Summary

• High-current capability suitable for automotive signal lines
• Low DC resistance for minimal power loss
• Automotive-grade reliability in a compact 1206 footprint

Applications

• Automotive signal line filtering
• High-current DC power rail noise suppression
• EMI suppression in automotive electronics

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging if required by assembly equipment. Confirm RoHS compliance status through the official datasheet or manufacturer documentation before integration. Ensure the 1206 package dimensions align with the PCB footprint design rules.

Selection Notes

Select this component when high current handling up to 3 A is required alongside EMI suppression. The low DC resistance minimizes voltage drop across the filter. Verify that the 30-ohm impedance at 100 MHz meets the target noise frequency requirements for the specific circuit application.

Part Context

This part belongs to the Abracon AFBC-Q3211 series of high-current ferrite beads. The series is specifically engineered for automotive applications requiring robust performance under varying thermal conditions. The 1206 case size provides a balance between current capacity and board space efficiency.

Replacement Considerations

Check for other parts in the AFBC-Q3211 series with different impedance values if noise characteristics differ. Verify physical compatibility with existing footprints when considering alternative manufacturers.
