AFBC-Q0402-221-T

Overview

The AFBC-Q0402-221-T is a surface-mount ferrite bead manufactured by Abracon LLC. It features a compact 0402 (1005 metric) package designed for high-density circuit board layouts. The component provides an impedance of 220 ohms at 100 MHz, serving as a key element in electromagnetic interference suppression circuits. It operates with a DC resistance of 0.35 ohms maximum and supports a rated current of 800 mA. These specifications define its electrical performance characteristics within signal filtering applications.

Feature Summary

• Provides effective attenuation of high-frequency noise signals across sensitive data lines
• Utilizes a compact footprint to support dense surface-mount assembly requirements
• Maintains low DC resistance to minimize power loss in the signal path

Applications

• High-speed digital interface noise suppression
• Power supply line filtering for integrated circuits
• RF signal integrity enhancement in communication modules

Procurement Notes

Verify the specific suffix codes against official Abracon documentation to ensure correct impedance tolerance and packaging configuration. Confirm that the requested quantity matches the standard reel size specified in the manufacturer's datasheet. Cross-reference the date code and lot traceability requirements with your quality assurance standards before finalizing the purchase order.

Selection Notes

Select this component when space constraints necessitate a 0402 package size while requiring significant impedance at 100 MHz. Evaluate the DC bias current requirements to ensure the 800 mA rating exceeds the operational load. Consider the thermal dissipation capabilities inherent to the small form factor during continuous operation.

Part Context

This part belongs to Abracon's series of passive components designed for EMI suppression. Ferrite beads in this category are essential for maintaining signal integrity in modern electronic devices. The product line emphasizes miniaturization without compromising filtering efficiency for portable and industrial electronics.

Replacement Considerations

Consult official cross-reference lists for equivalent parts from other manufacturers. Ensure substitute components match the 0402 package dimensions and 220 ohm impedance at 100 MHz. Verify that alternative suppliers provide identical current ratings and DC resistance specifications.
