AFBC-Q0805H-301-T

Overview

The AFBC-Q0805H-301-T is a surface-mount ferrite bead from the Abracon AFBC-Q0805H series, designed for high-current applications. It features an impedance of 300 Ohms at 100 MHz and supports a maximum DC current of 1 Ampere. The component exhibits a maximum DC resistance of 0.04 Ohms. Housed in an 0805 (2012 Metric) package with dimensions of 2.0mm length, 1.25mm width, and 0.85mm height, it operates within a temperature range of -55°C to +125°C.

Feature Summary

• Provides effective electromagnetic interference suppression through high impedance characteristics at target frequencies
• Engineered for high-current handling capabilities suitable for power line filtering
• Utilizes robust ferrite material construction for stable performance across wide temperature ranges

Applications

• Power supply output filtering
• High-speed digital signal line noise suppression
• Communication equipment EMI reduction

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status against current manufacturer declarations. Ensure the selected variant matches the required 300 Ohm impedance specification for the intended frequency band. Cross-reference the 1A current rating with circuit requirements to prevent saturation.

Selection Notes

Select this component when a 300 Ohm impedance at 100 MHz is required for noise attenuation. The 1A current rating makes it suitable for power rails where lower impedance beads would saturate. The 0805 footprint offers a balance between current capacity and board space. Consider the 0.04 Ohm DC resistance impact on voltage drop for sensitive loads.

Part Context

This part belongs to the AFBC-Q0805H series, which focuses on high-performance ferrite beads for demanding electronic environments. The series provides various impedance values within the standard 0805 package, allowing designers to tailor noise suppression without changing the physical footprint. It complements other passive components in complex filtering networks.

Replacement Considerations

Direct substitutes include AFBC-Q0805H-471-T for higher impedance needs or AFBC-Q0805H-102-T for different frequency profiles. Verify that any replacement maintains the 1A current rating and 0805 package dimensions to ensure mechanical compatibility.
