HCB 2012KF-301T30

Chip Ferrite Bead Overview

The HCB2012KF-301T30 is a surface-mount power line ferrite bead manufactured by TAI-TECH Advanced Electronics Co., Ltd. in the 0805 (2012 metric) package. It exhibits an impedance of 300 ohms at 100 MHz and supports a maximum rated current of 3 amperes with a maximum DC resistance of 40 milliohms. The component provides one circuit path for EMI suppression.

Chip Ferrite Bead Feature Summary

• Provides high impedance to attenuate electromagnetic interference signals at 100 MHz
• Supports high current loads up to 3 amperes for power line applications
• Features low DC resistance to minimize voltage drop and power loss

Chip Ferrite Bead Applications

• Power line filtering in electronic circuits
• EMI suppression on signal lines requiring high current handling

Chip Ferrite Bead Procurement Notes

Verify the complete part number includes the suffix 'T30' to confirm the specific packaging configuration. Ensure the procurement documentation explicitly lists the manufacturer as TAI-TECH Advanced Electronics Co., Ltd. to avoid substitution with generic equivalents that may lack the specified 3A current rating or 300 Ohm impedance characteristics.

Chip Ferrite Bead Selection Notes

Select this component when circuit design requires EMI filtering on lines carrying currents up to 3 Amperes. The 0805 footprint is suitable for space-constrained layouts. Verify that the target frequency range aligns with the 300 Ohm impedance specification at 100 MHz to ensure effective noise attenuation without excessive signal degradation.

Chip Ferrite Bead Part Context

This ferrite bead belongs to the HCB series from TAI-TECH, which focuses on high-current chip inductors. The series utilizes advanced magnetic materials to achieve low DC resistance while maintaining high impedance for noise suppression. It serves as a passive component for protecting sensitive electronics from conducted interference.

Chip Ferrite Bead Replacement Considerations

Substitutes must match the 0805 package, 300 Ohm @ 100 MHz impedance, and 3A current rating. Verify DC resistance does not exceed 40 milliohms to maintain thermal performance.
