CST14/6.4/29-3N2

Chip Ferrite Bead Overview

The Ferroxcube CST14/6.4/29-3N2 is a cylindrical ferrite core designed for cable shielding and EMI suppression applications. It utilizes the 3N2 soft ferrite material, which provides high permeability suitable for low-frequency noise attenuation. The component features a tubular geometry with an outer diameter of 14.3 mm, an inner diameter of 6.35 mm, and a length of 28.6 mm. It exhibits an impedance of 250 ohms at 100 MHz, ensuring effective common-mode noise reduction for cables passing through its central aperture.

Chip Ferrite Bead Feature Summary

• Cylindrical tubular design facilitates easy installation over existing cables without disconnection.
• High permeability 3N2 material composition optimized for low-frequency electromagnetic interference suppression.
• Provides significant impedance to attenuate common-mode noise signals on conductors.

Chip Ferrite Bead Applications

• Electromagnetic interference (EMI) suppression on data and power cables
• Common-mode noise filtering in electronic equipment wiring
• Signal integrity enhancement for communication lines

Chip Ferrite Bead Procurement Notes

Verify that the specified 3N2 material grade matches the target frequency requirements for noise attenuation. Confirm physical dimensions align with cable outer diameters to ensure proper fit. Check RoHS compliance status if required by specific regulatory frameworks. Ensure ordering suffixes correspond to the exact bulk packaging configuration needed for production integration.

Chip Ferrite Bead Selection Notes

Select this component when high permeability is required for low-frequency noise environments. The 3N2 material offers superior performance compared to standard materials in specific frequency bands. Evaluate the 250-ohm impedance characteristic against the noise spectrum to confirm adequate attenuation levels. Consider the physical size constraints relative to the cable bundle diameter during mechanical design.

Chip Ferrite Bead Part Context

This part belongs to the CST series of cylindrical ferrite cores manufactured by Ferroxcube. These components are widely used in passive EMI suppression solutions. The naming convention indicates the dimensional code, inner diameter, length, and specific ferrite material formulation used for the magnetic properties.

Chip Ferrite Bead Replacement Considerations

Substitute parts must match the 14.3 mm outer diameter, 6.35 mm inner diameter, and 28.6 mm length. Equivalent 3N2 material grade is required to maintain identical permeability and impedance characteristics. Verify that alternative suppliers offer the same 250-ohm impedance specification at 100 MHz.
