Ferrite cores are materials used for impedance matching, to reduce EMI emissions, and to increase the voltage and current ratings of electric cables and wiring. The SB28B0617 is an example of such a core – made of Nickel-zinc ferrite. The SB28B0617 core components are cylindrical in shape, and measure 39.5 mm in length and 6.9 mm in diameter, allowing them to fit conveniently into most power cables and wiring. They are designed for use in medium- to high-power applications, with a maximum current rating of 32 A.

The most significant feature of the SB28B0617 is its excellent high frequency emission and attenuation characteristics. This is due to the fact that the SB28B0617 core is made of Nickel-zinc ferrite, which has a low reactance and permeability that is much better than traditional ferrite materials such as iron-silicon-aluminum. This makes the SB28B0617 an ideal choice for controlling high frequency EMI emissions. This ferrite core is also very effective when used as an inductor or choke in switching power supplies, as it provides a very high inductance per unit volume.

In addition, the SB28B0617 offers excellent electrical isolation characteristics. Its nickel-zinc ferrite material is highly resistant to electric breakdown, and its design ensures that it has high dielectric strength and effective insulation. This makes it an ideal choice for applications such as interlocking power cables and reducing EMI electromagnetic interference.

When it comes to applications involving ferrite cores, the SB28B0617 core is designed to work in a variety of scenarios. It can be used in cable and wiring assemblies such as power cables, optical cable assemblies, bonding cables, and transformer windings. It can also be used for flexible AC adapters, EMI shielding, and current-limiting components such as inrush current suppressors.

As for the working principle of the SB28B0617 core, its design and construction are based on the concept of core-casting. This means that the core is composed of an assembly of small, uniform ferrite segment parts that are magnetically joined to form a single unit. The core material includes a combination of ferrite and binder that are designed to create an ideal magnetic path throughout the core. This magnetic path enables the core to conduct a magnetic field without allowing any stray flux to escape. This helps to reduce EMI emissions, improve electrical efficiency, and increase current ratings.

The SB28B0617 is an excellent choice for a wide range of applications, as it provides superior high frequency EMI emissions and attenuation performance, and excellent electrical isolation properties. It can also be used in cable and wiring assemblies, flexible AC adapters, and current-limiting components.
