Additional Information

Ferrite beads are essentially single-turn structure devices made of lossy ferrite materials, equivalent to a resistor in series with an inductor. At low frequencies, they are primarily inductive, while at high frequencies, the resistive component increases sharply and becomes dominant, effectively absorbing noise energy and converting it into heat. Their operating frequency range depends on the specific ferrite material grade and model. Ferrite cores generally refer to various core structures made of low-loss ferrite materials, commonly used in transformers, high-frequency inductors, common-mode chokes, and similar components. When used as magnetic cores for inductive components, the material is typically required to have minimal losses, which is contrary to the intentionally high losses sought in ferrite beads.
