Ferrite coil energy storage inductor

What are ferrite core inductors?

Ferrite core inductors are one of three types of inductors commonly found on the market, besides air core and iron core inductors. The purpose of an inductor is to store electrical energy in a magnetic field as currents flow through it. The magnetic field is generated from currents flowing through a coil.

What type of energy does a ferrite core inductor store?

Ferrite core inductor works by allowing the flow of current to generate a magnetic field & the change within the magnetic field results in the flowing of an opposing current. So they change the energy from electrical to magnetic and store the energy within them.

Do ferrite core inductors have high permeability?

Ferrite core inductors have high permeability, with the range generally ranging from 1400 to 15,000 based on the ferrite material type utilized. This results in high inductance compared to other types of inductors, such as air core inductors.

Are ferrite core inductors better than air core?

The air core and iron core inductors carry low inductance, minimal frequency operations, and higher losses. However, ferrite core inductors have a fixed value, high permeability, and high inductance. Therefore, ferrite core inductors are popular and considered a better way out to avoid this problem.

What frequency range do ferrite core inductors operate in?

Ferrite core inductors are utilized in coils that are activated in between an AF to 100 MHZ frequency range. The applications of ferrite core inductors include the following. Ferrite core inductors are mainly used in different electric circuit applications like broadband, power conversion & interference suppression.

Why do ferrite core inductors have low eddy currents?

Since the material has low electrical conductivity, it keeps eddy currents low. Ferrite core inductors are a cost-effective alternative to air core or iron core inductors, which can only handle limited frequencies. The use of the magnetic material ferrite core allows for more frequencies with minimal eddy current losses.
