The difference in the size of energy storage inductors

How does inductor size affect energy storage?

Different core materials can store different amounts of magnetic energy per volume, but within the same core material, inductor size is largely dictated by energy storage. The energy a inductor can store, in common units, is: J = ½ A 2 H where J is the energy in Joules, A the current thru the inductor in Amps, and H the inductance in Henrys.

How much energy can a inductor store in common units?

The energy a inductor can store, in common units, is: J = ½ A 2 H where J is the energy in Joules, A the current thru the inductor in Amps, and H the inductance in Henrys. Look at a family of inductors that all use the same core, and you will see that the maximum energy storage is about the same across the family.

Does size matter in power inductors?

Look at a family of inductors that all use the same core, and you will see that the maximum energy storage is about the same across the family. For example, here are the specs for the CoilCraft MSS6132 series of power inductors: Pick a few and compute their energy storage at the 10% drop saturation level. For example: So yes, size matters.

How does an inductor store energy?

An inductor is a component, in electronics that stores energy by creating a field when electricity flows through it. It consists of a coil of wire wound around a core made of materials such as iron or ferrite. When current runs through the coil it generates a field that retains energy.

What are capacitors & inductors?

Capacitors and inductors are important components in electronic circuits and each of them serve unique functions. Capacitors store energy in an electric field, while inductors store energy in a magnetic field. They have different applications and characteristics, such as energy storage, filtering, and impedance matching.

Why do we use inductors over capacitors?

We opt for inductors over capacitors because inductors hold energy within a field whereas capacitors store energy in a field. Depending on the circuit's needs, like energy storage, filtering or impedance matching an inductor might be a choice, than a capacitor. What is the difference between resistor capacitor and inductor?
