Ferrite Inductor Calculator

Formula

To calculate the inductance (\(L\)):

\[ L = \frac{AL}{\left(\frac{100}{N}\right)^2} \]

Where:

\(L\) is the inductance (H)
\(AL\) is the AL value based on the inductance of the ferrite
\(N\) is the number of turns of the ferrite core

What is a Ferrite Inductor?

Ferrite inductors are a type of inductor known for strong electromagnetic properties. These inductors have a ferrite core that provides them with low electrical conductivity.

Example Calculation 1

Let's assume the following values:

AL Value (\(AL\)) = 5000
Number of Turns (\(N\)) = 10

Using the formula:

\[ L = \frac{5000}{\left(\frac{100}{10}\right)^2} = \frac{5000}{100} = 50 \text{ H} \]

The inductance is 50 H.

Example Calculation 2

Let's assume the following values:

AL Value (\(AL\)) = 3000
Number of Turns (\(N\)) = 20

Using the formula:

\[ L = \frac{3000}{\left(\frac{100}{20}\right)^2} = \frac{3000}{25} = 120 \text{ H} \]

The inductance is 120 H.
