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.
