Inductor Core Al Value

Enter the actual number of turns of wire and the measured inductance value making sure to enter the units correctly as nhuh or mh click on the calculate button and the calculator will give you the derived al value of the core. If you need to calculate the al value of a core and you know the number of turns and the inductance across a winding.

The unit of inductance is the henry.

Inductor core al value. L n2squared x al where l is the inductance in henries and n is the number of turns. Density of this material and better dc bias performance allows selection of a core with higher permeability and higher al value reducing the turns count and copper losses. Again core losses are small due to the relatively small ac flux in the.

Stan zurek al value. Most commercially available cores have published al values. By filling in two of the known values the third value will be calculated.

Calculatoralvaluefrominductanceandnumberofturns calculator of al value from inductance and number of turns if inductance and number of turns are known the a l value can be calculated as. This calculator will find the desired missing value for number of turns al value and inductance. Inductor cores with higher al values tend to saturate more readily than cores with lower al values.

The formula for inductance is. The a l value is especially useful when designing with gapped cores for instance for gapped inductors or flyback transformers. So the a l value for a given core can be calculated if the number of turns is known and the inductance can be measured.
