Inductance or Inductance Factor (Al) value of ferrite core transformer?

[ambi]

Could any one pl tell me that what can be the inductance or Al value of ferrite core transformer of the below attached circuit?

Thanks:smile::smile:

Where did you copy this from?

I guess it´s a typo, and he´s referring to the parameter inductance factor AL instead AI.


Or just a lower case L ...ts

Knowing the frequency will make it easier to guess the AL. You wont be very wrong if you get similar size core that is made for power transformers, most materials are about the same.

Au contaire, @vbase each supplier has at least a dozen types out of a thousand different mixes of ferrite.

for example TDK have hundreds from which dozens are most popular, like N87 or N30 or T65 or ...

There are hundreds on offer by manufacturers but off the shelf the choice is limited to one or two.

Your perception is only limited by your experience.

Here are 87 stock types of cores with 22 different effective gap sizes
In torroids alone...

HII @SunnySkyguy .. i got this circuit by googling..
@ Vbase am sry i don't frequency value but is there any other possibilities? :sad:

I figured that much but it looks like it is from an Italian ferrite company which should have a complete BOM and layout.
