how to select inductor for DC/DC conveters - Electronic Circuits Projects Diagrams Free

I am using mc34063 and I have used radial type and axial type inductor.
They have shapes of capacitor and 1W to 1/2watt resistors.
Some body told me that they are RF chokes.
They have values which i need.
But the CKT ouput falls when i connect load
Also one of the inductor which look like capacitor was burned out.
It might have saturated and then gone.

So Do i have to use some power toriod type of inductors.
Can anyone throw some light on this problem

Please don't post the same question more than once, the other thread has already answered your question! - you need a power inductor, usually wound on a toroid.

Thread locked!.
