Inductor design help

[hexaguy1100]

I need an inductor rated 100uH,1.5Amps. How can I design one myself? I have some toroid ferrite cores with me (10mm dia x 5mm). Can I use these to make the required inductor? Please help.

First, please advise your application, PFC inductor or storage energy inductor or filter inductor, SMD configuration or pin through? then design the inductor.

It is for a buck converter.

First you need to find out that the core you have can sustain require power and current. use this tool to find out what ferrite you have got, by cross checking its dimensions n color

once verified, enter the required inductance it will tell you number of turns required!!!
