Hello everyone,

I'd like to find out if it is practical to build a boost converter using axial lead inductors. The input voltage would be 5 volts and the output 12 volts at 1 amp (switching freq is 500khz). The reason I ask is because, first, I'm totally new to using inductors (this is my first project involving one), and second, axial lead inductor's values are relatively easy to figure out (from their colour bands) as compared to winding one or taking unlabelled ones off of old PCBs.

May I also know what factors determine the maximum current that can be passed through one without significant I^2R losses (from calculations, I came up with a peak current of 3.2 amps through the inductor). Is it the wire size, or are there other factors in play that I should consider. At what frequency would I have to start worrying about the skin effect. Also, at what flux density (B) do 'E' shaped ferrite inductor cores start to saturate.

Appreciate all input.
