Quick question about inductor placement

[Raptor550]

OK, does this look more or less right? do you think my inductors are far enough away? Any blaring mistakes? If not I'm gonna put em in.



Also, with inductors is it bad to have the two ends of the inductor touching? Thats how they were when I bought them and I didn't know if I should keep them like that for some reason, should I make it so the ends are separated?

The tinned ends of the inductors must definitely not be touching. I would move the ends further apart so they don't inadvertently come in contact.

You will want to separate the two ends (wires) on the inductor, since if they're touching, you'd be shorting out the inductor, making it ineffective. That is, if the bare parts are touching like they seem to be in your 2nd pic. The insulated parts can touch, but if you can separate them, it'll be better in the long term.

YEY! thanks guys!

Go look at the guide here to placement of inductors in relation to each other.

As far as placement goes, this actually doesn't look bad. I'm glad you understand now about why the leads of the inductor (or a capacitor, or any component for that matter) should not be touching.

I think they're shipped like that just for neatness.

Separate the leads, that's just a way of packing them neatly. Otherwise everything looks fine, people worry about inductor placement way more than they need to. I've spent the last two weeks trying to make air core transformers and even trying to get two inductors, one wound around the other, to have a decent coupling coefficient is very difficult.

Thanks for the advice, I have got a page to show my project now:
