There are also other types of fixed value resistors but the above are the ones most likely to be found in people’s resistor drawers. Are there any types that you find specially useful for some application? If so, please share with us in the comments below, along with any other types you frequently use. And if you want another run down on typical components you might find or want for your collection, consider checking out our article on capacitors.

I have several xxx-in-1 kits that I purchased (used) over the years. But my daughter showed no interest in them… (sigh!)

Wingate related that he decided to start out by purchasing a commercial kit for constructing a solid-state coil.

Yes, that rubberization normally does no good. On the electric toothbrush it starts to get sticky, on a small (cheap) nose hair cutter it got so sticky, you could not put the thing down any more OK, you could say: throw away a $3 gadget after some years, but why should it be like that? I covered it in talcum powder

“They already had T-coil magic that worked for vacuum tubes, but found that transistors were different enough to require new incantations. They had no proper equations for how to design T-coils for bipolar transistors, because the derivation is really, really hard. The input resistance complicates things enormously. Bob says, ‘Ya know, I think I know how to do that.’ He spent the better part of a year trying to figure it out. He says this is the hardest derivation he’s ever done in his entire career. But he figured it out.

A lot of small single-cell motor controllers use SO-8 MOSFETS from Alpha/Omega semiconductors. Something like AO4402 (5.5mOhm RdsOn@2.5VGS), SI7858(3.5mOhm RdsOn@2.0VGS).

The 200-in-1 kit is still available new… https://www.amazon.com/Maxitronix-200-in-One-Electronic-Project-Lab/dp/B0002AHR04

Wingate also shopped around for the specialized energy-storing capacitors that are part of his design.

Another aspect of that technology is the high reproducibility which allows the end-user to swap inductors with no or limited setting. That brings a clear gain in time.

Of course you can change some stuff in that program and see what happens—go ahead, you won't permanently break anything.

Typical applications for thin film are wherever high precision is required. Thick film has application in pretty much any electrical device — some PCs contain over 1000 thick film SMD resistors.
