Yes. A small inductor and a large transistor together feels a little odd, but at least at input a small SMD part should do. Then there are lead inductances. Everything has some. Logged coppercone2 Super Contributor Posts: 11181 Country: $ Re: How to make small inductors like 10-20nH...
If the inductor is installed in the circuit as shown, its role will be completely different. The light bulb is a resistor (resistance generates heat and causes the filament in the light bulb to shine). The resistance of the wire in the coil is much lower (it is just a wire), so ...
There is a small R2 inductor on backplate side of PCB and I tried putting my finger on it to see if noise was coming from it and it improved and nope. Even tried covering up the MLCC behind the GPU and no difference. Buzz/whine most coming form front of PCB I think. ...
It's likely more a problem of the levels of QC/research/manufacturing complexity needed to eliminate whine. It could probably be solved if inductor manufacturers did extensive research on a potting material that eliminated vibrations between the coil and casing, if they did extensive QC...
1) In Line Noise filters where the inductor must support large AC voltages without saturation. 2) Switching Regulators Inductors to handle large amount of DC bias current 3) Pulse Transformers and Flyback Transformers as its residual flux density is near to zero gauss. With the saturation flux ...
You can make the capacitor C variable, in case you want the Hartley circuit to work like a variable frequency oscillator. Remember that the indicated tapping on the coil L doesn't need to be at exactly at the middle of the winding, which means for example, the circuit may run without an...
We'll lump these together, since they (mostly) all make use of coils in some way.Transformers(not themore-than-meets-the-eyekind) usually involve two coils, butted up against each other, with a couple lines separating them: Relaysusually pair a coil with a switch: ...
How to Make a Softstarter: In this small project we will be having a closer look at appliances that require a softstarter in order to properly work with a limited output current system. The shown appliances in this project include an inverter, a boost co
How to Build a Spark Gap Tesla Coil (SGTC): Shoot foot-long bolts of lighting through the air, light fluorescent tubes without wires, and power your other high voltage experiments with the aid of this tabletop-sized Tesla coil! Once the parts have arri
An analog to an inductor is a mass of water flowing in a river. It isn't possible to cut a section out of a river and still have that removed water continue to flow. The superconducting analog is freezing water being directed in a circle to make a flywheel from the ice. Upvote 0 ...
