As for inductor, you can use tantalum ot electrolitic capacitor paralled ti ceramics; Also you can use ceramic capacitor with resistor to create controlled esr (snubber) for desired frequency responce. Low-ESR ceramics can lead to rather large and destructive spikes, remember it! Also ESR-controlled capacitors exist, but its rather expensive.
no no no, the HF energy will not be dissipated as heat! The ferrite bead has a high impedance at high frequencies, which means that they behave more like an open switch, not letting the high frequency signal pass. An open switch does not dissipate any energy either, it just isolates one side of the circuit from the other.
You seem to be mistaken on what a ferrite bead is as compared to an inductor is! What you said is true of an inductor, not a ferrite. A ferrite is an inductor with a low quality factor, Q. As you can see from the ZRX chart, what you said is valid for the the inductive zone, but not for the resistive zone. In the resistive zone, the impedance of the bead is primarily from resistance, NOT inductance. So it is indeed dissipated as heat. www.analog.com/media/en/technical-documentation/application-notes/an-1368.pdf
@@uwezimmermann5427 One of the most important traits in engineering is the ability to make a mistake and learn from it. Niels Bohr said “An expert is a person who has made all the mistakes that can be made in a very narrow field.” It's also important to learn from the mistakes of others, so thank you Uwe and Kyle for your comments here.
This is great stuff! Extraordinarily good job of explaining the basic concept and usage in just 1 min! Thank you!
This is great.
I would like to see a link in the description for those who want to learn more.
Good job, as always !
Glad to hear that you enjoyed! Check out this app note www.analog.com/media/en/technical-documentation/application-notes/an-1368.pdf
@@MicroTypeEngineering Interesting. Thanks for sharing!

I have one that smoked and lifted from one end, can I replace it with a new one so that the audio amplifier circuit works as normal
"It will filter it as heat"
Yeah, that's how it happened
question .. do they show continuity on a DMM in circuit
Wonderful !
Excellent content as always!
These are awesome! You're a legend!
man love this video. make it a seriess!!
How to measure a smd in a pcb
Good info
did u mean low esr cap?
Nice, appreciate the gotcha part
Excellent
Good stuff. 👍
Thicker wire, shorter wires and ferrite beads.
Great job.
