Please come back, your videos are amazing.

"keep calm and use 100 nF"

ive been waiting like 5 years for afrotechmods to back on youtube

This channel is one of the best on YouTube, but sadly the owner is not posting anymore. Thank you for the excellent tutorials! (This channel is also proof that making money on YouTube is not about great content (like the stuff here), but rather opium to the masses, like the 5-Minute crafts and other crappy channels. ) Really sad... For what it is worth, Afrotechmods, you are sorely missed.

please come back with more fun tutorials, you're amazing person!

Another reason designers just use 100nF caps is because having more components on a pick and place machine is more complicated.
-
I Hope you’re okay there. 😊

I miss you Afrotech!

In power engineering this is a serious concern when designing capacitor banks since the capacitors tend be so large the inductance is far from negligible and if not accounted for your power factor correction will not be adequate. It is also important when calculating the proper size of your inductor for limiting in rush and out rush current.

I used to work at a place where one of the techs would refer to a cap leaking down its lead(s) as having a "poopie diaper".

Part of the reason for 100nF caps is the price and package sizes you can get them in. Since the ESL and ESR changes based on the package size and thus the frequencies that can be filtered. So for higher frequencies you want to use the smallest package you can, and it's easier and cheaper to get a 100nF cap in a smaller package than a 10uF or something higher. Tl; Dr size and capacitor type is more important for filtering than the capacitance.

No surprise here! Your video (as always) brought a smile to my face. I smile because you simply have absolutely no equal in your ability to convey a topic. How pleasant it is to watch tutorials that are devoid of mumbling or a drop in audio level when the tutor turns away from the mic. The students will appreciate not having to replay segments simply because of unintelligible dialog. You ARE the BEST! Chris - WA2ERQ

I just found this channel only to find out the guy left youtube. lol. Really liked his tutorials.
-
Here after 4 years, I'm still waiting for you to come back 😢

I love how you always explain how the ideal model taught in school is far from reality and point out the flaws in these models. Your videos are very down to Earth and realistic in their explanations while also keeping it simple enough that the average person such as myself can follow it, but without dumbing it down or omitting important technical information. Well done. This is a very difficult balance to reach.

I love this guy! He explains things so well. I've learned so much from him!

Hi there ATM, love your posts over the years ... the greatest gifts you can give to mankind are the ones that can never be repaid ... thanks for sharing your gifts with us ... you are a great teacher.

One thing I really appreciate, is that your enunciation is flawless. Being hearing impaired, I rely on captions a lot. Many times I start a video with no captions and the speaker just mumbles as though their mouth is stuffed with cotton. At that point, I just shut it off and go elsewhere. Having both good captions and a excellent speaker is quite a pleasant viewing experience for me. Thanks, and hope you return to making videos someday.
