Thanks for this excellent video shining a light on the humble capacitor. For me it really exposes the need and what parameters to look at when selecting the right capacitor for the job. Maybe also helps explain the subjective differences in 'sound' of capacitors used in audio 👍🏼
Thank you for this video. Your English is very understandable and easy to listen to. One note: the word impedance has the accent on the second syllable (the 'pe') in English. The video is placing the emphasis on the first syllable (the 'im') which made the pronunciation hard to understand for this word. I look forward to viewing more of your videos.
Guess it has to do with the way this word is pronounced in Romanian, the accents are different than in English. I will try to keep in mind the correct pronunciation next time.
I didn't use any special plugin, it was just the Murata website; They offer this feature for most capacitors, just go over the graph with the mouse and the cursor will appear.
Hey, I have been watching your videos for a long time. Your work is legit and far more precise than other youtube channels. I am very thankful for your videos. Talking about precision and accuracy, can you tell me how to accurately model the capacitance value that represents the coupling between a DUT (Device under test) and the ground plane when carrying Conducted Emissions Test for compliance. I really need a legit answer and I was hoping if could help me with that? Thank you once again.
Hello thanks for the video, How do you estimate this inductance if they don't dive it in the datasheet? what is the magnitude of the inductance in general?
The best way would be to measure it somehow - using an LCR meter or something similar; as long as the coil has an air core, you could use an online calculator and just plug in the dimensions and number of turns to get an approximate value; but if the coil has a magnetic core of unknown proprieties, then estimations are very difficult.
If the "c" is a constant, you can use a behavioral current source, and express its value based on a node voltage (ex: I=0.04*100e-6*v(n001)) 100e-6=100nF and n001 is the node with the applied voltage)
Excellent video, but how you would change with time (maybe using if) the resistance as you did with capacitance. I have tried to do that but my tries were in vain. Help of LTspice is helpless.
Hello Mr. Remmoz! You can try to place in the field of value of the resistor something like: R=formula for example "R=1+time" without brackets or anything else. Let me know if this works for your needs.
Can you give me a few more details about what exactly you are trying to simulate? What type of simulation you are performing and what are you trying to achieve with the value change. If you want, we can move this discussion to email, so we can discuss on the actual simulation. My email is feszelectronics@gmail.com
Hi from France ! I really enjoy the content of your videos BUT your voice's tone (is it because of the microphone you've build?) make it impossible for me to watch them more than a few minutes. Too much high medium frequencies and a lot of distorsion and noise as if you were speaking in a long pipe. Am I the only one to complain about ? (Please note that many other YT english speaking channels I'm interested in have a very good sound quality, and I have no hearing problems whatsoever, ). Thanks if you could fix that issue. Best Regards
Hello YvesLesage, I am not sure why you are having this problem... If you want to help me with this, we could continue this discussion by email (mine is: feszelectronics@gmail.com). I could send you a bit of audio from this particular video, to see if my recording is bad, or if its some youtube setting.

You are the best about Ltspice. Thanks for videos
Yes, indeed!
I'm happy you enjoy the content! I hope my future work will be to your liking also.
Your LTspice videos are amazing man. I learned a lot just watching a few clips. You deserve more subs!
Fantastic video. Excellently explained and so many nuggets of in on Ltspice whilst covering and essential topic of non-ideal components
You are doing great work with ltspice.
Thanks for the videos👍
I'm really glad you liked it! I hope you will enjoy future videos also

I'm loving the details. Thanks for the good work.
Excellent video!
Keep up with the good work, thanks for sharing.
Great video. Well done! very informative and comprehensive.
I'm happy you enjoyed it! Thank you!
you are a monster..!! really great video..!! you earned a subscriber..!!

Fantastic, thank you

Thank you so much for the great video! Could you share which web plugin you use to read graphs?

@@FesZElectronics THANKS
Thank you for such excellent content. Question: how would one best model voltage-dependent leakage (ie 0.04 x C x applied V)? Thanks
If the "c" is a constant, you can use a behavioral current source, and express its value based on a node voltage (ex: I=0.04*100e-6*v(n001)) 100e-6=100nF and n001 is the node with the applied voltage)
Can you simulate voltage coefficient of any ceramic capacitor
Excellent video, but how you would change with time (maybe using if) the resistance as you did with capacitance. I have tried to do that but my tries were in vain. Help of LTspice is helpless.

@@FesZElectronics Unfortunately it is not working. But, may be, Im doing this in wrong way. time in not resolved.
