I use plenty of the ESD safe automotive Q200 capacitors, close to a hundred per engine controller. I use Flexiterm on larger caps - 1206 and larger, usually automotive standard caps on 0603. Thermal cycling was most sensitive on BGAs and QFNs far before even the non-flex automotive qualified caps, I avoid those and try to stick with QFP and TSSOP.

This videos was very informative for me. Thank you and Ron for this great content.

[@derson754]

Love your channel Robert. I’m new in electronics and your questions make it so dang easy to learn the topic with the expert speakers

[@TomAHawk-py6vj]

Amazing that there is so much theory behind that and most of my circuits have caps chosen by a rule of thumb, price, availability, PCB footprint and work anyway :D

[@BJH-iv6nt]

Very informative and helpful. Thank you Ron and Robert.

[@shitpostaccount]

Wish I had access to this years ago. Had to learn this on the fly... Oh the pleasure when the EMS puts X5R instead of NP0 on your analog filters... days of searching for the issue

[@HL65536]

Thanks for reminding me of the DC bias problem. That was exactly the problem that turned out to be causing the problems I was having right now. I was using a 100V X7R 1µF to enable communication between 2 controllers that are 48V apart. Turns out, at 50V, the capacitance decreased by 75%, causing the voltage levels to get outside of comm specs too quickly, losing connection mid transmission. Will use film caps now as too high capacitance at 0V would cause turn on issues.

Thumbs up for another great video, but I would have liked to hear more about piezoelectric effects of type 2 ceramic capacitors because this is an important noise source in many products that I am working on...

[@dougphillips5686]

Great video, great information!

[@gilbertsense7443]

Thank you for the lessons more strength to do more ❤

[@ederandradhe]

Great video!

[@Jerzy-wedrowiec]

Great video, thank you. But it would still be interesting to see the difference in ESL for different case sizes of common ceramic capacitors.

[@ariparanthaman]

Great Video💡

[@franzliszt3195]

very informative

[@87Spectr]

I love you, Robert!

[@biswajit681]

Great !! Robert could you make session power supply control loop design?

[@p_mouse8676]

One very important parameter as well, is the frequency vs max voltage parameter. This is very often overlooked an can be very important in switching applications or other AC applications (like audio or other data acquisition situations). Especially for film capacitors, this can be an issue.

[@christopherjackson2157]

Capacitors are so much more complicated than most people think. I would like to be better at determining the tolerances and requirements for a given design without doing a lot of trial and error testing

[@Rx7man]

Wow, learned so much.. and I'm only 5 minutes in!

[@AreYouRazed]

Thank you for this video! Is it possible to get a pdf copy the slides?

[@MrTamhan]

Professor!

[@PiezPiedPy]

Cheers :)

[@tchiwam]

The best supercap discharge rate I got is about 1uA. I am looking for better supercaps all the time.

[@blanchehermine]

It's NP0, not NPO ;-)

[@dougphillips5686]

To be clear, NP ZERO

[@RobertFeranec]

Learned something new again :D

[@LeandroSehnemHeck]

​@@RobertFeranecAnd then It would be wise to update the title, fixing it.

[@sc0or]

@@dougphillips5686 Depends on what it’s used to pronounce 0. Americans use “oh” for 0 with numbers. But they “have” to use “zero” when letters and numbers are mixed, but they don’t. As in many other cases they tend to short everything, and from “zeer-oh” only “oh” remains ;)

[@artsiomshchatsko2490]

Are slides of this presentation available anywhere?

[@salec7592]

Seems like this conductive epoxy should replace solder and then any electronic component would be better protected from cracking. I guess that could hurt repairability though.

[@Dazza_Doo]

Is this a part of your Fedevel Course?

[@biswajit681]

Hi Robert any idea when Min Zhang new course on SMPS EMI/EMC course is going to publish?

[@RobertFeranec]

I know Min is working on new a course, but I don't know when it will be published.

[@technoinfochanel]

Where i can find this presentation?

[@halidfiliz5755]

I was wondering the same thing.

[@cdeblog]

it's very difficult to watch such big videos. The ideal time is 30 minutes. 😊

[@Dazza_Doo]

Why? don't discourage long discussions. You can take a break every 30 minutes? Right? Do you know how HARD is it to schedule people for these Interview meetings?

[@Rx7man]

@@Dazza_Doo There's a pause button for a reason.. I don't mind longer videos

[@BradKwfc]

Watch in 1.5X, trust me, it will be more difficult to listen to but that will make you pay closer attention to it.
