00:00:00.089 hello my difference of electronics today 00:00:02.96000:00:02.970 I will talk in this video about super 00:00:04.94000:00:04.950 caps and standard electrolytic caps for 00:00:08.24000:00:08.250 this reason I invite Frank 00:00:09.68000:00:09.690 Frank's hello hello his pragmatic are 00:00:12.29000:00:12.300 for super caps and well we have this 00:00:15.37900:00:15.389 kind of super caps Frank which is in the 00:00:17.59900:00:17.609 same package 00:00:18.76900:00:18.779 very very cool same package it doesn't 00:00:21.01900:00:21.029 look something else just will be 00:00:22.60900:00:22.619 different colors from from here this is 00:00:25.87000:00:25.880 typing but here I have one milli farad 00:00:30.41000:00:30.420 and in the same package 54 at so a lot 00:00:36.11000:00:36.120 big difference and how is this possible 00:00:39.02000:00:39.030 to do to build it ok I explain it 00:00:41.75000:00:41.760 of course as you see here in the 00:00:44.45000:00:44.460 cross-section the inner construction is 00:00:47.06000:00:47.070 is the same so it's a won't tie up with 00:00:49.36900:00:49.379 electrode surface like a loom medium 00:00:51.20000:00:51.210 foil you wrap it and that's the same 00:00:53.02900:00:53.039 construction but real different is the 00:00:55.67000:00:55.680 electrolytic what we are using 00:00:57.36900:00:57.379 electrolyte there's use of special 00:01:00.79900:01:00.809 electrolyte it has a decomposition 00:01:03.20000:01:03.210 voltage it's called it's around 2 up to 00:01:05.17900:01:05.189 3 volt and this limits the the rated 00:01:09.85900:01:09.869 voltage and the secret behind is the 00:01:12.89000:01:12.900 active carbon which is inside this this 00:01:15.98000:01:15.990 product it leads to an really low ESR 00:01:18.98000:01:18.990 and this means that I can discharge for 00:01:22.76000:01:22.770 example 50 50 for our type with up to 90 00:01:25.34000:01:25.350 MS o so this is really high and in fact 00:01:28.28000:01:28.290 what you have to handle it and this is 00:01:30.44000:01:30.450 the real you noticed the secret behind 00:01:33.08000:01:33.090 so I have a very very low ESR and that 00:01:35.78000:01:35.790 that can put a lot of energy in very 00:01:37.96900:01:37.979 short time how about the compression 00:01:40.55000:01:40.560 with the battery about the energy 00:01:42.14000:01:42.150 density it is this is really different 00:01:44.60000:01:44.610 the energy density is really low 00:01:46.31000:01:46.320 compared to a battery but power density 00:01:49.76000:01:49.770 is really really high so I can this 00:01:51.49900:01:51.509 means I can charge it really fast and 00:01:53.35900:01:53.369 discharge it really fast but when I want 00:01:55.58000:01:55.590 to replace a battery it's maybe not a 00:01:58.60900:01:58.619 good choice because energy density is 00:02:01.58000:02:01.590 not so so high as a battery thank you so 00:02:05.27000:02:05.280 much and the address can remark that 00:02:07.78900:02:07.799 Frank have a nice webinar which you can 00:02:10.19000:02:10.200 click on this link below 00:02:13.05000:02:13.060 we have also a demo set up in my next 00:02:15.72000:02:15.730 video and just watch it see you next 00:02:18.51000:02:18.520 time
