00:00:00.370 00:00:00.380 whether it's industrial or automotive
00:00:03.290 00:00:03.300 applications aluminum electrolytic
00:00:05.210 00:00:05.220 capacitors are ideal for DC lengths and
00:00:07.820 00:00:07.830 bulk energy storage functions learn what
00:00:10.850 00:00:10.860 is inside these cans and how Kemet
00:00:14.410 00:00:14.420 manufactures them construction starts
00:00:17.359 00:00:17.369 with edged and formed aluminum foil as
00:00:19.580 00:00:19.590 an anode the etched foil provides up to
00:00:23.060 00:00:23.070 a hundred times more surface areas in
00:00:24.950 00:00:24.960 rock oil this increase means more
00:00:27.859 00:00:27.869 surface area to grow the aluminum oxide
00:00:30.040 00:00:30.050 which is the dielectric layer the
00:00:32.720 00:00:32.730 cathode layer also uses aluminum foil we
00:00:36.410 00:00:36.420 create a winding with the anodized an
00:00:38.630 00:00:38.640 old foil and cathode foil separated by a
00:00:41.389 00:00:41.399 paper layer as the foils are whelmed
00:00:43.819 00:00:43.829 connection tabs are welded into place
00:00:45.680 00:00:45.690 and then connected to the underside of a
00:00:48.290 00:00:48.300 terminal deck through the paper
00:00:51.260 00:00:51.270 separators the conductive electrolyte
00:00:53.720 00:00:53.730 electrically connect the cathode
00:00:55.760 00:00:55.770 terminal to the counter electrode the
00:00:57.889 00:00:57.899 electrolyte is selected based on the
00:00:59.900 00:00:59.910 finished capacitors design rated voltage
00:01:02.569 00:01:02.579 rated temperature ESR and operational
00:01:06.109 00:01:06.119 lifetime determines which formulation is
00:01:08.539 00:01:08.549 you quality is continuously monitored
00:01:11.570 00:01:11.580 throughout the manufacturing process the
00:01:14.030 00:01:14.040 wild element is inserted in the can and
00:01:16.969 00:01:16.979 the deck lid is sealed each capacitor
00:01:19.870 00:01:19.880 undergoes an aging process at
00:01:22.249 00:01:22.259 accelerated temperatures to repair any
00:01:24.830 00:01:24.840 dielectric clothes introduced during
00:01:27.020 00:01:27.030 construction the capacitors electrical
00:01:30.200 00:01:30.210 parameters are monitored during the
00:01:32.240 00:01:32.250 aging process afterwards each capacitors
00:01:34.850 00:01:34.860 capacitance impedance ESR and leakage
00:01:38.480 00:01:38.490 current are verified after construction
00:01:41.080 00:01:41.090 aging electrical tests and final
00:01:44.179 00:01:44.189 assembly finished aluminum electrolytic
00:01:46.730 00:01:46.740 capacitors are packaged and ready to be
00:01:49.160 00:01:49.170 shipped for more information about
