Hi guys, I am doing a research on the capacitor industry and would like to ask some question. I did some basic research online that find out that aluminum capacitors are mainly used in the following areas. Power supply output filter Blocking and dc-bypass circuits Motor start and other non-polarized capacitors Audio applications Energy discharge capacitors Photoflash Strobe Applications However, I have no clue that products are included in which area. For instance, that products need aluminum capacitors for "power supply output filter"? Can someone please give me a few examples in each of the seven areas mentioned above? Many thanks in advance!!!
