The modern era of aluminum electrolytic capacitors
The first article in this series [1] covered the early history of electrolytic capacitors, from their invention around 1880 to the invention of the modern Al electrolytic capacitor structure in 1925. To summarize the early history, "valve metals" were recognized in the 1880s for their ability to conduct in one direction but impede current flow in the …
Capacitor
Capacitors are defined as electronic devices with two or more than two parallel arranged conductive plates in which energy is stored for long intervals and released when it is required over a time span in a controlled environment [13].These plates are separated by insulators suspended or dispersed in the electrolytic cell. These insulating materials include …
