For example, for the usual 1400PF capacitor, the actual capacity of Japan TDK is 1600PF, which is to compensate for the capacity deviation caused by attenuation. Capacity decay is a normal phenomenon, as long as it is a capacitor, this problem exists.
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 …
Calculating the Lifespan of Electrolytic Capacitors with De-Rating
In the early 2000s, aluminum electrolytic capacitors (Al e-caps) were failing at a far higher rate than expected, a phenomenon commonly and dramatically known as the capacitor plague. The cause was tracked down to an interesting story of industrial espionage where a formula for the electrolytic solution of the capacitors was stolen, but …
