Are the parameters of aluminum electrolytic capacitors affected by the application environment?

1 Temperature characteristics of capacitance 🍏Are the parameters of aluminum electrolytic capacitors affected by the application environment?Capacitance varies with temperature. The change itself is determined by the rated voltage and capacitor size, from 25°C to the high temperature limit, the capacitance increase is generally not more than 10%. For the lowest rated temperature of -40℃, the [...]

Introduction of electrolytic capacitors

1.1 Overview 😋Electrolytic capacitors should be called electrolytic capacitors because one of the electrical stages of such capacitors is not a metal but an electrolyte or metal oxide. In short, the conductive carriers of this electrode are no longer electrons but ions. This is the basic characteristic of electrolytic capacitors. Now. According to the characteristics of [...]
