Aluminum electrolytic capacitors are solid electrolytic capacitors featuring a very low equivalent series resistance (ESR) with the ability to handle very high voltages, making them broadly useful across many industries. Aluminum electrolytic capacitors are also available in a range of ratings from miniature to very large can sizes. The term “electrolytic capacitor” is derived from the presence of an electrolyte in the capacitor, such as boric acid, which provides the “thickness” of the capacitor. The LLG2C272MELB45 is an example of an aluminum electrolytic capacitor. This article will discuss the application fields and working principle of the LLG2C272MELB45.
