Anatomy of an AEC

To understand the features and working principle of the B41252C8338M002, it is important to get acquainted with the anatomy of an aluminum electrolytic capacitor. To this end, the following sections provide an insight into the assembly of the component, its electrical properties, and the working principle.

Assembly

The B41252C8338M002 consists of two main sections, the anode and the cathode. The anode is made up of a strip of aluminum foil and two additional layers of ionized separator material, typically cellulose or aluminum oxide, also known as Al2O3. This assembly is linked to the anode terminal with a metal rivet, mounted in the centre of the capacitor. The cathode section contains a lead-out wire (a single piece of metal), with a strip of electrolyte foils that link it to the cathode terminal.

Electrical Properties

AECs can offer various electrical properties that make them suitable for many applications. The B41252C8338M002, in particular, offers a maximum capacitance of 47μF, an ESR of 60mΩ, a rated Ripple Current Holding of 1.7A, and a rated working voltage of 250V.

Working Principle

The working principle of the B41252C8338M002, as well as many other AECs, is based on the movement of ions in an electrochemical cell. In the AEC, the current flows from the anode to the cathode, which provides a flow of electrons. The anode and cathode are separated by a layer of electrolyte, which contains positively and negatively charged ions. The anode and cathode are galvanically linked through the electrolyte, forming an electrochemical cell. When a voltage is applied to the capacitor, the ions move from the electrolyte through the anode and cathode, creating a capacitance between the two electrodes. This capacitance is measured in Farads, and indicates how much energy can be stored in the capacitor.
