Aluminum electrolytic capacitors are pivotal components in today’s electronic equipment, and their working principles will be discussed in this article, together with the application field of LGU2P391MELZ.

Capacitors are two-terminal electrical components, used as essential components in all kinds of electronic circuits. It can store electrical energy temporarily in electric field, or filter signal and adjust electric potential. In general, a capacitor consists of two metallic electrodes, making contact with an electrically isolating medium called dielectric, while LGU2P391MELZ belongs to aluminum electrolytic capacitor, it has aluminum foil as anode and oxide layer as dielectric.

When the capacitor is put into use, the power supply source will provide voltage for the capacitor. At the same time, because of the physical reaction of ions’ migration between aluminum and liquid, the oxidation-reduction reaction will produce a powerful electric current, which will form and accumulate positively charged ions on the surface of oxidized aluminum foil. This process can continue only when the voltage applied to capacitor guarantees the reaction. In the condition of same voltage, electric current of a bigger capacitor will be bigger, indicating the relation between electric capacity and electric current.

LGU2P391MELZ is designed with a radial-leaded aluminum electrolytic capacitor. It is suitable for high-frequency applications and delivers a high capacitance of 390μF and voltage of 25 V. Its capacitance tolerance is ±20%, it also features self healing properties, ensuring safe use. The self healing property of LGU2P391MELZ, combined with it\'s high capacitance density, makes it ideal for use in power supplies and other circuitry.

LGU2P391MELZ, as an aluminum electrolytic capacitor, it is widely used in the field of automated systems, power electronics, motor drives, automotive and industrial controllers. Besides, it is applicable for power supplies, audio amplifiers, counters, timers and various kinds of computer related equipment.
