Aluminum Electrolytic Capacitors

An Aluminum Electrolytic Capacitor (ELC) is a robust and reliable electrical component used to store and distribute electric charges in a circuit. An ELC is a type of capacitor with a very high electrical capacity due to its unusually electrolyte-soaked electrodes. This type of capacitor is often used in electronic devices such as radios, television sets and other electronic equipment such as computers, home entertainment systems and industrial purposes. The basic function of an ELC is to provide a surge of energy when there is an increase in voltage or current in the circuit.

The LGY1H392MELA30 is an example of a aluminum electrolytic capacitor. It is a one board package with radial lead construction. It has a low impedance and high capacity that make it suitable for use in applications such as DC to DC converters, motors, power supplies, personal computers and home audio equipment. This aluminum electrolytic capacitor has an operating temperature range of -40°C to +105°C and has an ambient humidity range of 0% to 45%.

The working principle of an Aluminum Electrolytic Capacitor is based on Faraday’s Law of Electrolysis. According to Faraday’s Law, when an electrolyte solution is exposed to a current, an electric field sets up within it and separates the charged molecules. This creates a separation of negative and positive ions, which then move through the liquid electrolyte to the cathode and anode, respectively. In an ELC, the aluminum oxide deposit on the anode acts as an insulating layer, while the electrolyte liquid provides the medium for charge mobility.

The capacitance of an ELC depends on the relationship between the distance between its anode and cathode plates and the thickness of the aluminum oxide deposit that lies between them. The capacitance of the ELC increases with increasing plate spacing, but it simultaneously decreases with increasing aluminum oxide thickness. This relationship is known as the “capacitance-dependence on gap-thickness”, and it is the main factor that determines the capacitance of the ELC.

The LGY1H392MELA30 Aluminum Electrolytic Capacitor has a capacitance of 390uF and is suitable for use in various application fields such as power supply, inverter, audio and input standby application. It is particularly suitable for power supply, inverter and audio applications, as it offers low ESR on ripple current and long life time. This type of ELC is often used for managing power surges in a circuit, such as a motor or audio systems. As such, it is essential to maintain the proper level of capacitance in any type of circuit in order to ensure maximum efficiency and performance.
