Aluminum Electrolytic Capacitors

Aluminum Electrolytic capacitors are widely used in a variety of applications. One of the most common aluminum electrolytic capacitors is 36D103G075CC2A. Its application fields and working principles will be discussed in this article.

Application Field

36D103G075CC2A aluminum electrolytic capacitors are typically used in power electronics, medical electronics, and PFC/ PWM circuit applications. With features of high temperature and humidity operating range, high ripple current, low ESR, low resistance, etc., the 36D103G075CC2A aluminum electrolytic capacitor is very suitable in these power electronic applications, which require large capacitance and high temperature operation, such as switch-mode, adjustable speed drives, active rectifier, etc.

Working Principle

The aluminum electrolytic capacitors are composed of three terminals which are two metal connections and one capacitor element. The capacitor element includes two aluminum plates and a liquid electrolyte between them. The electrolyte is composed of an electrolyte solution and a separator membrane. The separator membrane is made of a dielectric material that electrically isolates the opposite plates. The electrolyte solution determines the capacitance value of the capacitor. The electrolyte also provides the stability of the capacitance, a low resistance, and a reliable electrical bond between the plates. One of the aluminum plates is an anoded plate, while the other is a cathoded plate. The anode plate and the cathode plate vary according to the electrolyte solution and will affect the capacitance values.

During the operation of the 36D103G075CC2A aluminum electrolytic capacitors, the two plates build a charge on the surface of the metal plates. The polarized and charged surface can be sustained if the power is supplied to the capacitor plates. The charge is generated when the current passes through the electrolyte solution. During this process, the electrons flow into the anode plate and the current flows out of the cathode plate. The two plates act as an electrical charge storage device and charge will go in increasing capacitance values. The capacitor element of 36D103G075CC2A works effectively when a low frequency current passes through it. When the frequency is high, the electrolyte cannot provide sufficient charge to maintain the capacitance.

The 36D103G075CC2A aluminum electrolytic capacitor is an insulation-type capacitor with a large capacitance. It is mainly used in power electronic applications and can sustain high operating temperature and humidity, providing a reliable electric charge storage for power electronic devices. Its working principle is based on the electrolyte solution that is separated by two aluminum plates.
