Aluminum electrolytic capacitors are common electronic components. They are polar capacitors with wide application fields. 350MXC470MEFC30X45, which is widely used in computers and consumer electronics, is an aluminum electrolytic capacitor. This article firstly talks about its application field, and then the working principle.

The application fields of 350MXC470MEFC30X45, as one of aluminum electrolytic capacitors, include the power supplies of computers, large and small electronic devices. It can be also used in TVs, VCDs and other consumer products. Almost all LED street lamps, solar lights and small electronic devices include 350MXC470MEFC30X45 and other aluminum electrolytic capacitors.

In the aluminum electrolytic capacitors the working principle is based on the electrolytic separation. Nut whose outer cover made of combined aluminum oxide film, serves as the positive electrode. Aluminum whose surface in the inner is processed as oxide film serves as the negative electrode. Pure water, alcohol or other electrolyte serve as the bridge of two electrodes. Working voltage is 0.35V, capacitance is 470μF, and high rate voltage is 30V. The value of 45 is equivalent to the length of specifications in millimeter.

In an aluminum electrolytic capacitor, when a current flows through the electrolyte, oxygen ions carried by the electrolyte flow to the anode, forming oxide film and releasing electrons.Meanwhile, water molecules in electrolyte break up and hydrogen ion enter the cathode. Through such process, two electrodes form a nonlinear distribution of electric charge, and hence form an electric field.

When charging the aluminum electrolytic capacitor, electrons flow from the cathode to the anode, and the capacitance is increased. When the electric current is interrupted, the electrons move to the anode and form a capacitor together. The charge and discharge process of aluminum electrolytic capacitors depend on the flow of electrons.

The capacitance of aluminum electrolytic capacitors would decrease a lot for a long time use. The use of 350MXC470MEFC capacitors requires change in process control and circuit parameters to reduce the influence and loss caused by dielectric loss. This means good factors such as using lower voltage, slower charging and discharging speed, and also paying attention to the use of capacitors in terms of temperature, humidity, operation mode.

In order to get reliable performance of the aluminum electrolytic capacitors, circuit design should consider the temperature, DF, life expectancy and form of aluminum electrolytic capacitors, etc., arrangement and layout shall be done the make the area small in order to avoid the influence of interference, and try to limit the applied voltage in the range of the maximum rated voltage. The capacitor fail will cause some interference, so the circuit design should pay more attention to the risk assessment and safety design.

The 350MXC470MEFC30X45 aluminum electrolytic capacitor is a widely used component in the electronic world. It carries out its function in electronic circuites through its application fields and working principle. It\'s important for the device engineers to pay attention to the use of the capacitors, in order to ensure the reliable performance of the device.
