MAL215252689E3

Aluminum electrolytic capacitor (hereinafter referred to as "electrolytic capacitor") is a widely used practical device in electronic circuit.The product has small volume, large capacity, good self-healing ability and low cost.At the same time, it also has its own disadvantages, such as poor temperature and voltage resistance, and poor tolerance of ripple current. So it can be widely used in a variety of electronic products.

The MAL215252689E3 aluminum electrolytic capacitor is a 20V aluminum electrolytic capacitor produced by Nichicon Corporation in Japan. Its capacity ranges from 820μF to 1020μF, and its tolerance is ±20%.It has high reliability, long life expectancy and excellent temperature and voltage characteristics that make it suitable for use in high-load inverter and DC-DC converter circuits.

The working principle of MAL215252689E3 aluminum electrolytic capacitor is based on the principle of electrochemical reaction. The capacitor consists of a pair of anode and cathode electrodes separated by an electrolyte. The electrolyte acts as an insulator and also acts as a medium for the transfer of ions. When a voltage is applied across the terminals, an electric current is formed between the anode and the cathode, and the flow of electrons produces an electrical charge, which is stored in the capacitor.

Due to the non-linear permeability of electrolyte, the effect of leakage current will increase more and more with the increase of long-term continuous current, it is not suitable for the application of line-to-line DC and AC. In addition, since the structure design of electrolytic capacitor is relatively simple and easy to produce, it has high production efficiency, but the self-healing ability is poor, so it cannot be used for high-frequency circuits.

Generally, MAL215252689E3 aluminum electrolytic capacitors are usually used in audio frequency converter, DC power circuit, LCD color television circuit, telecommunications power supply and other electronic circuits. The transmitted signal frequency is usually around 20KHz to 20KHz. Its load capacity is high and the cost is low.

In summary, the MAL215252689E3 aluminum electrolytic capacitor has the advantages of small size, low cost and high load capacity. Its application range is relatively wide. However, due to the drawbacks of its working principle, it is necessary to pay attention to the selection of current capacity when selecting them.Strong adjustments of the positive temperature coefficient (PTC) can also help the capacitor to perform better in high current and high frequency applications.
