Aluminum electrolytic capacitors, also known as aluminum electrolytic capacitors, are one of the most popular capacitors. Generally, the anode of this capacitor is an aluminum foil processed with an oxide film and the cathode is fine metal particles such as aluminum particles and semiconductor materials filled with an electrolyte. Among them, the MAL211826221E3 is an aluminum electrolytic capacitor whose capacitance is up to 2.2uf, its rated voltage is 35v and its rise time is 7ms.

The application field of this capacitor is mainly for power supplies, inverters, switching power supplies, communication power supplies, UPS and other electronic circuit power, line frequency and high frequency rectification, filtering, bypass, coupling and other circuits, for audio frequency, intermediate frequency and high frequency circuit tuning.

The working principle of the MAL211826221E3 capacitor is to produce an electric field between the two plates of the capacitor. The electric field opposes the external electric field, so that the anode side C negative charge and the cathode side become C positive charge. When the power supply is connected, the electric field on both sides of the capacitor appears at the same time and produces the polarization effect. The electric potential on the two poles of the capacitor is different, forming a charge accumulation effect, and then the capacitance is formed.

The MAL211826221E3 capacitor is composed of two aluminum foils made of aluminum oxide. It is filled with an electrolyte and oxide particles to reduce its internal resistance. The electrolyte provides ions for charge storage, so that the capacitor has higher voltage and capacity, and the oxide particles effectively reduce the internal resistance. At the same time, the two aluminum foils are separated by two electrolyte layers to form a dielectric layer.

When applying to the circuit, the capacitor must be connected between positive and negative and two pins, one of which is the positive pin and the other is the negative pin. The most important thing is to pay attention to the polar direction when installing, otherwise, the inverse connection of the capacitor will easily lead to leakage of the capacitor, or even damage to the circuit.

In summary, the MAL211826221E3 aluminum electrolytic capacitors are widely used in power supplies, inverters, switching power supplies, communication power supplies, UPS and other electronic circuits, and its good performance makes it the most commonly used capacitors. Users should pay attention to its correct installation and positive and negative voltage when using.
