Aluminum electrolytic capacitors (also known as Al-electrolytic capacitors) are divided into three categories according to their characteristics and application fields: axial lead-type aluminum electrolytic capacitors, snap-in aluminum electrolytic capacitors and screw-type aluminum electrolytic capacitors. Among them, the ALS81H471DB450 aluminum electrolytic capacitor belongs to the snap-in type.

The ALS81H471DB450 aluminum electrolytic capacitor mainly has the features of long life, small volume and high capacitance. It is widely used in high-frequency electronic products as the filtering element, especially in power supplies, ballasts, display dimmers, etc. Its operating temperature range is -55°C - +85°C.

The ALS81H471DB450 aluminum electrolytic capacitor is made of axially sealed aluminum shell. It is a non-polar capacitor. The case is the same size as the paper tube type conventional capacitor, which is one-tenth of the size of the usual electrolytic capacitor. It is mainly composed of three parts: an electrolytic paper, an electrolyte and anode and Cathode foil.

The working principle of the ALS81H471DB450 aluminum electrolytic capacitor is that when a voltage is applied, a positive charge moves towards the cathode and a negative charge moves towards the anode, and a current flows between the two surfaces. Under the action of an electric field, a thin layer of oxide film precipitates on the surface of the anode, and a protection layer is formed to increase the insulation and prevent leakage. At the same time, the old electrolyte solution is replaced by a new electrolyte solution to reduce the equivalent series resistance and increase the capacity.

In summary, the ALS81H471DB450 aluminum electrolytic capacitor is widely used in power supplies, ballasts, display dimmers, etc. as the filtering element due to its long life, small volume, and high capacitance. Its working principle is that a positive charge moves towards the cathode and a negative charge moves towards the anode under the action of electric field, and a thin layer of oxide film precipitates on the surface of the anode to form a protection layer.
