Aluminum electrolytic capacitors are an important member of the capacitor family, which are mainly used for combined filtering, signal output and other applications in the circuit. As one of the most typical aluminum electrolytic capacitors, 400AX24MEFC12.5X16 is widely used in many fields. This article will introduce the application field and working principle of aluminum electrolytic capacitors.

Aluminum electrolytic capacitors are widely used in power supplies and switching power supplies, audio frequency circuits, high frequency circuits, and telecommunications. Specifically, it can be used in switching power, linear power supply, PFC filter, and EMI filter, which need large capacitance and isolating ability. Its good ripple absorption and long life span makes it an ideal choice for various application fields. In addition, it can also be used in consumer electronics, automotive electronics, etc.

Aluminum electrolytic capacitor is an elecrolytic capacitor that uses a liquid electrolyte anode to form a double layer of oxide film on the anode. It uses electrolyte instead of air to connect and increase the capacitance. Compared with other normal capacitors, it has higher capacitance value and can be used in high frequency circuits. So, its application is extensive. The 400AX24MEFC12.5X16 is constructed with a formed aluminum strip and surrounded by a metallic sheath. The capacitive element is sealed by a vinyl sleeve with an insulating paper inside. The operating temperature of this aluminum electrolytic capacitor ranges from -40 to +105 degrees celsius.

Here is an introduction to the working principle of aluminum electrolytic capacitors. As mention above, it is composed by a formed aluminum strip and surrounded by a metallic sheath. When the electric current flows, the aluminum strip is used as the anode of the capacitor. The oxide film coating the aluminum strip acts as the separator and part of the capacitor dielectric. The electrolyte acts as the cathode. When the current flows through the capacitor, the polarity of the terminals changes from positive to negative. This can cause a semiconductor effect in the metal surface, which helps to control the current flow in the capacitor and provides stronger insulation in the circuit.

In conclusion, 400AX24MEFC12.5X16 is an aluminum electrolytic capacitor with high capacitance, good ripple absorption and long life span. It is used in many application fields, including switching power, linear power supply, PFC filter, EMI filter, consumer electronics and automotive electronics. Its working principle is shaped by the aluminum strip with oxide film as the anode and electrolyte as the cathode. All in all, it is a very versatile aluminum electrolytic capacitor used in many application fields.
