Aluminum electrolytic capacitors are a type of capacitors which utilizes an electrolyte (liquid or solid) and a thin foil layer (anode and cathode) separated by a membrane (dielectric) to maintain a charge. According to the dielectric type, aluminum electrolytic capacitors can be divided into three types: polar, nonpolar and film capacitors. Polar capacitors are ideal for applications where the voltage, frequency and temperature are relatively low. Nonpolar capacitors are suitable for use in applications where the voltage and frequency of the circuit are higher. Film capacitors are designed for use in circuits that need to respond to the rapid variations of the alternating current.

The 420MXK180MEFC22X30 aluminum electrolytic capacitor has a maximum voltage of 420V, an equivalent series resistance of 175mΩ and a capacitance value of 180μF. Its capacitance-voltage (CV) characteristic is identified by its name. The “420MXK180MEFC22X30” represents its maximum voltage, equivalent series resistance, capacitance value, and voltage, respectively. Generally speaking, this aluminum electrolytic capacitor is ideal for applications that require high capacitance values and low equivalent series resistances.

In terms of application fields, aluminum electrolytic capacitors are widely used in power conditioning (e.g. voltage regulation, power factor correction), motor control, and signal conditioner circuits. Moreover, these capacitors are also used in audio-frequency circuits, television receivers, and radio circuits. In terms of working principle, aluminum electrolytic capacitors work by storing energy in a bound system of oppositely charged particles. The capacitance is determined by the amount of charge that the two metallic plates (anode and cathode) can exchange. When a capacitor is connected to a circuit, it can store electrical energy over a period of time which can be used to filter out noise or supply short surge energy when there is a sudden load.

The 420MXK180MEFC22X30 aluminum electrolytic capacitor is suitable for numerous applications including but not limited to power conditioning, motor control, signal conditioners, audio-frequency circuits, television receivers, and radio circuits. It features maximum voltage of 420V, equivalent series resistance of 175mΩ and capacitance of 180μF. It also has a CV characteristic which helps to determine the amount of charge that can be exchanged between two electrodes. This aluminum electrolytic capacitor is able to store electrical energy over a period of time, and also filters out noise or supply short surge energy when there is a sudden load.
