Aluminum electrolytic capacitors are mainly used in AC and pulsed circuits, and by far, they are the most widely used type of capacitor. They offer a combination of high capacitance capacity, with low cost and a large range of temperature and voltage ratings. They are typically made with a sheet of aluminum foil that is rolled up in a coil and then dipped in an acid solution to form an electrolytic layer that acts as an insulator. SEK010M200ST capacitors are a type of aluminum electrolytic capacitors, which are also known as wet or canned capacitors.

SEK010M200ST capacitors have a wide range of applications, such as audio power supplies, transistor power amplifiers, power inverters, RF transmitters, transformers, contactors, and spark plugs. They have good temperature and voltage stability, and their long life makes them a suitable choice for long-term use in high load applications. Additionally, they are often used in coupling, smoothing, and decoupling circuits due to their ability to absorb high frequency transients.

SEK010M200ST capacitors provide high ripple current, excellent AC performance, and low ESR (Equivalent Series Resistance), and are therefore a good choice for high frequency applications. The rated voltage of these capacitors is typically 200V, with temperature range from -25°C up to +85°C, and capacitance capacity typically ranging from 47uF to 1000uF.

The working principle of SEK010M200ST capacitors is the same as most other types of electrolytic capacitors. They consist of an anode and a cathode, each one immersed in an electrolytic solution. When a voltage is applied between the anode and cathode, positive and negative charges are generated in the aluminum foil that is present in between them. This creates a very high electric field in the aluminum foil, and thus provides a high capacitance of 47uF to 1000uF.

When the applied voltage is greater than its rated voltage, the SEK010M200ST is able to withstand the over-voltage and the excess voltage is dissipated in the form of heat. When the applied voltage is less than its rated voltage, the SEK010M200ST is able to maintain its capacity and continues to function properly.

In summary, SEK010M200ST capacitors are a type of aluminum electrolytic capacitors with a wide range of applications in audio power supplies, RF transmitters, and other high frequency circuits. They have excellent temperature and voltage stability, and their high capacitance makes them ideal for long-term use in high load applications. The working principle of this type of capacitor is based on the electric field generated by positive and negative charges created in the aluminum foil layers that are present between the anode and cathode terminals.
