SEK330M025ST

Aluminum electrolytic capacitors are capacitors which make use of a pair of aluminum foils that are etched with a pattern of concentric circles, and one of them is then rolled into a cylinder or “can”. One of the pieces is an electrically insulating material forming the dielectric. This electric field between the conductive plates, repelling electrons in the metal plate on the outside of the roll. These Repulsive electrons are pushed into the area between the plates, forming capacitor plates.

The SEK330M025ST is a type of aluminum electrolytic capacitor offered by Panasonic. It has a capacitance rating of 330MF and a voltage rating of 25V. The SEK330M025ST is designed to be used primarily in general-purpose applications, such as filtering, coupling, and decoupling. It is also suitable for use in high frequency switching power supply circuits.

The SEK330M025ST capacitor has a leakage current rating of only 0.3 microamps at 25 volts. This low leakage current makes it ideal for applications where low leakage currents are imperative, such as in pulsed power circuits. It also has an excellent temperature range of -40 to + 85 degrees Celsius, making it suitable for use across a wide range of temperatures.

Working Principle: The SEK330M025ST works by using electrolytic action. Metal ions in the electrolyte solution react to the electrical current between the capacitor plates, forming a layer of oxide on the surface of the plates. This oxide layer acts as the dielectric, creating a capacitance to store electrical energy. As electric charges are applied to the capacitor, an electric field is created which repells electrons in the metal plate on the outside of the roll. The electrons are pushed into the area between the plates, forming capacitor plates.

In addition, the SEK330M025ST also has some of the highest ripple current ratings available, making it exceptionally well suited for use in power supply circuits. The capacitor is very reliable with a long life ratings of up 5000 hours at 105 degrees Celsius, making it ideal for use in high-temperature applications.

The SEK330M025ST aluminum electrolytic capacitor is a reliable and economical choice for a variety of general-purpose applications. It has a low leakage current rating, high ripple current ratings, an extended temperature range, and a long life rating, allowing it to meet the needs of various industrial, automotive, and other applications.
