Aluminum electrolytic capacitors, or simply electrolytic capacitors, are a type of capacitor whose capacitance is much larger than ceramic capacitors. This type of capacitor typically contains two aluminum foils, one etched to form a pattern of parallel plates, and separated by a piece of paper soaked in electrolytes. An electric current is used to polarize the aluminum foils, forming an electric field in between them. The electric field increases the capacitance of the capacitor.

The SXR121M100ST capacitor is a radial type aluminum electrolytic capacitor with a maximum voltage of 63 VDC. This capacitor has a capacitance range between 2.2µF to 470µF, a rated operating temperature range of -40°C to +85°C, and a tolerance of ±20%. Furthermore, the SXR121M100ST has an ESR of 0.16Ω at 1KHz and a 104 dB insulation resistance.

The SXR121M100ST application field includes DC-Link capacitor, energy storage for power electronics systems, and filter noise suppression circuits. This capacitor is mainly used in applications which require high capacitance with small physical size. It can also be used in power supplies, light ballasts, power switching applications, and other decoupling applications.

The working principle of the SXR121M100ST is based on the principles of electrochemistry. When a DC voltage is applied to the leads of the capacitor, a current flows through the electrolyte, which then accelerates the formation of an aluminum oxide film on the plates inside. This oxide film is a good dielectric material that separates the two plates, thus increasing the capacitance of the capacitor.

The SXR121M100ST capacitor also has an enhanced reverse current characteristic which helps to protect against over current and heat generation. This feature extends the life of the capacitor and makes it well suited for applications that require long-term stability of electric components.

The superior lifespan and small size of the SXR121M100ST make it a great choice for applications where large amounts of capacitance are required in a small package. Due to its robust construction, reliability, and long life, it is suitable for use in a wide variety of applications such as power supplies, DC link capacitors, energy storage, and filter noise suppression circuits.
