Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are electronic capacitors primarily composed of two aluminum foils with an ionic conductive polymer membrane as the dielectric between them. The benefits of this type of capacitors are that they are relatively lightweight, have high energy density, and can be miniaturized to a considerable size. The two electrodes are rolled and connected and then sealed in a cylindrical can that is sealed with wax or resin to keep the capacitance value consistent. Many applications can use these aluminum electrolytic capacitors, such as audio tape recording and playback, boost and hold circuits, power-factor correction, and DC/DC converters.

LKG1H392MESBBK Application Field and Working Principle

The LKG1H392MESBBK is a tantalum electrolytic capacitor with a maximum temperature rating of 200°C. It is very suitable for medium power supply and can provide extremely low impedance and high ripple currents. In addition, its compact size makes it perfect for a variety of space-constrained applications, such as compact motor control and drills. This capacitor also features excellent stability and reliability that make it ideal for applications that require high-precision components. Furthermore, this series of capacitors is designed to operate over an extended temperature range of -55°C to +125°C.

In terms of working principle, aluminum electrolytic capacitors are polarized components with high capacitance that function based on the laws of electrochemistry. They usually require an applied voltage in order for their capacitance to be achieved. This electrical energy is stored in the electrolyte contained in the capacitor’s dielectric, which then dissipates over time. As the capacitor begins to discharge, the stored electrical energy is released in a reverse direction when the applied voltage is removed.

The LKG1H392MESBBK is equipped with polarized aluminum electrolytes and electrolytic capacitors with a low equivalent series resistance (ESR). It is capable of providing extremely low impedance and high ripple currents. Furthermore, this series of capacitors offers a high temperature stability and allows for the use of a wide temperature range of -55°C to +125°C. Moreover, the LKG1H392MESBBK is also equipped with a “snap-in” technology, which maintains a low equivalent series inductance (ESL) and reduces width of the capacitor profile.

The aluminum electrolytic capacitors contained in the LKG1H392MESBBK strictly follow the strict quality specifications. Each capacitor contains several thousand layers of aluminum foils, impregnated with a gel-like electrolyte containing a high-purity aluminum oxide film. This sedimentary film works as the dielectric between the two metal plates and provides a higher capacitive value for the capacitor. Its construction offers excellent stability and smaller size in comparison to the traditional tantalum capacitors.

The LKG1H392MESBBK is designed for a variety applications, such as digital equipment, DC/DC converters, audio tape recording and playback, power-factor correction, boost and hold circuits, and other applications with the need for an extremely low-impedance and high ripple currents. This capacitor series has become popular in the power supply and power conversion markets due to its excellent performance at high temperatures and its small size, which facilitates use in space-constrained applications.
