LKS1H392MESA Application Field and Working Principle

Aluminum electrolytic capacitors are one of the more common types of capacitors, and are widely used in electronic circuits. The LKS1H392MESA is a product of this type of capacitor that is made by Shenzhen Luokexin Electronics and has a large variety of application fields.

Overview of LKS1H392MESA Aluminum Electrolytic Capacitor

The LKS1H392MESA has dimensions of 39mm x 25.4mm and a voltage rating of 2.5V. It has a capacitance of 330uF, a rated ripple current of 250mA, an impedance of 45 Omega, and a maximum tangential elasticity of 470MV/mFS. The capacitor is made from a special aluminum oxide film electrolyte and has an electroplated, pure tin cathode lead, with a tin-plated ring and a paper sleeve. This capacitor has good shock-proof, vibration-proof, high temperature, and large current characteristics, and is very suitable for use in power electronics and automotive electronic components.

Working Principle of LKS1H392MESA Aluminum Electrolytic Capacitor

Aluminum electrolytic capacitors work by using the electrolyte material to create a surface charge between two conductors, in this case aluminum and tin. When a voltage is applied to the capacitor electrodes, the range of electrical charges in the electrolyte create an electrical charge on the aluminum substrate, creating an electric field on the surface of the aluminum. This electric field is responsible for storing the energy in the capacitor.

When the voltage is removed, the aluminum loses its charge and the excess positive or negative ions in the electrolyte balance each other out, leaving the capacitor at its initial charge. The rate at which the charge is changed depends upon the electrolyte material, and its properties such as its dielectric constant and dissipation factor.

For the LKS1H392MESA, the aluminum oxide film electrolyte has a dielectric constant of 6.5 to 8.5 and a dissipation factor of 2% to 4%, depending on the operating temperature. This combination of properties ensures that the capacitor can handle large flow currents while maintaining a low ESR (equivalent series resistance). This makes them ideal for use in applications where rapid charge and discharge cycles are required.

Applications of LKS1H392MESA Aluminum Electrolytic Capacitor

The LKS1H392MESA is primarily used in power electronics and automotive electronic components, but it is suitable for many other applications as well. It has a wide operating temperature range of -55°C to +105°C, making it suitable for use in high temperature environments, such as in engines. It also has a wide capacitance range and low ESR rating, making them ideal for use in applications that require rapid charge/discharge cycles.

The LKS1H392MESA is also used in audio systems, LCD and LED displays, solar cells, high frequency switching networks, and switching power supplies. It has a long life span, making it suitable for use in applications where power supply needs to be maintained for an extended period of time.

Overall, the LKS1H392MESA aluminum electrolytic capacitor is a versatile and reliable product that is suitable for a wide range of applications, particularly in power electronics and automotive applications. Its long life span and ability to handle large charge and discharge cycles make it an ideal choice for high-performance applications.
