Aluminum electrolytic capacitors are electrochemical devices that use two aluminum foils that are oxidized and spaced by a separator soaked in an electrolyte. The aluminum is oxidized to form a porous dielectric layer in between the two parts. The dielectric layer acts as an insulator between the positive and negative sides of the capacitor, thus allowing it to store a charge. The LNT2C682MSEN aluminum electrolytic capacitor is a capacitor that utilizes an extended temperature range of -55°C to 105°C and offers increased capacitance for applications in extreme temperature environments. It is often used in switch-mode power supply transformers and as a power supply bypass capacitor where extra capacitance is beneficial.

The LNT2C682MSEN is a surface-mount aluminum electrolytic capacitor with a rated voltage of 25V and maximum operating temperature of 105°C. It has a voltage coefficient of 0.1 %/V, capacitor range of 130µF to 330µF, and a life expectancy of 2000 hours at 105°C. The LNT2C682MSEN has a ripple current rating of 400mA ⁄ 600mA, and can handle peak current up to three times the ripple current rating. It also has a low ESR of 8mΩ ⁄ 30mΩ at 100kHz.

The LNT2C682MSEN aluminum electrolytic capacitor has a special design that enables it to work in extreme temperatures, making it suitable for applications that require reliable and stable operation. This type of capacitor is commonly used in automotive and industrial systems, lighting systems, electric power supplies, and consumer electronics. Its low ESR combined with its extended temperature range also makes it well suited for high frequency applications, such as dc-dc converters, inverters, and MP3 players.

The LNT2C682MSEN does not require periodic maintenance and is designed for fast-acting protection against overvoltage spikes due to its polar design. It also has a self-healing feature that allows it to automatically recombine and restore the severed dielectric layer created by the overvoltage spike. This makes the LNT2C682MSEN an ideal choice for applications where overvoltage protection is a primary concern.

The working principle of the LNT2C682MSEN aluminum electrolytic capacitor is relatively simple. The two aluminum foils are oxidized and separated by a separator soaked in a specialized electrolyte. When a voltage V is applied between the aluminum foils, a current I flows through the separator. This current causes an accumulation of ions in the electrolyte, which increases the capacitance. As the voltage across the capacitor increases, the capacitance increases, thus providing more effective current filtering and storage.

The LNT2C682MSEN aluminum electrolytic capacitor is a versatile and reliable device that is able to handle high currents and work in extreme temperature environments. It is an ideal choice for applications that require increased capacitance and overvoltage protection, such as automotive and industrial systems, lighting systems, electric power supplies, and consumer electronics.
