Aluminum Electrolytic Capacitors are polarised capacitors with aluminum oxide dielectric and solid electrolyte, commonly used in electronic circuits for decoupling, signal filtering and various other processing functions. The LAK2G680MELB20 is a member of the aluminum electrolytic capacitor family, and is a surface mount device intended for use in a variety of applications, specifically for its low ESR characteristics.

The LAK2G680MELB20 is a surface mount aluminum electrolytic capacitor with a diameter of 2.5mm, a height of 4.0mm and a rated voltage of 6.3V. In its standard configuration, it features an extended ESR value of just 68mR, allowing for greater filtering and parallel operation capabilities. It also features a working temperature range of -55 to +105°C, and a rated capacitance of 220μF.

The LAK2G680MELB20 is typically used in any device that requires a low ESR operating voltage and medium- to low-temperature operation. This includes high-speed processors, low-noise amplifiers, digital signal processors, time-critical circuits, etc. In addition, its low profile and small footprint makes it ideal for use in portable and other space-restricted devices.

The working principle of the LAK2G680MELB20 is based on the principle of a parallel capacitance configuration. Upon application of a voltage across the two terminals of the capacitor, an electric current is produced due to the capacitance of the polarized aluminum oxide dielectric. This electric current produces a field of induced charge polarization within the electrolytic that further increases the electric field within the dielectric. This, in turn, produces a stronger stored energy that is released upon removal of the initial electric field.

The LAK2G680MELB20 also features a non-polar capacitor configuration, which eliminates any risk of damaging one of the capacitor\'s plates, as there is no preferential direction of the electric current. This makes the aluminium electrolytic capacitor considerably more durable and reliable than its counterparts.

Finally, given its extended ESR value, the LAK2G680MELB20 is considered to be the most cost-effective aluminum electrolytic capacitor on the market today. As such, it is a popular choice for applications that require a long life span and enhanced electrical performance.
