Aluminum electrolytic capacitors are physically the largest and most cost-efficient type of capacitor, due to the large size of their plates, which enables a large capacitance to be obtained in a single device. 688TTA016M is an aluminum electrolytic capacitor with a capacitance of 6.8uF and a rated DC working voltage of 16V. It is widely used in various kinds of electrical and electronic products, including power supplies, telecommunications, audio equipment and computer components.

Application Field

The 688TTA016M aluminum electrolytic capacitor is mainly used in applications requiring large capacitance values and rated DC working voltages. In general, they are used to smooth out power from a DC power supply. When a DC power supply is connected to an AC load, it will cause some voltage fluctuations, and an electrolytic capacitor is used to reduce the fluctuations and improve the voltage quality.

The 688TTA016M can also be used for other applications such as timing circuits, filter circuits, and circuit protection. They are often used in the reset circuits of microcontrollers, which require the presence of a large capacitance to provide enough power in a very short time from the power supply.

In addition, this aluminum electrolytic capacitor is also applicable in motorcycle and automotive alternators, auxiliary power supplies, audio equipment, and other high-power supply context.

Working Principle

The 688TTA016M aluminum electrolytic capacitor consists of two aluminum foil plates separated by a thin oxide layer and soaked in an electrolyte solution. The two plates are etched with a pattern of squares which increases the surface area exposed to the electrolyte, thus increasing the capacitance. Since the oxide layer prevents electrons from flowing between the two plates, the charge is trapped inside the capacitor, resulting in a capacitive effect.

The 688TTA016M aluminum electrolytic capacitor is also known as a polarized capacitor. This means that it can only be connected to a power supply in one direction, with the positive side connected to the positive terminal, and the negative side connected to the negative terminal. This ensures that the oxide layer is consistently charged and that no current leaks out of the capacitor.

When a voltage is applied across the terminals of the 688TTA016M aluminum electrolytic capacitor, an electric current passes through the electrolyte. This is known as the ‘charging current’, which charges up the oxide layer between the two plates, thus creating a charge often referred to as ‘capacitive energy’. When the power source is disconnected, the current flows back through the electrolyte, and this charge is discharged.

The 688TTA016M aluminum electrolytic capacitor is designed to handle larger amount of current compared to other types of capacitors. This is because they are constructed with thicker plates, which increases the energy storage capacity of the device. They also have a higher working voltage and longer service life.

The 688TTA016M aluminum electrolytic capacitor is a low-cost and highly efficient capacitor that can be used in a wide range of applications. The large capacitance and rated DC working voltage of the device make it suitable for use in many different types of electronic and electrical equipment, as well as automotive and industrial machines.
