672D187H050DM5C

Aluminum Electrolytic Capacitors are widely used in a variety of applications, often for the purpose of energy storage. The specific device model 672D187H050DM5C is a high voltage class aluminum electrolytic capacitor, designed with capacitance of 187µF and rated operating temperature of 105°C. It has a wide temperature range from -40 to +105°C, an extended life of up to 3000 hours, and a rated voltage of 50VDC.

Aluminum electrolytic capacitors are classified as polarized capacitors, meaning that one of their plates must be connected with positive polarity and the other with negative polarity. This is necessary because aluminum oxide, the dielectric material, can only form on the surface of the aluminum dielectric, due to an electrolytic charging process that takes place when the capacitor is connected to a voltage source. When polarity is reversed, the oxide layer is destroyed and the capacitor will no longer work.

The 672D187H050DM5C device is constructed using two layers of aluminum foil, one for each plate, separated by paper saturated with various types of electrolyte, which acts as the dielectric. The device is then rolled up and inserted into a plastic or metal can, creating a cylindrical shape. The can is then sealed and hermetically sealed to protect the device from any external influences. The 672D187H050DM5C device can thus be considered a “tubular” type of aluminum electrolytic capacitor.

The 672D187H050DM5C device has many applications, among them are: filtering, coupling and bypass applications in electronic equipment, such as radio broadcast transmitters, commercial airline radio communication systems and radar systems; in low- and high-frequency power supplies and switching power supplies, low-pass and high-pass filters; in IGBTs and diacs; on general-purpose boards of large power systems; and in voltage hold ups for automobiles, solar power plants and other similar applications.

The working principle of the 672D187H050DM5C aluminum electrolytic capacitor is simple and relies on basic electrochemical principles. When the capacitor is connected to a voltage source, electrons flow from the negative plate into the electrolyte, causing a chemical reaction between the electrolyte and the aluminum foil. This reaction forms a thin layer of aluminum oxide, which acts as an insulator, preventing further electron flow. At the same time, the positive plate will accumulate electrons, creating an electric field. This allows the capacitor to store energy for a short period of time by utilizing the electric field.

In conclusion, the 672D187H050DM5C aluminum electrolytic capacitor is a high voltage polar capacitor, suitable for a range of applications for filtering, coupling and bypass. Its working principle relies on basic electrochemical principles, where electrons are drawn into an electrolyte, reacting to form a thin layer of oxide that acts as an insulator, allowing the capacitor to store energy in the electric field. As such, this device is an invaluable component in modern electronics.
