Aluminum Electrolytic Capacitors - LNR1C474MSEN Application Field and Working Principle

An aluminum electrolytic capacitor, also known as an aluminium electrolytic capacitor, is an electrolytic capacitor with an electrolyte of aluminum oxide and an anode of aluminum foil. It is a passive two-terminal electrical component that stores electrical energy in an electric field. Aluminum electrolytic capacitors are commonly used in electronic circuits as well as power supplies and motor control applications.The LNR1C474MSEN aluminum electrolytic capacitor is a non-polarised capacitor with a capacitance value of 47 uF and a voltage rating of 25V DC. This type of capacitor is typically used in DC power supplies and motor drives. The rated working temperature range for this type of capacitor is between -40°C and 85°C and the voltage coefficient is rated to 250V AC. The construction of the aluminum electrolytic capacitor consist of three main parts: an anode of aluminum foil, a cathode of electrolyte, and a separator of dielectric oxide film. The aluminum foil is etched with v-shaped grooves called anodes, which increase the effective surface area of the aluminum foil and hence increasing the capacitance. The electrolyte is usually a solution of sulfuric acid and water, and helps to provide a continuous connection between the anode and cathode. The working principle of aluminum electrolytic capacitors is similar to that of polarized capacitors. An electric field is formed between the anode and cathode when the capacitor is connected to a DC power source. As charges accumulate on the aluminum anode, they attract and hold molecules of the electrolytic solution. This forms a dielectric layer between the anode and cathode, providing a large capacitance. When the capacitor is connected to an AC power source, the charges on the anode and cathode alternately attract and repel each other, allowing the capacitor to store energy in the form of an electric field. The main disadvantage of aluminum electrolytic capacitors is their relative short lifespan, which can be shortened by factors such as higher temperatures, higher working voltage and higher ripple currents. The LNR1C474MSEN aluminum electrolytic capacitor is typically used in DC power supplies and motor drives, where its good capacitance characteristics and stability makes it an attractive option. The high voltage tolerance of this type of capacitor makes it suitable for use in applications where the working voltage exceeds the capacitor\'s rated voltage. The long shelf life and low leakage current of the LNR1C474MSEN also make it suitable for use in high temperature applications. In conclusion, the LNR1C474MSEN is a high quality aluminum electrolytic capacitor with a capacitance of 47uF, a voltage rating of 25V DC and a working temperature range of -40°C to 85°C. It is suitable for use in applications requiring high voltage tolerance, long shelf life and low leakage current.
