Aluminum electrolytic capacitors, also known as electrolytic capacitors, are capacitors with an anode made of an aluminum foil and an electrolyte in the form of a gel or liquid. These capacitors are used in a variety of applications, such as signal filtering, power filtering, timing circuits, and the like. This type of capacitor can offer good performance at both low and high frequencies, making them suitable for a wide range of applications. The ALF40C181DF450 is one example of an aluminum electrolytic capacitor.
The ALF40C181DF450 is a surface mounted aluminum electrolytic capacitor, designed for general purpose applications. The capacitor is constructed with an aluminum foil anode, an electrolytic gel for the dielectric, and a molded polymer case for mounting. The terminations are specified as radial with Solder plates.
The ALF40C181DF450 has a capacitance of 47µF and a rated voltage of 25Vdc. Its temperature range is -55 to +105°C. In addition, the rated dissipation factor is 0.2% with a maximum leakage current of 0.05µA at 20°C. This capacitor is suitable for operation at frequencies from 10Hz to 1MHz and has a life expectancy of up to 5000 hours under normal operating conditions.
The ALF40C181DF450 is widely used in consumer electronics, automotive electronics, and industrial applications where its electrical and physical characteristics make it an ideal choice. Its large capacitance in combination with its low ESR and long life allow it to be used in a variety of applications, such as signal coupling, power smoothing, and timing circuits. In addition, its low profile makes it suitable for use in high density printed circuit board applications.
The working principle of an aluminum electrolytic capacitor is fairly simple. When current passes through the capacitor, a small amount of voltage is applied across the anode and cathode. This voltage causes a reaction between the aluminum and electrolyte, forming an insulating oxide layer on the aluminum foil. This insulating layer, called the dielectric, prevents current from flowing through the capacitor, thus creating a charge separation that is known as capacitance. When a voltage is applied to the terminals of the capacitor, electrons can pass through the dielectric, storing energy in the form of an electric field.
In summary, the ALF40C181DF450 is an aluminum electrolytic capacitor designed for general purpose applications. It offers good performance at both low and high frequencies, with a capacitance of 47µF and a rated voltage of 25Vdc. Its temperature range is -55 to +105°C and the rated dissipation factor is 0.2% with a maximum leakage current of 0.05µA at 20°C. This capacitor is suitable for frequencies from 10 Hz to 1 MHz and its low profile makes it suitable for high density printed circuit board applications. The working principle of an aluminum electrolytic capacitor relies on an anode made of aluminum foil and an electrolyte, forming an insulating oxide layer known as the dielectric to create charge separation.
