Aluminum Electrolytic Capacitors
EEU-FR1E471Y Application Field and Working Principle
An aluminum electrolytic capacitor, also known as a Polarized Electrolytic capacitor, is a device consisting of two metallic electrodes separated by a nonconductive material called an electrolyte. Aluminum electrolytic capacitors feature high capacitance and low cost. They are commonly used in power electronic circuits and in RF applications. The capacitor is made of aluminum foil, a non-polarized dielectric material, and an electrolyte. The electrodes are then connected to the terminals of the capacitor.
Capacitance
The capacitance of a capacitor is a measure of the amount of electric charge it can store for a given voltage. Aluminum electrolytic capacitors feature high capacitance values, which makes them ideal for use in power electronic circuits or for other high-current applications. It is important to note that the capacitance of an aluminum electrolytic capacitor decreases with increasing frequency. For this reason, it is important to carefully select the right capacitor for a given application.
Voltage Rating
The voltage rating of an aluminum electrolytic capacitor is the maximum voltage that can be applied across its terminals without damaging the capacitor. It is important to consider the voltage rating when selecting an aluminum electrolytic capacitor for a given application. In general, aluminum electrolytic capacitors are available with voltage ratings ranging from 6V to 500V.
Temperature Coefficient
The temperature coefficient of an aluminum electrolytic capacitor is a measure of how the capacitance changes with temperature. In general, the capacitance of an aluminum electrolytic capacitor decreases as the temperature increases. The specific temperature coefficient for a given capacitor must be taken into consideration when selecting a capacitor for a given application.
Working Principle
The working principle of an aluminum electrolytic capacitor is based on the behavior of electrical charges in an electrolyte. When a voltage is applied across the capacitor, a current will flow and an electrostatic field will be created. This field polarizes the electrolyte, resulting in an electric dipole. The electric dipole causes charges to accumulate on the two electrodes, creating an electric field that stores the energy. This electric field is responsible for the capacitance of the capacitor.
Applications
Aluminum electrolytic capacitors are commonly used in power electronic circuits and in RF applications. They are also often used in power supply circuits, voltage regulators, motor drives and switching converters, and instrumentation circuits. Aluminum electrolytic capacitors are available with different capacitance values and operating temperature ranges, allowing them to be used in a wide variety of applications.
Conclusion
Aluminum electrolytic capacitors have a wide range of uses in power electronic circuits and RF applications. They feature high capacitance values, making them ideal for use in high-current applications. Additionally, aluminum electrolytic capacitors have a low voltage rating, making them suitable for use in many applications. It is important to carefully consider the capacitance, voltage rating and temperature coefficient of a given capacitor when selecting an aluminum electrolytic capacitor for a given application.
