Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors, often referred to as electrolytic capacitors, are polarized capacitors consisting of an anode, cathode, insulating materials and an electrolyte. Electrically, these capacitors are made up of two metal plates that are insulated with a dielectric material. They are typically formed by using a thin sheet of aluminum metal that is electronically etched and the etched areas are then coated with a thin layer of glass paste, which is then dried in an oven. This process of creating an aluminum electrolytic capacitor is known as the etching method.

The B43698S5226Q1 is an aluminum electrolytic capacitors designed for high frequency and low ESR (Equivalent Series Resistance) applications. The capacitor has a rated voltage of 200V and working fully rated temperature range of -55 to +105°C. The B43698S5226Q1 comes in a compact package, with a diameter of only 22.5 mm and a height of 6.3 mm.

Working Principle

There are three main components in an aluminum electrolytic capacitor - the anode, the cathode and the electrolyte. The anode is an oxidized aluminum surface that serves as a plate. The cathode is a metal oxide or metal nitrite layer that contains a chemical solution and acts as an electrode. The electrolyte is a liquid solution which provides an ion bridge between the anode and the cathode. When an electrical voltage across the capacitor is applied, ions in the electrolyte move to the anode and cathode with the electrons traveling in the opposite direction.

When the voltage is applied, the electrolyte ions create a chemical reaction with the anode and cathode. This reaction creates an electrical current which causes the impedance of the capacitor to decrease, allowing the capacitance to increase. This means that the capacitor can be used to store energy for a specified amount of time.

Application Field

Aluminum electrolytic capacitors are most commonly used in audio equipment, due to their high capacitance and low impedance. These capacitors are also widely used for decoupling applications, such as power supplies, as they can provide rapid charge and discharge capabilities. They are also ideal for filtering purposes due to their high capacitance and low ESR value.

Another application for aluminum electrolytic capacitors would be in power electronics, such as voltage regulators and amplifiers. In these applications, the capacitor can be used to store energy and provide a steady voltage and current supply to the load. The capacitor’s low ESR value ensures that the voltage is maintained even in cases of high ripple current.

The B43698S5226Q1 aluminum electrolytic capacitor can handle a ripple current of up to 2.75A, making it ideal for use in high current applications. Due to its compact size, it is also suitable for use in confined spaces such as portable or embedded electronics.

In conclusion, the B43698S5226Q1 aluminum electrolytic capacitor can be used for a variety of different applications, such as audio equipment, decoupling applications, power electronics and more. Its high capacitance and low ESR value make it an ideal choice for a range of applications.
