Aluminum electrolytic capacitors (or aluminum electrolytic capacitor) are polarized units with a wide range of values and sizes. They contain a liquid electrolyte inside, and are widely used in power supplies, regulators and audio / electronic circuits. The EKZE800ELL471MM20S is a product from this field.

The EKZE800ELL471MM20S is a radial-leaded 2.0mm high, 0.8mm thick aluminum electrolytic capacitor with a lead pitch of 4.7mm. This aluminum electrolytic capacitor combines both high capacitance with low ESR and is compatible with a wide range of temperatures. It features a voltage rating of 50V, a capacitance of 6.8microF and a maximum ripple current of 169mA at 105°C.

Aluminum electrolytic capacitors are widely used in the market because of their excellent electrical properties and stability. As a result, they are found in a variety of applications, including power supplies, audio electronics, and switching regulators. The EKZE800ELL471MM20S, with its high capacitance and low leakage, is suitable for noise suppression, motor drives, and LED lighting applications.

The working principle of an aluminum electrolytic capacitor is based upon the principles of Faraday’s law. The capacitor is composed of an anode (positive), separator, electrolyte, and cathode (negative). When a voltage is applied across the capacitor, an electric field is created between the anode and the cathode. This electric field causes ions to move across the separator and accumulate on the anode. The reaction leads to the formation of a film on the anode that acts as a dielectric.

The anode and cathode of the aluminum electrolytic capacitor are separated by a membrane containing an electrolyte, which is a substance that can conduct electricity. The aluminum foil serves as the anode and the electrolyte bridges between the two materials. The electric charge builds up on the foils due to the electrolyte, which is known as the Faraday effect. The electric charge increases the stored energy in the capacitor–hence the capacitance.

The capacitance of aluminum electrolytic capacitors is highly dependent on the applied voltage, and thus it is not practical to use a single capacitor for all applications. This is why manufacturers offer a variety of voltage ratings, allowing users to select the appropriate device for their specific applications. The EKZE800ELL471MM20S is designed to be used in 50V applications, and its capacitance is 6.8microF.

Aluminium electrolytic capacitors are manufactured with special electrolytic solutions which can vary, most common ones are tantalum, conductive polymers and wet electrolytes. The wet electrolyte type includes non-polarized and polarized types. Aluminium electrolytic capacitors can be long life and they can also be tight tolerance, which are highly precise devices. The EKZE800ELL471MM20S is a tight tolerance, aluminum electrolytic capacitor, with excellent electrical properties, offering high capacitance and low leakage.

In summary, the EKZE800ELL471MM20S is an aluminum electrolytic capacitor for 50V applications that offers a high capacitance and low leakage. It is suitable for noise suppression, motor drives, and LED lighting applications due to its excellent electrical characteristics. Its working principle is based on the principles of Faraday’s law, and it is composed of an anode (positive), separator, electrolyte, and cathode (negative).
