Aluminum Electrolytic Capacitors

UKW2A4R7MDD1TA Application Field and Working Principle

Aluminum electrolytic capacitors, also known as electrolytic capacitors or aluminum electrolytic capacitors, are a type of passive components that stores electric energy and releases it when necessary. They are quite common in electronic circuits and play an important role in signal filtering, smoothing and voltage stabilizing, and are usually used in combination with other electronic components. The UKW2A4R7MDD1TA is one of the major series of aluminum electrolytic capacitors, which is suitable for both high and low temperature applications. In this article we will discuss its application field and working principle.The UKW2A4R7MDD1TA is a polarized aluminum electrolytic capacitor series, and it can be used in many applications of electronic engineering, such as computers, audio equipment, mobile phones, home appliances, etc. The series has a voltage range of 0.1V to 0.33V and a capacitance range of 0.1µF to 1000 µF, offering wide selection to meet customer requirements. A typical aluminum electrolytic capacitor consists of a pair of aluminum plates each separated by a substrate, making up the main and subsidiary parts of the capacitor. The main part of the aluminum electrolytic capacitor is an anode of aluminum sheet that has been treated electrochemically to form an oxide. The anode is pre-connected to a metal case that also acts as a cathode. The oxide layer is very thin and breaks down easily, releasing large electric current. This phenomenon is referred to as “dielectric breakdown”. The UKW2A4R7MDD1TA series aluminum electrolytic capacitor is a high stability and reliability series, which can be used in high and low temperature environments. The working temperature range is from -55°C to +105°C, and the ripple current is 4 times of the rated one. The capacitor also has high density, ensuring that the capacitor has a large capacitance value in a small space, providing a great advantage for applications where space is limited.The working principle of a UKW2A4R7MDD1TA aluminum electrolytic capacitor is quite simple: When voltage is applied to the two electrodes, an electric current flows through the electrolyte which induces an electric field around the electrolyte. This field disturbs the electrons on the surface of the metal oxide, breaking down the oxide layer. The electrons are then attracted to the positive and negative electrodes, forming a current loop. This capacitor works as usual when the applied voltage is within the working voltage range which is rated on the data sheets.In summary, the UKW2A4R7MDD1TA aluminum electrolytic capacitor series is a kind of strong and reliable electric components, which have many advantages such as high stability, reliability and wide range of voltage and capacitance. It is often used in many kinds of electric circuits, such as computers, audio equipment, mobile phones, home appliances, etc. Its simple working principle makes it easy to use and maintain, which makes it the ideal capacitor for a wide range of application fields.
