Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are a type of capacitor that relies on the polarity of a thin foil anode and cathode aluminum to create a stored charge. The anode metal is electrolytically oxidized to form a porous layer of aluminum oxide. This aluminum oxide layer acts as a dielectric, resulting in a very strong electrical field between the anode and the cathode. This strong electric field is responsible for storing electrical energy when the capacitor is charged.Aluminum electrolytic capacitors are widely used in many different applications, from low frequency AC circuits, to high frequency digital circuits, to DC power supplies. They are especially common in applications that require high capacitance, such as in power supplies for personal computers, mobile phones, and other electronic devices.The UHD1A221MED1TA is an aluminum electrolytic capacitor manufactured by Vishay Intertechnology. It is designed for use in applications that require high capacitance, such as power supplies and AC circuits. It is offered with rated capacitance of 21000uF, vrating of up to 450V, and operating temperatures of -40°C to +125°C.The UHD1A221MED1TA is a post-type, non-polarized capacitor. Its post-type design makes it easy to mount in through-hole or pc board applications. It has a high surge capability, endurance, and low ESR, making it suitable for use in power supplies and AC circuits.The UHD1A221MED1TA has a cylindrical aluminum case, anode terminals, and a cathode terminal. Its dielectric is a chemically formed aluminum oxide, which is optimized for reliability and high capacitance values. Its cathode terminals are soldered to the base of the capacitor, and its anode terminals are soldered to a plate that is inside the capacitor.When voltage is applied to the UHD1A221MED1TA, the electrical charges are stored on the plates, and a current flows through the dielectric to charge the capacitor. This current is responsible for storing electrical energy in the capacitor. When the current is removed, the capacitor discharges, transferring its stored energy back into the circuit.In conclusion, the UHD1A221MED1TA is an aluminum electrolytic capacitor designed for use in power supplies and AC circuits where high capacitance values are needed. It offers a low ESR, high surge capability, and excellent endurance, making it suitable for many commercial, industrial, and consumer applications.
