Aluminum electrolytic capacitors, also known as aluminum electrolytic polar capacitors, are polarized electrical capacitors. As its name suggests, the structure of the capacitor is composed of two aluminum foils, of which one is etched to form fine aluminum lamellar, connected to the external safety-pressure vent, as well as an electrolyte-soaked paper sealed by an aluminum case. The ULD1A221MED1TA, a common representative of polar capacitors, is a kind of aluminum electrolytic capacitor which has long been ranking the top in the capacitor market over its fantastic performance in terms of downtime, efficiency, capacity, and safety.

Aluminum electrolytic capacitors, such as ULD1A221MED1TA, are usually applied in low-voltage and high-current circuits requiring a large amount of storage energy to store electric energy and release it. They are ideal for a variety of uses including power supply smoothing in switching power supply systems, for filtering the audio signals that require a larger capacity of signals, and in the backup circuits for microprocessors and memory. In addition, the characteristics of ULD1A221MED1TA make them suitable for a broad range of applications, such as switching power supplies, audio amplifiers, frequency conversion power supplies, DC/DC converters, DC/AC inverters, LED drivers, etc.

With respect to ULD1A221MED1TA working principle, it is designed with two aluminum plates, separated by an electrolyte-soaked paper, with a thin oxide layer on the surface of the aluminum plate. When the working voltage is applied to the capacitor, electrons are transferred through the electrolyte and generated a negative charge in the oxide layer of the negative electrode and a positive charge in the oxide layer of the positive electrode. This results in electrons being drawn from the negative electrode to the positive side, building up a potential voltage between them. The electrons previously stored in the capacitor are consequently released. The amount of electrons in the capacitor is determined by its capacity, hence the capacity of an electrolyte determined the total amount of energy stored. The ULD1A221MED1TA is known for its excellent capacity, allowing it to store and release more energy than other similar products.

For an aluminum electrolytic capacitor, the amount of energy stored by the capacitor is a function of its capacitance as well as its working voltage. The ULD1A221MED1TA is designed with an enhanced withstand voltage of 35V, allowing it to store more energy for a given capacitance. In addition, the capacitor is highly regarded for its long product life and temperature stability due to its high-temperature sealing materials and self-healing electrolyte. These features, not only improve the reliability and safety of the capacitor but also extend its working life significantly.

In summary, the ULD1A221MED1TA is an excellent aluminum electrolytic capacitor in terms of reliability, safety, capacity, and energy-saving. It features an enhanced withstand voltage that allows more energy to be stored in the capacitor and has a long product life. Therefore, with these characteristics, this kind of capacitor is suitable for different applications including power supply smoothing, audio signal filtering, and backup circuits for microprocessors.
