Aluminum electrolytic capacitors, also known as “aluminum electrolytic capacitors”, are capacitors in which aluminum as the anode is chemically etched on the surface of aluminum foil and then wrapped with an electrolyte-soaked impregnated paper (dielectric paper) is wound into a cylinder, and two uncoated aluminum plates are sealed as a negative electrode and a positive electrode respectively. The aluminum electrolytic capacitors have the characteristics of large capacity, small size, light weight, low equivalent series resistance (ESR) and excellent equivalent series inductance (ESL), and are widely used in a variety of electronic circuits. UHE1H181MPD1TD is a kind of aluminum electrolytic capacitor and its application field and working principle will be further discussed in the following.

UHE1H181MPD1TD is an Ultra Low Impedance Aluminum Solid Electrolytic Conductive Polymer Capacitor from the 100μF to 330μF value range with a rated voltage of 10Vdc, having an 85 C maximum operating temperature and a life expectancy of 3000 hours at 85 C and 10Vdc. Being a polymer aluminum capacitor, UHE1H181MPD1TD offers low ESR and ESL for a wide range of decoupling, filtering and storage requirements. The application field of UHE1H181MPD1TD is mainly in decoupling, DC filtering, output/input fault protection and energy storage. Common applications include power supplies, systems related to motors, etc.

The working principle of UHE1H181MPD1TD is the same as the basic principle of other aluminum electrolytic capacitors. Firstly, oxygen and water molecules react with the aluminum foil of the capacitor, forming a layer of porous and disordered aluminum oxide layer. Secondly, a thin layer of activated electrolyte is coated on the surface of the aluminum oxide layer, forming a porous conductive medium. Thirdly, and most importantly, electrons can pass through the electrolyte, so that the separated aluminum foil can form an electric double layer, i.e. one of the capacitive substances. Therefore, when the UHE1H181MPD1TD aluminum electrolytic capacitor is connected in series, the electric double layer on the inner and outer surfaces of the positive and negative aluminum foils will form an electrical connection and store energy through the intervening electrolyte.

In the process of using UHE1H181MPD1TD, special attention should be paid to the operating temperature and voltage of the capacitor. Under the condition of constant temperature, the higher the voltage, the larger the leakage current of the capacitor will be, thus reducing the service life of the capacitor under normal operating conditions. In addition, the temperature of the device should also be properly controlled. When the operating temperature of UHE1H181MPD1TD capacitor is too high, the electrolyte in the device will quickly evaporate, which will also reduce its service life. Therefore, when the aluminum electrolytic capacitor is operating, it is necessary to ensure that the temperature is between the working temperature and the maximum operating temperature indicated by the device data.

In conclusion, as a kind of aluminum electrolytic capacitor, UHE1H181MPD1TD has the advantages of low ESR, low ESL, wide temperature range and wide voltage range. Its application field is mainly in the fields of decoupling, filtering and storage, and its common applications include power supply and motor use systems. In addition, UHE1H181MPD1TD has a relatively simple principle of operation, which depends on the reaction of aluminum and oxygen and the formation of an electric double layer via the corresponding electrolyte. In the actual operation, special attention should be paid to the temperature and voltage of the device.
