Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors use a solid conductor which is usually aluminum foil along with an electrolyte, typically a type of liquid or gel, as a dielectric. It is the combination of these elements which gives the aluminum electrolytic capacitor its positive and negative characteristics. The positive aspect is that it can store a lot of charge in a relatively small package and the negative aspect is that it has relatively poor capacitance stability and tends to have a relatively short life span.

The UBT2W220MHD1TN aluminum electrolytic capacitor is an extremely reliable and highly efficient capacitor available in a variety of voltages and capacitance sizes. It features a cylindrical aluminum housing, a snap-in mounting feature and an 8mm pin lead spacing, making it ideal for a wide range of applications.

Application Field

The UBT2W220MHD1TN aluminum electrolytic capacitor is suitable for a wide range of applications, including signal conditioning circuits, filtering, and energizing coils or transformers in devices such as televisions, power supplies, audio-visual equipment, and industrial equipment. It also has a wide temperature range and can be used in both high temperature (up to 125°C) and low temperature (down to -40°C) environments. Additionally, the capacitor can support high ripple currents, making it a great choice for high-frequency, high-power applications.

Working Principle

The working principle of the UBT2W220MHD1TN aluminum electrolytic capacitor is that an electric field is created using an anode and a cathode. The anode is made out of aluminum foil, and the cathode is a semi-permeable membrane containing an electrolyte, typically a type of liquid or gel. The aluminum foil is sandwiched between two layers of the electrolyte and the two layers are separated by a gas layer. When electricity is applied to the capacitor, the voltages at the anode and the cathode cause an electrolysis reaction, which results in the buildup of ions along the two sides. The buildup of ions creates an electrical field, called capacitance, which stores the energy.

The stored energy can then be released back into the circuit as needed. The capacitance of the UBT2W220MHD1TN capacitor depends on the size and composition of the capacitor, as well as the temperature and the frequency at which it is operating. Additionally, some aluminum electrolytic capacitors may have temperature compensation or other features to increase their reliability and performance.

Overall, the UBT2W220MHD1TN aluminum electrolytic capacitor is a reliable, highly efficient, and cost-effective capacitor that is suitable for a wide range of applications.
