Aluminum Electrolytic Capacitors

Aluminum Electrolytic Capacitors, referred to hereinafter as capacitors, have a wide range of applications and are found in many electronic devices such as computers and laptops. They are used as energy storage devices and have a wide range of uses from filtering high speed signatures to smoothing out audio signals.

The UHV0J221MDD capacitor is a specific type of electrolytic capacitor and is used for various applications. It is a polarize capacitor with a capacitance of 2200uF and voltage rating of 25V. The UHV0J221MDD has excellent frequency characteristics, allowing it to be used in high frequency circuits. It has excellent ripple current withstanding characteristics, low ESR, and low leakage current. It also has a long life and is excellent for high-frequency switching power circuits due to its good ripple current characteristics.

The UHV0J221MDD is suitable for applications such as switching power supplies, nuclear power plants, inverters, audio equipment, radio equipment, computers, automotive equipment, and measuring instruments. It has a reliable performance and is a cost effective solution for high-quality applications.

Working Principle of UHV0J221MDD Capacitor

The UHV0J221MDD capacitor works on the principle of electrolytic polarization. When direct current is applied to the capacitor leads, an anode and a cathode are formed by the electrolyte solution inside the capacitor. The anode side becomes the negative terminal and the cathode side becomes the positive terminal. When the voltage is applied to the capacitor, the dissociation that occurs in the electrolyte results in the formation of charges that provide the required capacitance for the capacitor.

The plates of the capacitor are made up of aluminum that acts as the anode, and oxide film on its surface. The oxide layer is an insulating barrier between the anode and the electrolyte solution inside. The aluminum oxide acts as an dielectric medium, which means it increases the capacitance of the capacitor. When a proper voltage is applied to the capacitor, the oxide layer is polarized and the capacitance of the capacitor is increased. This process is known as polarization and capacitance.

The UHV0J221MDD capacitor is also designed to provide higher ripple current than aluminum electrolytic capacitors of the same size and capacity. This can be attributed to the superior nature of the aluminum oxide layer, which increases the capacitance of the capacitor and eliminates excess heat dissipation. The ripple current can reach up to 10 times the rated capacitance and this makes the UHV0J221MDD capacitor suitable for high ripple current applications. The excellent ripple current withstands characteristics, low ESR and refresh time make the UHV0J221MDD capacitor one of the most reliable and cost effective solutions available.
