Aluminum electrolytic capacitors can provide high capacitance value, high ripple current ability, good reliability and long lifespan in a relatively compact size. In recent years, these capacitors are gaining popularity to be used in a variety of applications from oil environments to automotive or medical sector. One sample of these capacitors is USF1E220MDD1TE with different specifications suitable for different kind of applications.

The USF1E220MDD1TE aluminum electrolytic capacitor belongs to a long form radial capacitor. It is a polarized device and it is marked in its body with “+” and “-” poles to identify its positive and negative terminals anodes. This capacitor is built in an aluminum body of 12.5×15 mm and its shape is long like a tube. It has a capacitance of 220 µF, a rated voltage of 16 DCV and its rated ripple current is 1.3 A, making USF1E220MDD1TE suitable for power supply for circuits with medium requirements.

In terms of its application field, USF1E220MDD1TE aluminum electrolytic capacitor is often employed in high voltage applications, such as automotive, oil, heater control, medical, lighting, and instrumentation. Additionally, its excellent temperature characteristics, long life, and low impedance make it a preferred choice for industrial and consumer electronics. Generally speaking, this capacitor is widely applied in UPS, computer power, medical and communication equipment.

When it comes to its working principle, the USF1E220MDD1TE aluminum electrolytic capacitor is generally composed of an anode, cathode, and an electrolyte. The anode is made of aluminum foil and the cathode consists of flexible aluminum foil and a tissue paper, which is soaked in the electrolyte. In acidic electrolytes, the anode is usually oxidized while in alkaline electrolytes, there might be a hydroxide coating that creates a barrier and prevents current leakage.

When a voltage is applied, the electrons flow from the cathode to the anode and electrolyte ions settle onto the aluminum component and form a barrier. The charge that is applied is stored on the surface of the components and held firmly as the oxidation layer prevents further leakage. To discharge the capacitor, one of the plates must discharge to the other and the charge is dissipated to the surroundings.

In conclusion, USF1E220MDD1TE aluminum electrolytic capacitor is a preferred choice for high voltage applications such as medical, automotive, instrumentation, and more. Its long life, excellent temperature characteristics, and low impedance make it suitable for various applications. With its working principle as described above, this capacitor is an efficient solution in order to provide reliable current flow for circuits with medium requirements.
