UPM1H2R2MDD1TD Capacitors

Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is an electronic component which utilizes the phenomenon of electrolysis between an aluminum foil and a non-aqueous electrolyte to enable electrical energy storage. This type of capacitor has a much higher capacitance than other types of capacitors.

UPM1H2R2MDD1TD Application Field and Working Principle

The UPM1H2R2MDD1TD aluminum electrolytic capacitor is a low-profile, radial-leaded, non-solid electrolytic capacitor with a wide range of applications. It is mainly used in high frequency circuits, such as inverters, power converters, motor speed controllers, motor drivers, and amplifier circuits. The capacitor features high capacitance, low ESR, low DF and long life.

In order to understand the working principle of the UPM1H2R2MDD1TD capacitor, it is necessary to understand the basics of electrolytic capacitors. An electrolytic capacitor is a type of capacitor that consists of two metal or conductive plates separated by a dielectric material. The two metal plates are electrolytes and the dielectric material is a non-aqueous electrolyte. The plates are connected to the positive and negative connections of an electrical power source. When a voltage is applied, the electrolyte passes electric current through the metal plates, causing an ionic reaction which creates a capacitance. This capacitance changes as the voltage is increased or decreased, thus allowing voltage to be stored in the capacitor.

The UPM1H2R2MDD1TD aluminum electrolytic capacitor uses an aluminum foil folded into a cylindrical bank as its electrolyte, so that it can achieve a high capacitance rating. The aluminum plate of the capacitor is anodized, meaning that the anode of the capacitor is smaller than the cathode. This allows the capacitance of the capacitor to increase as the voltage is increased. The anodizing process also helps the capacitor to better repel moisture and other contaminants.

In order to increase its life cycle, the UPM1H2R2MDD1TD capacitor also has a low ESR (equivalent series resistance). This low ESR helps to reduce the amount of power dissipated during charging and discharging cycles, which in turn helps to increase the capacitor’s life. The capacitor also has a low DF (dielectric absorption), which ensures that the energy stored in the capacitor is quickly made available to the circuit when it is discharged.

The UPM1H2R2MDD1TD aluminum electrolytic capacitor is often used in high frequency circuits, such as inverters, power converters, motor speed controllers, motor drivers, and amplifier circuits. The capacitor’s high capacitance, low ESR and DF, and long life make it an ideal choice for these types of applications.
