Aluminum electrolytic capacitors are a type of capacitor that is widely utilized in electrical engineering and electronics circuits. They are often used to store an electric charge, stabilize voltage, control current, and act as filters in a variety of applications. This article will focus on the UPW1H2R2MDD aluminum electrolytic capacitors and will explore their application field and working principle.The UPW1H2R2MDD aluminum electrolytic capacitors are generally used for input and output decoupling applications in high-frequency switching supply circuits. This type of capacitor requires very low electric leakage, extremely high capacitance, and low ESR (Equivalent Series Resistance). They are also used in a variety of other applications, such as for filtering, bypassing, or decoupling DC power lines in power supplies, as well as for tuners, amplifiers, and digital circuits.The UPW1H2R2MDD aluminum electrolytic capacitors are composed of an anode and a cathode, which are connected by a dielectric layer. The anode is made of anodized aluminum foil and a gas-tight sleeve is attached to the outside. The cathode is composed of a cathode liquid, a conductive medium, and a porous paper insulation layer. The dielectric layer is usually made of a thin oxide film and acts as a separator. When a voltage is applied to the electrolytic capacitor, the thin oxide film is broken down and a dielectric is formed. This process creates a space charge that allows for the movement of electrons and the accumulation of electric charge, forming the basis of the capacitor’s operation.The UPW1H2R2MDD aluminum electrolytic capacitors provide excellent performance in a capacitance range from 100 µF to 10 µF, with a working voltage range from 2.5 VDC to 16 VDC. The rated ripple current is 40 mA at 100 kHz and the maximum leakage current is 5µA, making them ideal for decoupling applications. The capacitors are rated for a temperature range from -40°C to 85°C and operate with a temperature coefficient of +20%. Furthermore, they provide high capacitance stability and very low ESR values, making them a great choice for use in a variety of applications.Due to their robust design, the UPW1H2R2MDD aluminum electrolytic capacitors are widely used in many different applications. They are especially useful in the power supplies of electronics and electrical engineering circuits, as well as in amplifiers, digital circuits, motor control systems, and tuners. In all of their applications, these capacitors are effective in stabilizing the voltage and controlling the current, and can be used for filtering, bypassing, and decoupling power lines. To conclude, the UPW1H2R2MDD aluminum electrolytic capacitors are designed for high capacitance, low ESR, and low electric leakage, making them a suitable choice for a variety of electronic applications. They have a wide range of temperature coefficients and are able to operate in the temperature range of -40°C to +85°C. Furthermore, they provide excellent performance in decoupling applications, and in filtering, bypassing, and decoupling power lines in power supplies.
