UHD1A102MPD6

Aluminum electrolytic capacitors are polarized capacitors whose anode electrode is made of a pure aluminum foil with an etched surface. The aluminum forms a very thin insulating layer of thermally grown oxide that acts as the dielectric of the capacitor. The oxide layer can be very thin, on the order of tenths of a micrometer, yet still provide very good insulation and a relatively large capacitance. A special electrolyte covers the oxide layer. The electrolyte (which acts as the cathode) dissolves the oxide layer and allows a very thin oxide-electrolyte interface. This layered construction is what makes the aluminum electrolytic capacitor a polarized capacitor: the positive terminal is connected to the aluminum foil, and the negative terminal is connected to the electrolyte.

The UHD1A102MPD6 is an aluminum electrolytic capacitor commonly used in control, lighting, and power supply circuits. This specific type of capacitor is radial leaded with a maximum height of 15.5mm. It consists of a terminal cap, internal parts, and an insulating seal and is positioned with a “low impedance, low ESR” characteristic. As a result, it can deliver a large capacitance with low ESR. The UHD1A102MPD6 also has an operating temperature range of -55°C to +105°C.

The working principle of the aluminum electrolytic capacitor is relatively simple. The anode is made of aluminum foil which has been etched to increase its surface area. A layer of oxide is formed on the anode which acts as the dielectric medium. This layer is very thin and is only able to store a small amount of charge. The electrolyte then serves as the cathode and the two are separated by a porous paper separator. When a voltage is applied across the terminals of the capacitor, electrons will flow from the anode to the electroylte, creating a buildup of positive ions around the anode and negative ions around the electrolyte. This forces a buildup of electric charge and creates a potential difference between the anode and the electrolyte, allowing the capacitor to store an electric charge.

The UHD1A102MPD6 is a general-purpose aluminum electrolytic capacitor that can be used in a wide variety of applications. Due to its high capacitance and low ESR, it is ideal for use in power supplies, motor controls, and high-efficiency lighting circuits. It is also well-suited for industrial applications due to its wide temperature range, low size, and high reliability. The UHD1A102MPD6 also has a long life expectancy, making it a great choice for applications where long-term reliability is required.

In summary, the UHD1A102MPD6 is an aluminum electrolytic capacitor with a low impedance, low ESR design and a wide operating temperature range. It can store a large amount of charge in a small package, making it ideal for a variety of applications where high capacitance and long-term reliability are desired.
