Aluminum electrolytic capacitors are the most widely used type of capacitors. They are used in a variety of electronic applications such as power supplies, audio equipment, and high-frequency circuits. The UVK1H4R7MDD1TA Aluminum Electrolytic Capacitor is one of the most popular models for its high capacitance, low equivalent series resistance, and miniaturization.

Application Field

The UVK1H4R7MDD1TA is mainly used for applications with high frequency and high temperature. It is suitable for high-frequency circuits, audio equipment, automotive electronics, and power supply applications. It is also suitable for high-temp, high-load, and high reverse-bias applications. With its excellent performance, this device is also used in other applications such as surge protection, AC noise filtering, and waveform simulation.

Working Principle

The UVK1H4R7MDD1TA is an aluminum electrolytic capacitor. It is composed of an electrolytic anode foil, a cathode foil, a separator, an electrolyte and a non-electrolyte. The two terminals of the capacitor connect to the anode and cathode foils respectively. The anode foil is electrically etched with fine zinc farad particles. The separator is made of dielectric paper that prevents metal ions in the electrolyte from short-circuiting the two foils. The electrolyte provides an electrolytic medium conductivity to the capacitor. The non-electrolyte is a viscous medium which provides insulation against failure between the farad particles and prevents arcing across the capacitor.

When voltage is applied across the terminals, the positive ions in the electrolyte migrate to the anode and the negative ions to the cathode. The electrolyte ionizates and forms an electric double layer at the anode and cathode. This generates a space charge field, which provides high capacitance. As the voltage increases, the ionic and electronic components of the capacitor behave linearly and become increasingly capacitive. The higher the voltage, the greater the capacitance.

This type of capacitor is extremely useful in high frequency and temperature applications due to its high capacitance and low equivalent series resistance. Because of its small size, it is easy to install and is often used in high temperature and high reverse-bias environments. It is also very reliable and cost-effective, making it a popular choice for many electronic applications.
