Aluminum Electrolytic Capacitors are an important type of capacitor. They are the key components of many electronic circuits and are widely used in almost all electronic devices. USR1E100MDD is one of the most common aluminum electrolytic capacitors. It is a high voltage aluminum electrolytic capacitor, which is mainly used in power supply for UPS, monitoring and telecommunications. In this article, we will discuss the application field and working principle of USR1E100MDD.

The USR1E100MDD aluminum electrolytic capacitor mainly has three main application fields: power measurement, power supply and AV system. In terms of power measurement, USR1E100MDD is mainly used for large-scale AC voltage and current measurement circuit in AC power system, current transformer and voltage transformer. In the field of power supply, USR1E100MDD is mainly used for filtering and rectifying circuit of power frequency and inverter. In the AV system, it can provide a perfect AC noise suppression, so that the signal quality is ensured. In addition, it can also be used in some special circuits.

The working principle of the USR1E100MDD is mainly based on the characteristics of the electrolyte. The electrolyte is a kind of liquid conductor, and its electrolysis capability can be affected by the applied voltage. As the voltage increases, the electrolysis capability of the electrolyte will also increase. The ions in the electrolyte will produce a positive and negative charge on both sides of the aluminum foil when an electric field is applied to the electrolyte. At this time, an electric double layer capacitor is formed, and the capacitance of the capacitor increases with the increase of the applied voltage.

The USR1E100MDD aluminum electrolytic capacitor has a casing made of aluminum foil, a film dielectric, an electrolyte and a polarized resistor. When an AC or DC voltage is applied to the capacitor, the thin oxide film on the aluminum foil surface breaks down. Due to the existence of the polarized resistor, the voltage drop of the capacitor is basically the same as the applied voltage, which can reduce the influence of the AC ripple voltage on the output voltage and reduce the voltage stress, extending the life of the capacitor.

The USR1E100MDD aluminum electrolytic capacitor has a number of advantages. It has a large capacitance, low equivalent series resistance (ESR), a high ripple current, good frequency characteristics and a wide temperature range. In addition, it has a low self-inductance and a high reliability, which makes it suitable for use in small size and high current applications.

In summary, the USR1E100MDD aluminum electrolytic capacitor is an important type of capacitor, and its main application includes power measurement, power supply and AV system. It has a wide temperature range and a high ripple current, and its working principle is mainly based on the characteristics of the electrolyte. It has excellent performance and is suitable for high current applications in small size.
