Aluminum Electrolytic Capacitors: UTS1H100MDD1TE Application Field and Working Principle

Aluminum electrolytic capacitors are widely used in various electronic circuits of electronic products due to their excellent performance and lower cost. The UTS1H100MDD1TE is a type of aluminum electrolytic capacitor developed by AVX. It is mainly composed of aluminum, anode and electrolyte. The capacitance of this capacitor is 100uF and its rated voltage is 25V, making it suitable for various electronic circuits and applications.

Application Field

UTS1H100MDD1TE are mainly used in electronic circuits such as power supplies, signal filters, oscillators, voltage regulators, electronic toys and other electronic products. Due to their high capacitance and low internal resistance, they can be used to filter the output signal of the power supply to make the output voltage stable and prevent noise signals, which can improve the performance of electronic products. In addition, this type of capacitor is also widely used in linear power supplies, interference filters, and power buses to reduce or minimize noise interference, effectively improve the stability of the power supply, and reduce output ripple. It can be used in many applications such as battery management systems, motor control circuits, clock circuits, and high-frequency region power supplies.

Working Principle

The working principle of aluminum electrolytic capacitor is that, when a DC voltage is applied to the capacitor, it will form an electric double layer at the interface of the two electrodes, the anode and the electrolyte. Due to the different charges on the two sides of the electric double layer, an electric field will be generated between the two sides, which will make the capacitor store energy. The energy storage and the case make the aluminum electrolytic capacitor an ideal component for storing electrical energy in the circuit. The main components of the UTS1H100MDD1TE are aluminum electrolyte, anode and polarized components. The structure is two pieces of flattening support and ears, which plays the role of preventing mechanical vibration and reducing noise.

In the meantime, the anode of the capacitor is an aluminum foil with a large amount of surface area, and a film on the positive electrode is formed by oxidation. It includes a small amount of solid electrolyte, and a large amount of electrolyte is sealed in the capacitor can and soaked with the solid electrolyte. When the aluminum electrolytic capacitor works, the anode and the electrolyte form an opposite electric field. The large amount of electrolyte-filled aluminum foil can increase the capacitor\'s rated capacitance, ideal for applications requiring high capacitance and low internal resistance.

When voltage is added to the capacitor, electrons travel from the anode to the electrolyte, creating a positive charge in the anode, forming an electric double layer on the surface of the anode, and stored energy will accumulate on the surface of the aluminum foil. The greater the voltage applied to the capacitor, the higher the energy stored in the electric double layer, so when the voltage applied to the capacitor is greater than the rated voltage of the capacitor, it can cause damage to the capacitor due to overvoltage or electric leakage. Necessary protective measures need to be taken when using it.

In conclusion, UTS1H100MDD1TE aluminum electrolytic capacitors are mainly used in various electronic circuits of electronic products due to their excellent performance and cost-effectiveness. It can filter the output signal of the power supply, reduce or minimize noise interference, effectively improve the stability of the power supply, and reduce output ripple. Its main components consist of aluminum, anode and electrolyte. When voltage is applied, electrons will travel from the anode to the electrolyte, forming an electric double layer and storing energy on the surface of the aluminum foil.
