Aluminum electrolytic capacitors are passive electronic components that allow current to pass in one direction while blocking current in the opposite direction, and are the most commonly used capacitors today. The UML1H010MDD is a type of aluminum electrolytic capacitor designed specifically for applications such as low-frequency power conversion, differential mode noise suppression, switching power supply smoothing, and DC-DC converters. These applications rely heavily upon the capacitor’s ability to store energy and quickly release it into the circuit when needed.

In terms of construction, aluminum electrolytic capacitors differ from the more common ceramic capacitors in that they are two-terminal, cylindrical aluminum cans which are sealed at one end and hold an electrolyte solution inside. A pair of aluminum foils and a separator material form the capacitor plates. An anode foil is etched to create a very large surface area for maximum capacitance, and the cathode foil is flat. The separator material, typically paper or plastic, serves to keep the plates from touching and creating a short circuit.

When a voltage is applied in a forward direction across the capacitor’s two leads, the electrolyte solution allows an electric current to flow through the capacitor, creating a positive charge on the anode side and a negative charge on the cathode side. This charge is stored in the capacitor’s capacitance and can be used in various applications. When the capacitor is charged, the higher voltage on the anode causes electrons to flow from the cathode side to the anode side, creating an electric field between the plates. This electric field exerts a repulsive force on the ions in the electrolyte solution, preventing them from flowing back from the anode to the cathode, thus holding the charge in the capacitor.

The UML1H010MDD is an aluminum electrolytic capacitor that has a rated voltage of 10VDC and a capacitance of 10µF, making it ideal for low-frequency power conversion, power supply smoothing, and DC-DC converters. It has an ESR (Equivalent Series Resistance) rating of 15mΩ, a ripple current rating of 62mA at 120Hz at 25°C, a rated temperature of 125°C, and a rated lifetime of 2000 hours at 25°C. Its small size, low price, and long service life make it a popular choice for space-constrained electronics.

In summary, the UML1H010MDD is an aluminum electrolytic capacitor that is designed for applications such as power conversion, power supply smoothing, and DC-DC converters. Its two-terminal, cylindrical construction allows it to store and quickly release a charge of electricity into the circuit when needed, and its ESR and ripple current ratings make it suitable for these types of applications. It offers long service life, small size, and affordability, and is a popular choice for space-constrained electronics.
