Aluminum Electrolytic Capacitors

An aluminum electrolytic capacitor is a type of capacitor that is especially suitable for use in an alternating current (AC) or high-frequency circuit. It is characterized by a very high capacitance compared to other capacitor types for the same volume, and this makes them ideal for applications requiring very high-energy storage.

The UVR1H102MHD, in this particular series, is a radial leaded aluminum electrolytic capacitor manufactured by United Chemi-con Corporation. It is an automotive grade capacitor, specifically designed for the requirements of the car audio industry. The UVR1H102MHD is a popular capacitor choice, due to its ability to handle large peak currents with low losses, and its excellent stability and reliability.

The UVR1H102MHD has a voltage rating of 5 VDC, with a capacitance of 1,000µF and a temperature range of -25°C to +85°C. In terms of size, the capacitor has a diameter of 12.5mm and a length of 20mm. The UVR1H102MHD is a polarized capacitor, meaning it requires an external bias voltage to charge its internal plates, and the negative pin should always be connected to the negative bias supply.

The working principle of the UVR1H102MHD is based on the electrochemical properties of aluminum electrolytic capacitors. The capacitor is composed of two plates, one of aluminum foil and one of a wet electrolyte. When voltage is applied, a chemical reaction takes place inside the capacitor that charges the capacitor. The greater the voltage, the larger the amount of charge stored in the capacitor.

The plates of the capacitor are separated by the electrolyte, and when voltage is applied, ions flow between the plates, creating a charge. The amount of charge stored in the capacitor is determined by the voltage applied and the current supplied, and this is referred to as capacitance. The capacitance of the UVR1H102MHD is 1,000µF, which means it can hold 1,000µF of charge.

The UVR1H102MHD is best suited for applications requiring high current with low losses, such as car audio systems, as well as power supplies and circuits with high-frequency switching. The capacitor has low ESR (Equivalent Series Resistance), making it well-suited for applications requiring large amounts of energy storage and low resistance. The capacitor also offers excellent reliability and stability, so it is suitable for use in systems that require reliability and accuracy.

In summary, the UVR1H102MHD is an aluminum electrolytic capacitor manufactured by United Chemi-con Corporation. It is a radial leaded capacitor, with a voltage rating of 5 VDC, and a capacitance of 1,000µF. It is designed for high current applications with low losses, such as car audio systems, as well as power supplies and circuits with high-frequency switching. The capacitor utilizes the electrochemical properties of aluminum electrolytic capacitors for its working principle, and is characterized by its low ESR and excellent reliability and accuracy.
