Aluminum electrolytic capacitors make up the largest class of capacitors and the most widely used type of electrolytic capacitor due to their low cost, high energy density, and wide range of temperature ratings. In this article, we will discuss the UCZ2A301MNQ1MS application field and working principle of aluminum electrolytic capacitors.

The UCZ2A301MNQ1MS is an extremely high-temperature rated aluminum electrolytic capacitor featuring an axial-leaded polycarbonate case, with a negative electrode insulated with polyester tape. The UCZ2A301MNQ1MS is designed for operating temperatures of up to 150°C and 85°C case temperature. This capacitor is suitable for use in high-temperature industrial applications such as welding equipment and HVAC system controllers.

The working principle of an aluminum electrolytic capacitor is similar to that of a regular capacitor. The main difference is that the construction of an aluminum electrolytic capacitor allows for a much higher capacitance compared to a regular capacitor, as the materials it is constructed from are much better conductors of electricity. The construction is also different, as the aluminum electrolytic capacitor consists of two aluminum foils, with insulating oxide layers and impregnated paper separators, that are enclosed in a casing. The oxide layers act as the capacitor’s dielectric, and the impregnated paper separators act as the capacitor’s electrodes. The amount of charge a capacitor can store is related to the size of the dielectric, with the larger dielectric having more charge storage capacity than a small dielectric.

Due to the high capacitance of aluminum electrolytic capacitors and the large amount of current they can handle, they are often used in applications that require high current and/or high voltage. Examples of these applications include power supply unit smoothing, DC smoothing, memory and microcomputer equipment, power supplies, switching power supply filtering, LCD bias current, and peripheral circuit input and output filtering.

The UCZ2A301MNQ1MS aluminum electrolytic capacitor is designed to operate with a continuous ripple current of up to 2.1A and a peak current of 4.6A. The capacitor’s operating temperature range is -55°C to +150°C and its case temperature range is -40°C to +85°C. The capacitor has a capacitance of 300mF, a voltage rating of 10V and a tolerance of ±20%.

The UCZ2A301MNQ1MS aluminum electrolytic capacitor is a great choice for high-temperature, high-current applications that require a rugged, reliable capacitor. It offers excellent performance, long life, and low ESR, making it suitable for most any application that requires high performance. With its wide operating temperature range, it is an ideal choice for applications such as welding equipment, HVAC systems, or any other application that requires high current or high voltages.
