UCY2G470MHD3

Aluminum electrolytic capacitors are widely used components in the electronics industry. They are typically used to smooth power supply voltages, as filters or in power supply bypass applications. The UCY2G470MHD3 is one such device, designed for use in lead-acid battery applications.

This specific device has a voltage rating of 400V and a capacitance of 470µF. Its maximum ripple current is 13A while the operating temperature range is -40°C to 85°C. It is a radial type device that features a sealed design to ensure reliability and performance.

The UCY2G470MHD3 features radial leads and utilizes reliable, low leakage aluminum electrolytic capacitors. This helps to reduce the series inductance of the device and extends its operational stability. It also features a sealed design that prevents the capacitor from leaking, which has the added benefit of preventing hazardous shocks.

The working principle of aluminum electrolytic capacitors is based on the electrolytic action of ions in the electrolyte solution, which is typically an aqueous mixture of sulfuric acid and water. An electric field is applied across the device, causing cations in the electrolyte to migrate towards the anode and anions towards the cathode. As a result, an electric double layer forms where the cations and anions meet. This double layer acts as a capacitor and it is this charge separation that creates the capacitance of the device.

The key advantage of electrolytic capacitors in general is their ability to store and maintain a charge. This energy stored in the capacitor can be released rapidly for short bursts of power, which makes them well-suited for high-current applications such as powering motors or starting engines. Their larger size compared to other types of capacitors also allows the use of higher capacitances, making them suitable for filtering applications.

In summary, the UCY2G470MHD3 is a reliable and robust aluminum electrolytic capacitor, designed for use in lead-acid battery applications. Its sealed design, low series inductance and high ripple current make it ideal for such applications. Its large capacitance and stable performance also make it suitable for power supply smoothing and filtering applications.
