Aluminum electrolytic capacitors, popularly known as “Alcos”, are power electronic components used in industry-level electronic equipment. They are one of the most commonly used capacitor types because of their robust construction and wide availability. Alcos are used in a variety of applications such as power supplies, instrumentation, motors, and HVAC systems. URS2D470MHD is one example of an Alco designed for high voltage and high temperature applications. This article will discuss the application field and working principle of URS2D470MHD.

Application Field of URS2D470MHD

The URS2D470MHD is designed for use in high voltage power supplies and high temperature operating environments. It has an ESR rating of 25 mΩ and a maximum operating voltage of up to 400V DC, making it an ideal choice for high-power applications. In addition, the capacitor also features an operating temperature range of -55°C to +125°C and an insulation resistance of up to 1011Ω, providing superior protection from electrical leakage in high temperature environments. The product also boasts a high ripple current rating of up to 5.07A and a capacitance range of 470 μF to 10,000 μF.

Working Principle of URS2D470MHD

The URS2D470MHD is an aluminum electrolytic capacitor which has a dielectric composed of aluminum and a solid electrolyte. When a voltage is applied across the terminals of the capacitor, the positively charged ions in the electrolyte pass through the dielectric and deposit metal onto the surface of the capacitor plates, creating a conductive path. This phenomenon is known as electrolysis. Current is then able to flow between the capacitor plates, creating an electric field. This electric field generates a capacitance, allowing the capacitor to store electrical energy.

The URS2D470MHD is designed to be self-healing. This means that if the amount of current applied to the capacitor rises above the maximum specified limit, the excess current will be discharged through the electrolyte. This prevents the capacitor from being damaged by high current levels and ensures the capacitor\'s long-term reliability. The product is also designed to meet UL, RoHS, and CE safety standards.

In conclusion, the URS2D470MHD is an aluminum electrolytic capacitor designed for high voltage and high temperature applications. It has an ESR rating of 25 mΩ, a maximum operating voltage of up to 400V DC, an insulation resistance of up to 1011Ω, and a ripple current rating of up to 5.07A. The capacitor is self-healing and meets UL, RoHS, and CE safety standards, making it an ideal choice for high-power applications.
