The UUN1H470MNQ1MS is used in a variety of applications, such as microelectronic circuits, sensors, switches and filters. It is especially suitable for high frequency applications, as it has a low ESR value (2.1mΩ max). It is also suitable for a wide range of temperature ranges, which makes it suitable for use in automotive, defense, and avionics applications. In addition, the UUN1H470MNQ1MS capacitor is RoHS compliant, which allows it to be used in lead-free designs.

The working principle of the UUN1H470MNQ1MS aluminum electrolytic capacitor is based on Faraday’s Law. This law states that when two metal plates are placed facing each other in an electrolyte solution, a voltage is applied across the plates and the electrical energy stored in the form of an electric field. The stored electric field constitutes a capacitor. The capacitance of a capacitor is primarily determined by the physical properties of the reacting system, such as electrode size and material, electrolyte, etc. In the case of the UUN1H470MNQ1MS aluminum electrolytic capacitor, the electrodes are aluminum foil, which is formed into a basket shape. The foil is then covered with an electrolyte system, which is typically composed of a resin and liquid electrolyte. When a voltage is applied, the electrolyte solution migrates around the aluminum plates, forming a dielectric layer between the plates. This dielectric layer increases with voltage, increasing the capacitance value of the capacitor.

The UUN1H470MNQ1MS aluminum electrolytic capacitor is a robust and reliable component suitable for a variety of high frequency applications. It has a wide temperature range, making it suitable for automotive, defense, and avionics use. In addition, its low ESR value makes it suitable for high frequency applications. Its working principle is based on Faraday’s Law, and its capacitance is determined by the physical properties of the reactants. The UUN1H470MNQ1MS is RoHS compliant, allowing it to be used for lead-free designs.
