Working Principle

The UUJ1J471MNQ1MS utilizes the aluminum electrolytic capacitor. Aluminum electrolytic capacitors use a chemically formed aluminum oxide (Al2O3) layer as a dielectric. The oxide layer is formed when the anode aluminum foil is passed through an electrolytic solution while receiving a positive charge. Due to the thin oxide layer, aluminum electrolytic capacitors can achieve a large capacitance within a unit volume and also have a long life expectancy if operated within the ratings provided by the manufacturer. The capacitor is typically sealed with either plastic case or can.

The UUJ1J471MNQ1MS capacitor has a capacitance rating of 0.47uF, with a 1000 hour working life at 105ºC. It has a operating temperature range of -25°C to 105°C, maximum voltage rating of 450V, and 10% of tolerance.

In sum, the UUJ1J471MNQ1MS is a high quality aluminum electrolytic capacitor from Eureka, intended for a variety of applications in power supplies, switching power supply and DC power conversion, as well as in other digital circuit designs. It offers high temperature performance, a good long-term reliability and excellent leakage performance.
