The DLE-201U-15A is a type of Ferrocore, which is an energy-storage device similar to a capacitor, but designed to store more energy in a much smaller package. It is composed of an iron core (made of iron powder) and an insulating shell, which are internally connected by an insulating medium. The DLE-201U-15A has a voltage rating of up to 15V, and a capacitive rating of up to 180Wh/l. It provides superior energy storage performance compared to traditional capacitors, and has a high charge/discharge cycling performance. This part will find applications in automotive and industrial systems, such as high-power inverters, DC-DC converters, and UPS systems.
