Aluminum electrolytic capacitors, designed for high-power applications, refer to devices utilizing electrically polarized aluminum oxide as dielectric material. The USR1E330MDD1TE capacitor is one such device. It features high energy density, low equivalent series resistance, high ripple current storage capacity, and long expected service life. These features make it particularly suitable for applications in storing and smoothing high power pulses such as laser diode drivers and high-speed switching power supplies.

The USR1E330MDD1TE consists of an anodized aluminum internal electrode, an external electrode with an insulated external terminal to form the inner structure of the capacitor. It also includes an electrolytic solution with a specific composition, an insulating sealing gasket, and an outer decorative sleeve which serves both for safety and aesthetics. This internal structure creates an electric double layer of ions which act as a capacitor and store electrical energy. When an electrical current is applied across the capacitor’s terminal, electric charges are distributed and stored within the aluminum oxide. These stored electric charges provide a stable electrical potential across the capacitor. When the capacitor is discharged, the stored charges are released and the capacitor can be used again.

Because of its high ripple current storage capacity and low equivalent series resistance, the USR1E330MDD1TE is well suited for applications that require both low ESR and high ripple current storage capabilities, such as switching power supplies, laser diode drivers, motor drives, and power supply lines. It features high-frequency response performance, along with excellent insulation resistance and high surge current capability for high-power applications.

The USR1E330MDD1TE is designed to be durable and reliable under temperature extremes from -40°C to +105°C. Thanks to its construction and robust components, it is resistant to shock, vibration and moisture, enabling it to operate in harsh conditions and with extended life expectancy. This makes the USR1E330MDD1TE a suitable capacitor for high power applications.
