Due to its impressive electrical properties and performance, the 30D105G012BA2A finds a variety of uses in consumer electronics and other industries. In consumer electronics, this device can be used for voltage regulation and surge protection where high ripple currents and stable load performance are required. The device is used in computers, TVs, and cell phones as a DC/DC converter. Additionally, it can be used as a motor start-up filter and signal coupling in circuit board applications, and it is popular in automotive applications such as sensors, power supplies, and motor control systems.

The working principle of the 30D105G012BA2A is based on the electrolytic capacitance of aluminum. The device consists of an anode layer composed of aluminum foil. The anode is immersed in an aqueous electrolytic solution, which acts as an ionic conductor and allows further oxidation of the anode. The dielectric film (consisting of paper and polyester) between the two conductive plates serves as an insulator, and a second aluminum layer (the cathode) is placed on the opposite side of the dielectric film. Together, these components form an anode-cathode-dielectric sandwich, with the electrolyte filling in the gaps.

When a voltage is applied to the electrolytic capacitor, it acts upon the anode layer, causing the anode to oxidize. The electrolytic solution reacts with the anode and a thin layer of oxide is formed. The oxide layer has a dielectric constant much higher than air, causing the electric field around the component to be drastically increased. This allows the capacitance of the device to reach higher values, and thus store energy from the applied voltage.

In summary, the 30D105G012BA2A is a polarized aluminum electrolytic capacitor that is widely used in consumer electronics and other industries. This device is constructed with aluminum foil electrodes and PEN film insulation, and has impressive dielectric properties and reliable performance. The device is used for voltage regulation, surge protection, motor start-up, and more. The capacitance of the device is 105mF, with a voltage rating of 50V, and a working temperature range of 40-90 degrees Celcius. Finally, the working principle of the 30D105G012BA2A is based on the electrolytic capacitance of aluminum which is caused by the reaction between the anode and the electrolytic solution.
