397LBB250M2DC

Aluminum Electrolytic Capacitors are capacitors that contain an anode of aluminum foil with an oxide layer that acts as the dielectric that is formed in a chemical reaction process of oxidation when combined with an electrolyte. These capacitors are often used in consumer electronics such as computers, televisions, cameras, and phones. The particular capacitance of aluminum electrolytic capacitors can range from 1.0μF to over 500,000μF and their voltage rating can range from 10 volts (V) to several thousand volts (V). The application of the particular capacitor, the 397LBB250M2DC, is in the automotive electronics industry.

The 397LBB250M2DC aluminum electrolytic capacitor is a low-impedance, high-wattage device with a voltage rating of 250V. This capacitor has a 397mm (15.6”) lead length and a power rating of 2,000 watts (W). The rated frequency is 25kHz and the rated current is 50 amps. The capacitance of the 397LBB250M2DC is determined based on the desired application. Generally, capacitance values range from 2.2µF to 1,000 µF.

The working principle of the aluminum electrolytic capacitor is based on the interaction of two surfaces that are separated by an insulator, such as the oxide layer. When a voltage is applied across the capacitor, electrons from the negative terminal migrate to the anode while electrons from the positive terminal migrate to the cathode. This results in a movement of electrical charge from one plate to the other through the electrolyte, which increases the capacitance. The electric charge on both plates is equal and the capacitor is said to be in a "charged" condition. When the voltage is removed, the electric charge on the plates is reversed, allowing the capacitance to return to zero.

The 397LBB250M2DC capacitor is used in automotive and other vehicle-based applications. The capacitor is used to power an array of various electrical components, including lights, radio, and other electronic equipment. The capacitor also functions as a buffer, storing energy to help stabilize the power supply during brief fluctuations. The 397LBB250M2DC aluminum electrolytic capacitor is best suited for applications where a low impedance, high wattage, and high-voltage rating are required.

Overall, the 397LBB250M2DC aluminum electrolytic capacitor is a versatile and reliable device that is designed to meet the high-voltage, high-wattage requirements of automotive and other vehicle-based applications. The capacitor is widely used across the industry and is known for its low impedance, high wattage, and long life properties. The working principle of this device is based on the interaction of two surfaces that are separated by an insulator, such as the oxide layer, resulting in a movement of electrical charge from one plate to the other through the electrolyte.
