30D126M400EH2A Working Principle

The 30D126M400EH2A aluminum electrolytic capacitor works by storing electrical energy in an electrolyte solution. It consists of two aluminum foils separated by a layer of electrolytic solution. The two aluminum foils act as the plates of the capacitor, and the material between the aluminum foils is the electrolytic solution, which deceives electric charges. When a voltage is applied, electrical current flows, and a charge is stored on the aluminum plates. This charge creates a field between the two plates, which gives the capacitor its capacitance value. The larger this field, the higher the capacitance value. The electrolyte solution is also an insulator, so the charge is trapped between the plates until the disconnection of the capacitor.

The 30D126M400EH2A has a wide capacitance range of 0.7 μF to 2200 μF, and a wide operating temperature range of -55°C to +105°C. It is also highly stable at high temperatures and offers high ripple current and low equivalent series resistance (ESR) behavior. The ESR of the capacitor determines how well it can handle high current and determines its life expectancy.

The 30D126M400EH2A aluminum electrolytic capacitor is a reliable and versatile energy storage component that can be used in a variety of applications. It offers a great balance between its capacitance, temperature and voltage. Its wide capacitance range, low ESR, and temperature stability make it ideal for many DC power supply, audio and power system applications.
