Working Principle

HES212G400X5L works by storing electric energy between two metal plates. The two metal plates are separated by an electrolyte, usually an aluminium oxide. When a voltage is applied, electrons flow between the plates, which creates an electric field between them. This electric field causes ions to move, creating a current. The current is then stored in the capacitor until the voltage is released.

The capacitor’s capacitance is determined by the size of the plates and the distance between them. The larger the plate area and the smaller the distance between them, the higher the capacitance. The capacitance of HES212G400X5L can range from 1mF to 680mF. The rated working voltage and capacitance must be checked before using the capacitor to ensure it will not be overloaded.

The HES212G400X5L capacitor is an essential component in many electric and electronic devices. It has a wide temperature range and a high capacitance making it ideal for a variety of applications from automotive to military. With its low ESR and ESL, it is able to provide clean and reliable power in even the toughest conditions.
