Aluminum electrolytic capacitors are a type of capacitor developed in the late nineteenth century. They are constructed using two aluminum plates that are wound around an electrolytic core. One plate is the cathode, while the other is the anode. Between the two plates is a thin, non-conductive dielectric material which separates them. When a voltage is applied to the plates, it causes a current to flow through the electrolyte, which in turn creates a current through the capacitor plates. This current allows for electric charges to be stored and released, which is the basic mechanism of an electric capacitor.

The EKMQ401VSN471MR45S is an aluminum electrolytic capacitor with a high operating temperature, a high dv/dt, and low ESR. These components are mainly used in power supply applications, such as AC/DC power conversion, pulse power supplies and other switching power supplies. The EKMQ401VSN471MR45Scapacitor is also useful for voltage-doubling or voltage-stabilizing applications. Additionally, as a wet slug-type electrolytic capacitor, it is able to reduce common-mode noise in some RF and audio applications.

The operating principle of an EKMQ401VSN471MR45S aluminum electrolytic capacitor is based on the “electrochemical effect”. This means that when a voltage is applied to the plates, the electrolyte reacts with the aluminum plates to form a barrier between them which holds an electrical voltage.

When a voltage is applied, it causes a current to flow in between the plates. This current releases charges from the capacitor plates, which are stored in the electrolyte. When the voltage is removed, those stored charges help to keep the electric charge stored in the big capacitor plates, preventing them from discharging rapidly. This allows for highly efficient energy storage.

The other main application of the EKMQ401VSN471MR45S aluminum electrolytic capacitor is for frequency-sensitive applications. The capacitance value of these types of capacitors is stable over a wide range of frequency, making them ideal for applications such as resonant filters and snubbers.

In conclusion, the EKMQ401VSN471MR45S is a high-performance aluminum electrolytic capacitor, mainly used in power supply applications, voltage-doubling or voltage-stabilizing applications, and frequency-sensitive applications. Its working principle is based on the “electrochemical effect” and is able to provide highly efficient energy storage.
