Aluminum Electrolytic Capacitors

The RFS-50V4R7ME3#5 is a type of Aluminum Electrolytic Capacitor, commonly known as an Al-Elec. It is a polarized electrolytic capacitor that is a device offering excellent volumetric efficiency, low equivalent series resistance, wide temperature range and long life. In many applications, these capacitors are the preferred choice of user due to the degree of reliability and performance they offer.

Application Field and Working Principle

Al-Elec capacitors are widely utilized in various electronic circuits due to the high volumetric capability of the device and low equivalent series resistance. In some cases, these capacitors have replaced more traditional devices like tantalum capacitors and ceramic capacitors for their lower cost and high ripple current capabilities. These capacitors are used in filtering operations, to reduce voltage and frequency ripple, in AC/DC power supplies and in power factor correction circuits. They are also frequently used in control panels, automation systems and security systems and are even implemented in some automotive applications.

When voltage is applied to the RFS-50V4R7ME3#5, a chemical reaction takes place at the two leads of the capacitor. This reaction divides the capacitor into two layers of charge carriers that are separated by a porous separator. This separation of charge carriers helps to generate capacitance inside the device. The electrolyte adds to this capacitance because of the electrolytic polarization it provides. The larger the gap between the electrodes of the capacitor, the higher the capacitance that can be produced.

The Aluminum Electrolytic Capacitors are polarized components, meaning that they have a positive and negative pole. With the RFS-50V4R7ME3#5, the negative electrode of the capacitor should be connected to the ground of the circuit and the positive electrode should be connected to the power supply in order to ensure proper operation.

The Al-Elec capacitors possess an exceptionally high operational temperature, high volumetric capability, low-cost and long life. They are also highly efficient in filtering and regulators operations, making them extremely useful in applications where reliability, cost and performance need to be taken into consideration.
