Aluminum electrolytic capacitors are one of the common passive components widely used in various application fields. Its main function is to store electric energy, and they are also used for filtering, coupling, decoupling, bypass, absorption, and other signal noise reduction purposes.The 250PX2.2MEFC6.3X11 aluminum electrolytic capacitor is a product in the SMD series of surface mounted aluminum electrolytic capacitors. It has a nominal capacitance of 2.2μF, a rated voltage of 6.3V, and an operation temperature range of -40°C to 85°C. It has a dimension of 2.5mm x 6.2mm x 11mm, which makes it ideal for small form factor applications.The working principle of an aluminum electrolytic capacitor is based on the electrochemical reaction between two metal plates (anode and cathode) which are separated by an electrolyte. As the anode and cathode are connected to a power source, an electrochemical reaction starts through the electrolyte and the capacitor will charge up. As current flows through the capacitor, electricity is stored in the so-called “dielectric” or “capacitance”. The size of the capacitance depends mainly on the area of the plates and the distance between the plates.The working voltage of an aluminum electrolytic capacitor is determined mainly by the electrolyte used in the capacitor. A low voltage rated capacitor will use a low boiling point electrolyte whereas a high voltage rated capacitor will use a higher boiling point electrolyte. The temperature of an aluminum electrolytic capacitor is limited by its rated voltage. The rated voltage of the 250PX2.2MEFC6.3X11 is 6.3V, which implies that the working temperature of the capacitor should not exceed 85°C.The lifespan of an aluminum electrolytic capacitor mainly depends on the quality of the electrolyte and the physical structure of the capacitor. In general, a higher quality capacitor with a higher electrolyte grade will have a longer lifespan compared to a lower quality capacitor. However, if the capacitor is over-stressed due to exceeding its rated voltage or operating temperature, its life span will be shortened significantly.In conclusion, the 250PX2.2MEFC6.3X11 aluminum electrolytic capacitor is a surface mounted capacitor with a nominal capacitance of 2.2μF, a rated voltage of 6.3V, an operating temperature range of -40°C to 85°C, and a dimension of 2.5mm x 6.2mm x 11mm. It is a low voltage rated capacitor, and its working principle is based on the electrochemical reaction between two metal plates which are separated by an electrolyte. The quality of the electrolyte and the physical structure of the capacitor will determine its lifespan.
