Aluminum Electrolytic CapacitorsAluminum electrolytic capacitors are a type of electrochemical capacitor that experience change in capacitance over operating temperature. They are composed of two aluminum foil electrodes, called anodes and cathodes, which are separated by a thin insulating material, typically impregnated with oil. The anode is electrically connected to a housing and/or the capacitor\'s external terminals and is the negatively charged element of the capacitor. The cathode has a positive charge and is connected to a saucer-shaped conductive metal back plate, which acts as the counter electrode, where the oppositely charged ions gather. The construction of an aluminum electrolytic capacitor is similar to that of a conventional electrolytic capacitor, however, the electrolyte is an ionic conductor (an electrolyte).In general, an EKMR451VSN471MR50S aluminum electrolytic capacitor is constructed in the same way as other electrolytic capacitors but with thicker and longer anode and cathode fingers. This improves the stability and reliability of these parts, while allowing them to store more energy. These capacitors have an extended voltage range which allows them to be used in a variety of applications. They also have a low ESR, making them well suited for use in switching power supplies and energy storage for PC motherboard power supplies.The working principle of the EKMR451VSN471MR50S aluminum electrolytic capacitor is based on a chemical reaction known as the electrolysis of water. During this reaction, positively charged metal ions interact with the negatively charged anode and transfer the positive charge to the cathode. As the positive charge accumulates at the anode, a reverse current flows from the anode to the cathode. This reverse current creates a voltage across the capacitor which can store energy. This electrolytic capacitor has a working voltage of 450v and can store up to 4.71mV of energy. Its temperature range is from -40°C to 105°C. This makes the EKMR451VSN471MR50S aluminum electrolytic capacitor suitable for a variety of applications such as DC-DC converters, HVAC power supplies, UPS systems, power supplies, motor drives and LED lighting ballasts.The EKMR451VSN471MR50S aluminum electrolytic capacitor is also widely used in consumer electronics due to its low ESR. Its low ESR allows it to effectively filter high frequency noises, eliminating the need for additional filter capacitors. This makes it ideal for use in laptop, smartphone and tablet chargers. Additionally, its high working voltage and extended temperature range make it a popular choice for automotive applications such as fuel pump and ABS systems.In conclusion, the EKMR451VSN471MR50S aluminum electrolytic capacitor is a high-performance component designed to store energy and filter high frequency noises. It is well suited for a variety of applications such as HVAC, motor drives, consumer electronics and automotive electronics.
