Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors (also known as electrolytic capacitors) are one of the most widely used components in electronics today. They are used in almost all types of electronic designs and are an essential part of any electronic device.The EKXL451ELL390MJ40S is an aluminum electrolytic capacitor with a 40mm diameter body and a tall, snap-in lead configuration. It has a maximum voltage rating of 400V and a standard capacitance range of 9μF to 390μF at 100 to 85°C respectively. This capacitor is typically used in AC line input filter applications and is designed for use in both AC and DC circuits.An aluminum electrolytic capacitor is composed of a metal case of aluminum, multiple layers of aluminum foil separated by layers of paper, and a charge-storing electrolyte. A cathode terminal is connected to one of the metal foils and an anode terminal is connected to the other in order to create a “capacitor.”When constructing aluminum electrolytic capacitors, the foil is rolled and wrapped in paper and inserted into a cylindrical shell made of aluminum. The aluminum is then subjected to special processes to create its porous structure. To further enhance its mechanical strong properties, a plastic sealing is applied on the outside of the aluminum shell. The electrolyte is then injected into the device via a special port and the lead wires are then connected to the device’s terminals. When an AC or DC voltage is applied across the terminals, the aluminum will begin to dissolve and react with the electrolyte. As a result, a layer of oxide will form on the surfaces of the aluminum foil electrodes and will create a barrier which will prevent further reaction of the electrolyte with the aluminum. This oxide layer will also store electric charges which will increase the capacitance of the device.The purpose of using an aluminum electrolytic capacitor is to even out the signal output of an electronic circuit. In other words, capacitors help reduce the amount of voltage ripple or “noise” in a circuit. They are also used in power supply circuits to filter and limit current and prevent circuits from overloading. The EKXL451ELL390MJ40S can be used in a variety of applications such as audio pre-amps, power supplies, and line filters. Its long lead design makes it ideal for use in applications where components need to be mounted in tight spaces or in locations where external connection points are not readily accessible. Overall, the EKXL451ELL390MJ40S is a reliable, cost-effective capacitor that can be used in a variety of applications. It’s snap-in lead design makes it easy to install and its long life and high operating temperature range gives it great reliability. With its high capacitance and voltage ratings, it’s perfect for use in almost any application.
