Aluminum Electrolytic Capacitors

Aluminum electrolytic capacitors are a type of capacitor, which uses electrolysis of aluminum oxide as the main and most effective dielectric layer. The combination of aluminum oxide layer with non-polar electrolyte results in high capacitance values. These capacitors possess several advantages like wide operating temperature range, high-temperature stability, long life, high reliability, low inductance, etc.Aluminum electrolytic capacitors can be divided into three types: axial, radial, and snap-in. An axial type consists of two aluminum foil electrodes, a rolled or pressed paper dielectric, and an aluminum case sealed with a rubberized epoxy. Radial capacitors are constructed, in a similar way, with two aluminum foil electrodes, a pressed paper dielectric, and a rubberized epoxy. Snap-in type consists of two rectangular-shaped aluminum foil electrodes, a rubberized epoxy and an aluminum case.The MALREKV00DC122X00K is an aluminum electrolytic capacitor specifically designed for the switching power supply circuit. The capacitance range of the MALREKV00DC122X00K is from 0.1uF to 22000uF and the rated voltage range is 6.3V to 800V DC. It has an ultra-long life under high ripple current and a wide operating temperature (-40°C to 85°C).The working principle of the MALREKV00DC122X00K lies in the aluminum electrolytic capacitor. A thin layer of oxide over the anode and a non-polar electrolyte layers over the oxide forms a capacitor. When a positive voltage is applied on one of the electrodes (anode), a negative charge moves from the electrolyte and accumulates on the oxide layer. This accumulated negative charge causes an attractive force between the oxide layer and the anode, causing the anode to move towards the electrolyte. As a result, an electrical current is produced.Designed for switching power supply circuit, the MALREKV00DC122X00K is most commonly used for power line bypass capacitor, ripple current suppression capacitor, pulse by-pass capacitor, as well as input-output signal noise filtering. Its wide capacitance range offers designers great flexibility in designing the circuit. Other than industrial application, the MALREKV00DC122X00K is also suitable for vehicular electricals, UPS systems, solar power inverters, aerospace applications, military applications, and medical devices, among other applications. In general, the MALREKV00DC122X00K aluminum electrolytic capacitor provides high capacitance, long life, wide operating temperature range, and low inductance. The combination of these features make it a suitable choice for many applications, including high-reliability, high-voltage applications.
