Aluminum electrolytic capacitors have numerous applications in the modern world. For all capacitors, their primary role is to store electric charge between two terminals so that it can be used for resource management. But, aluminum electrolytic capacitors added a layer of complexity to the structure by using oxygen ions, embedded into a “fluxgate” or “zinc alloy” anode, to provide even more storage space. This variety of capacitors, although not used frequently, plays vital roles in automotive, medical and communication systems.

The 400BXW56MEFC16X20 capacitor is one variation of these capacitors. It is a polarized device, meaning that it must be connected correctly to the circuit in order to function properly. The two main types of aluminum electrolytic capacitors include snap-in types, which are radial-leaded, and those with can-terminals. Spacing can be from 3.76mm to 12,765mm, while body size ranges from 4mm x 8mm to 14.269mm x 11.2mm.

In this capacitor, the positive terminal is a metal plate and the negative terminal is a pole stud. The capacitance ranges from 0.05µF to 15,000µF, with voltages from 6.3V to 500V. The structure of the capacitor body is made of a cathode plate, a cathode cap, an anode holding sleeve with insulator, an anode plate assembly, and a sleeve base. The anode holding sleeve with insulator contains an aluminum foil with non-solid electrolyte. This is where the oxygen ions are embedded.

The working principle of this capacitor is very straightforward. A voltage is applied to the positive and negative terminals of the device, which causes the anode and cathode to polarize in absolute opposite directions through electron accumulation or depletion. This creates a space between the cathode and anode, and maintains the barrier. The voltage will determine the size of the electric field which will distinguish the electrons.

The two main advantages that aluminum electrolytic capacitors provide over other types of capacitors are a higher capacitance rating and longer life-span. Since the oxygen ions are embedded in a zinc alloy or fluxgate anode, it is able to store more charge than other capacitors, as it can release more oxygen ions. Its ability to release extra cations further contributes to its longer lifespan.

400BXW56MEFC16X20 aluminum electrolytic capacitors are most notably used in automotive electronic systems, medical devices, and communication systems. Their higher capacitance rating and long life-span make them ideal for tasks such as power supply filtering, power supply buffering, and peak power surge suppression. These capacitors have the ability to store charge for a longer period of time and their relatively low cost makes them an attractive solution for numerous applications.

In conclusion, aluminum electrolytic capacitors are a type of polarized capacitors that use oxygen ions embedded in a “fluxgate” or “zinc alloy” anode for increased storage capacity. The 400BXW56MEFC16X20 capacitor is one example of these capacitors, with positive terminals consisting of a metal plate and negative terminals of a pole stud. This type of capacitor has higher capacitance ratings and longer life spans than traditional capacitors, making it ideal for various automotive, electrical, and medical applications.
