Aluminum Electrolytic Capacitors
Aluminum electrolytic capacitors are one of the most commonly used capacitors in the field of electronics and electrical engineering. These capacitors are typically made of an aluminum can, an electrolyte (usually an organic solution or KOH), a wound aluminum foil called an anode, an aluminum oxide insulator, and various terminals. To understand the operation and application field of the ALS70A912NP400 aluminum electrolytic capacitors, it is necessary to understand the general working principle of the capacitor.
Working Principle
At its most basic level, an aluminum electrolytic capacitor is a two-terminal device used to store energy in an electric field. It typically consists of two metal plates arranged parallel to each other with a non-conductive material (electrolyte) between them. When a voltage is applied to the capacitor terminals, the electric field created by the potential difference between the two plates causes an electric current to flow between them. This current sets up another electric field that is opposite in sign to the first, which in turn reduces the amount of charge that needs to be carried across the plates.
The amount of charge that can be stored in an aluminum electrolytic capacitor is proportional to its capacitance, which is determined by the geometrical characteristics of the plates. Generally, aluminum electrolytic capacitors have large capacitance values, with values ranging from the low picofarad levels to the thousands-(or even millions-) of-microfarad range. These capacitors also feature relatively high voltage ratings and low ESR (equivalent series resistance).
