Tag: electrolytic capacitor

The full name of tantalum capacitor is tantalum electrolytic capacitor, which is a kind of electrolytic capacitor. It uses tantalum metal as the medium instead of electrolyte as common electrolytic capacitor. In this article, we will introduce what tantalum capacitor is, what advantages tantalum electrolytic capacitor has, and the comparison with ceramic capacitor. Tantalum electrolytic capacitors are a subtype of electrolytic capacitors. They are made of tantalum metal that acts as an anode, covered with an oxide that acts as a dielectric, and surrounded by a conductive cathode.

Nowadays, with the development of economy and society and the improvement of science and technology level, electrolytic capacitors and tantalum capacitors have become more and more popular in the daily life of ordinary people, and they are inside the lamps. But at the same time, many people do not understand the difference between them, and even confuse them. So, let's take a look at the difference between tantalum capacitors and electrolytic capacitors today.

Capacitors are components used to store and hold electric charge. Capacitors are indispensable in circuits. It is divided into many types according to different conditions such as materials and characteristics. Today we will talk about electrolytic capacitors and ceramic capacitors, and briefly introduce the difference between electrolytic capacitors and ceramic capacitors.

Electrolytic capacitor is a kind of capacitor, the metal foil is the positive electrode (aluminum or tantalum), the oxide film (aluminum oxide or tantalum pentoxide) that is close to the positive electrode is the dielectric, and the cathode is made of conductive material, electrolyte (the electrolyte can be liquid or Solid) and other materials together, because the electrolyte is the main part of the cathode, so the electrolytic capacitor is named. At the same time, the positive and negative electrolytic capacitors should not be wrongly connected.

Electrolytic capacitors are capacitors made of an oxide film formed by electrolysis as a medium. The aluminum electrolytic capacitor uses high-purity aluminum as the anode, and a paste composed of ethylene glycol, glycerol, boron and ammonia water as the electrolyte, and electrolysis in the electrolyte produces a very thin layer on the surface of the aluminum. A capacitor made of aluminum oxide film as a dielectric.
