Tantalum Capacitors

Tantalum capacitors, also known as Ta capacitors, are a type of electrolytic capacitor. They are used in electronic circuits to store charge and energy. Tantalum capacitors are constructed from a tantalum powder containing an electrolyte, which serves as the dielectric material. The material is then compressed and inserted into a metal sleeve or case, creating the capacitor. The metal sleeve or case acts as the negative terminal, while the tantalum powder acts as the positive terminal.

Working principle of M39003/03-4085H

The working principle of the M39003/03-4085H is based on the principles of electrochemistry. When an electric voltage is applied to the capacitor, it causes a chemical reaction between the tantalum powder and the electrolyte. This reaction releases electrons and as a result, a charge is created on each end of the capacitor. The amount of charge created is proportional to the voltage applied. The charges on the capacitor create an electric field, which is how the capacitor stores energy.

The capacitor also has an internal resistance known as its ESR (Equivalent Series Resistance). When a voltage is applied to the capacitor, some of it is lost due to the ESR, resulting in a voltage drop across the capacitor. The ESR also affects the capacitor’s ability to discharge quickly. The lower the ESR, the faster the capacitor will be able to discharge.

The M39003/03-4085H is a reliable and versatile capacitor. It is widely used in a variety of applications due to its low ESR, wide operating temperature range, and its small package size. Its versatility makes it an ideal capacitor for many different applications.
