Tantalum Capacitors

Tantalum capacitors are a type of electrolytic capacitor, and they offer some unique features that make them a particularly attractive choice for circuit boards. Much like other electrolytic capacitors, they are made of two metal plated plates, one a tantalum metal, the other a non-metallic dielectric. In a traditional capacitor, two plates are separated by an insulating material. In a tantalum capacitor, one plate is a metal such as tantalum or niobium, and the other plate is made of an electrolyte, usually consisting of manganese dioxide. When either plate is charged, an electric field is created, allowing for the storage of electrical energy. The larger the distance between the plates, the greater the capacitance that can be stored.

The M39003/03-0408H is an example of a tantalum capacitor designed for use on a circuit board. This capacitor type features a 0.08-inch lead spacing, which allows the capacitance to be packed into a much smaller area than is possible with traditional electrolytic capacitors. It also has a much lower leakage current, allowing for more accurate readings and less power loss. Additionally, the tantalum in these capacitors has a very high corrosion resistance that makes it a popular choice for applications in high pH or salty environments.

The main application of M39003/03-0408H is in high-frequency circuits. This capacitor type is particularly useful in circuits due to its low parasitic inductance that allows for higher switching speeds and improved stability in RF circuits. Additionally, this capacitor type is very reliable and has excellent temperature characteristics, making it suitable for use in a variety of temperature-sensitive applications. The capacitor can also be used in audio circuits, providing good damping of high-frequency signals and improved transient response.

The working principle of the M39003/03-0408H is similar to that of other electrolytic capacitors. In this case, the capacitor is made from a manganese dioxide electrolyte sandwiched between two plated plates of tantalum or niobium. When charged, this creates an electric field that stores electrical energy. The capacitance is determined by the distance between the plates, and this distance can be adjusted by changing the plate spacing. As current passes through the plates, it is stored in the capacitor and can be released when the capacitor is discharged.

The M39003/03-0408H is a tantalum capacitor designed for high-frequency applications as well as a variety of other uses. The capacitor is composed of two plates of tantalum or niobium, separated by a manganese dioxide electrolyte. It offers high capacitance in a small area, and also provides excellent temperature and leakage characteristics. The working principle of the capacitor is based on the creation of an electric field between the two plates, which stores electrical energy.
