Tantalum Capacitors

Tantalum capacitors are widely used in a variety of applications due to their high stability, small size and large capacitance. The M39006/25-0198H is a type of tantalum capacitor that is particularly useful in industrial and aerospace applications. This article will discuss the application field and working principle of M39006/25-0198H.

Application Field

The M39006/25-0198H is an axial-leaded tantalum capacitor with a voltage rating of 16 volts and a capacitance of 20 μF. This type of capacitor is well-suited to military and aerospace use, because of its high reliability and stability. It is also widely used in commercial products and industrial applications.

The M39006/25-0198H is constructed using a tantalum anode and a tantalum pentoxide dielectric. It is then housed in a metallized case for protection and electrical shielding. The case is sealed with an epoxy resin to protect against environmental contaminants, such as dust and moisture.

The M39006/25-0198H is designed to operate in temperatures ranging from -55°C to +125°C. It has a maximum operating voltage of 16 volts and a saturation current of 0.25 mA. The capacitor also has a very low internal resistance of 0.75 Ohms, which makes it highly efficient.

Working Principle

The working principle of the M39006/25-0198H involves the use of an anode and dielectric. A voltage applied to the anode causes a chemical reaction between the anode and dielectric, which leads to the accumulation of positive charges on the anode. This allows the capacitor to store an electric charge.

The dielectric material used in the M39006/25-0198H is a tantalum pentoxide, which has a uniquely high dielectric constant. This means that less electrical energy is needed to store charge in the capacitor. The high dielectric constant also contributes to the high levels of reliability and stability associated with this type of capacitor.

When voltage is applied to the M39006/25-0198H, the positively charged anode attracts and stores negative electric charge from the external circuit. This electric charge is stores in the capacitor and can be released when the voltage is reversed. Thus, the capacitor can act as a source of voltage, or as a buffer to store energy when power is disconnected.

Conclusion

The M39006/25-0198H is an axial-leaded tantalum capacitor designed for military and aerospace applications. It has a highly stable and reliable design, and it can operate in a wide range of temperatures. The working principle of the M39006/25-0198H involves the use of an anode and dielectric material, which allows it to store electric charge. This makes the capacitor an ideal choice for applications that require reliable and consistent power.
