Tantalum capacitors are small, high-capacity, and low-voltage capacitors typically used at the hearts of electronic circuits, often when mounted directly onto integrated circuits (ICs). The M39003/01-6382H is a surface mount, wet tantalum capacitor made by KEMET, one of the leading global manufacturers of capacitor technology solutions. This particular capacitor is a purpose-built solution optimized for 3.3 V DC supply voltages and provides a high capacitance of 2.2 uF within a unified package.

The M39003/01-6382H is typically used to reduce system power consumption, minimize power dissipation, improve EMI attenuation, and reduce circuit board complexity and part count. Its use is widespread across numerous industries and applications, from automotive cabin electronics systems to medical equipment, consumer products, and more.

In terms of working principle, the capacitor employs two distinct surfaces that are separated by an insulating dielectric layer. This layer acts as an insulator by electrically isolating the two elements, allowing electric current to flow only through them when a potential difference has been applied between them. When a potential difference is applied, the capacitor stores charge in the form of an electric field. The size of the electric field is determined by the applied voltage, the amount of charge that is stored, and the characteristics of the dielectric layer. As the charge builds up, the capacitor acts like an inductor, storing energy and providing a unique set of characteristics to electronic circuits.

In addition, tantalum capacitors have certain characteristics that make them especially useful in many applications. Their internal construction gives them good leakage rates and excellent reliability compared to other types of capacitors. They are also small in size, making them ideal for use in compact designs. Additionally, their low equivalent series inductance (ESL) and equivalent series resistance (ESR) reduce power loss and ripple current, which is particularly beneficial when used in switching power supplies.

In sum, the M39003/01-6382H is a high-capacity wet tantalum surface mount capacitor that is used in a variety of applications to reduce system power consumption, minimize power dissipation, improve EMI attenuation, and reduce circuit board complexity and part count. Its construction and features render it especially useful in supplying high-current applications such as DC-DC converters, switching power supplies, and decoupling in modern communications and computing applications.
