Tantalum Capacitors

The M39003/03-4022H is a chip tantalum capacitor used in a wide range of applications. Its compact size and low cost makes it an ideal choice for many design projects.

Applications

The M39003/03-4022H is used in many different applications. It is often used in computers, telecom and RF circuits, consumer electronics, battery-operated devices, automotive and military electronics. It can be used for signal filtering, decoupling, and voltage boosting. It is also suitable for applications in the power and telecom industries, such as DC/DC converters, line filtering, and data protection.

Working Principle

The M39003/03-4022H is a chip tantalum capacitor constructed on a ceramic substrate. It has two pins that connect to an internal dielectric, which is the material between electrodes that stores energy as electric charge. The internal dielectric is usually a tantalum pentoxide (Ta2O5) material, typically deposited on the substrate as a film. When the capacitor is connected between two power rails, one positive and one negative, an electric field is created between them. This electric field creates an electric charge on the electrodes that builds up until its potential is equal to the applied voltage. At this point, the capacitor is considered to be fully charged, and any additional voltage applied will be blocked.

Other Features

The M39003/03-4022H is a low-ESR (equivalent series resistance) capacitor, meaning it has low electrical resistance and thus dissipates less power than non-low-ESR capacitors. This makes it suited for applications involving high current and frequency. It is also a solid-state component, meaning it has no moving parts and is more reliable than conventional capacitors. In addition, it is a chip device, meaning it is compact and can be easily soldered in place. Finally, it is RoHS-compliant, meaning it is made from material that complies with the European Union regulation on hazardous substances.

Conclusion

The M39003/03-4022H is a chip tantalum capacitor suitable for all sorts of applications, from consumer electronics to power and telecom. It is a low-ESR capacitor with no moving parts, and it is easy to solder in place. It is also RoHS-compliant, making it a desirable capacitor for almost any application.
