Tantalum capacitors are an important component in most electronics, and are perfect for applications that require a high capacity in a small, lightweight package. The M39003/01-6183 is a uniquely designed component that combines an impressive range of features to ensure reliable operation in highly-demanding applications. In this article, we’ll take a look at its application field and working principle.

Features

The M39003/01-6183 is a semiconductor-filled aluminum electrolytic capacitor. With capacitance ratings up to 470µF and a wide variety of operating temperatures and voltage ratings, it is suitable for use in many types of high-efficiency power supplies, amplifiers, and other audio/video applications. It features a low ESR of 250mohm, and a low equivalent series resistance of 4mohm. Its high-frequency soft-start feature decrease in-rush current, reducing the risk of thermal stress and component damage. It also features an integral pressure relief screw that allows overpressure relief while operating in overpressure conditions.

Application Field

The M39003/01-6183 is suitable for applications in the audio/video industry, automotive industry, telecommunications, military applications, and other industrial applications. It is specially designed for an operating temperature range of -55ºC to +125ºC, and can handle high temperature variations. It is also suitable for components that require high reliability and long operating life, such as linear and switch-mode power supplies. Its high-end performance also makes it suitable for use in precision amplifiers, active filters, oscillators, and other critical audio/video circuits.

Working Principle

The M39003/01-6183 utilizes both electrolyte and semiconductors to provide an efficient and reliable power storage and release mechanism. Electrically, its operation is relatively simple. When a positive voltage is applied to the electrode, a small amount of electric current flows through the semiconductor layer. This causes a capacitor to form between the two metal plates of the capacitor, which stores the energy. As the voltage increases, more electricity is stored in the capacitor. When the voltage drops, the current is released through the metal plates, leaving the capacitor to discharge.

The semiconductor layer is responsible for its high-end performance as it rapidly disperses excess energy within the capacitor as heat, preventing the capacitor from being damaged due to excessive buildup of heat. This allows the capacitor to operate efficiently under high humidity and temperature extremes. The aluminum electrolytic construction also ensures low ESR and effective performance in high frequency switching applications.

Conclusion

The M39003/01-6183 is a specialized capacitor designed for use in demanding applications requiring high reliability and extended lifetime. Its low ESR, high-frequency soft-start feature, and integrated pressure relief screw allows it to perform well in harsh conditions, and its aluminum construction ensures effective performance in high frequency switching applications. With its wide range of operating temperatures and voltage ratings, it is ideal for use in audio/video, automotive, telecommunications, military, and industrial applications.
