Tantalum capacitors are types of electrolytic capacitors known for their relatively small size and high capacitance. They are mostly used in consumer and commercial electronics products, such as cell phones, computers, and digital cameras. An example of a tantalum capacitor is the M39003/01-2992.

Application Field

The M39003/01-2992 is a special type of tantalum capacitor that can be used in high-frequency applications, such as in telecommunications and audio and video systems. It has a small size and a high capacitance, making it ideal for applications where space is limited. In addition, the high capacitance makes it more suitable for high-frequency applications, as it is able to store more energy and discharge it faster. The M39003/01-2992 is also known for its low ESR and ESL values, meaning it is able to provide better stability and effectively reduce noise and distortion.

Working Principle

The M39003/01-2992 is a tantalum capacitor that employs a metal oxide semiconductor (MOS) capacitor structure to achieve its high capacitance. This structure utilizes a thin coating of semiconductor material, usually aluminum oxide, on top a metal oxide film, usually tantalum. This creates a two-layer dielectric structure, which is used to store electrical energy. When a voltage is applied to the capacitor, electrons are attracted to the semiconductor and bond with the metal oxide, forming an electric field which is able to store energy.

In addition, the M39003/01-2992 also utilizes a molded-in fusible resistor to ensure improved electrical performance and reliability. The fusible resistor limits the maximum amount of current that can travel through the capacitor, preventing overvoltage and protecting the capacitor from damage.

Tantalum capacitors, such as the M39003/01-2992, are widely used in consumer and commercial electronics due to their small size, high capacitance, low ESR and ESL values, and excellent reliability. They are ideal for high-frequency applications, such as telecommunications and audio/video systems.
