Tantalum Capacitors

M39003/03-2037/TR Application Field and Working Principle

Tantalum capacitors are used in many different types of electronic circuits such as computer systems, mobile phones, and other industrial components. These capacitors are widely used due to their high stability, low series inductance, and low self-discharge rate. The M39003/03-2037/TR particular type of tantalum capacitors is often used in applications requiring greater capacitance than conventional tantalum capacitors, such as switching regulators, power supplies, and audio-frequency circuits.

Tantalum capacitors are formed by forming a solid layer of a metal oxide on the surface of a tantalum wire, which acts as the cathode of the capacitor. On the anode, a suitable electrolyte is used. The thin metal oxide layer acts as the dielectric, while the electrolyte serves as a conducting medium for the charge carrier. These two components form a capacitance. By changing the voltage across the plates of the capacitor, an electric charge is stored in the dielectric layer, resulting in a capacitance.

This capacitance can be controlled by the voltage applied to the anode, and the size of the oxide layer. When the voltage is less than the breakdown voltage of the oxide layer, the capacitor charges quickly, and the capacitance decreases correspondingly. When the voltage is greater than the breakdown voltage of the oxide layer, the capacitor does not charge and the capacitance remains at its initial value. This breakdown voltage is usually between 2 and 3 volts for the type of tantalum capacitor used in the M39003/03-2037/TR application.

Tantalum capacitors, due to their high capacitance values, are useful for many applications, such as power supplies, switching regulators, audio-frequency circuits, and other electronic systems. Furthermore, these capacitors are highly reliable and offer an excellent price/performance ratio.

Due to their wide range of applications and excellent performance, the M39003/03-2037/TR type of tantalum capacitors is often used in many different markets, such as automotive, consumer, medical, industrial, and aerospace. This type of capacitor offers an ideal solution for many applications.
