Tantalum Capacitors – M39003/01-2384/TR Application Field and Working Principle

Tantalum Capacitors are capacitors that use a tantalum metal as one of their components. This type of capacitor has many advantages, such as being lightweight, having a low profile, offering high stability, and having an extremely low ESR (Equivalent Series Resistance) and long shelf life. The enabling technology for these capacitors is the electrochemical process of producing a conducting oxide layer, usually tantalum pentoxide.

In terms of applications, the M39003/01-2384/TR capacitor is ideal for use in power conversion applications due to its high capacitance tolerance, excellent volumetric efficiency, and long lifetime. It is also a reliable capacitor for high-speed signal processing applications as it has low ESR values and stable electrical characteristics over temperature.

The M39003/01-2384/TR capacitor is usually constructed using two conductive plates, between which is a dielectric material. The construction of the capacitor determines the type and performance of the capacitor. The plates are usually cylindrical, made out of aluminum foil for tantalum electrolytic capacitors. The dielectric material is usually either tantalum powder or barium titanate for electrolytic capacitors.

The working principle of tantalum capacitors is based on the phenomenon of electrical charge storage and release. When electric charge is applied, it accumulates and is stored on the lead plates and in the intervening dielectric material. This phenomenon is called capacitance. Whenever there is a change in the voltage that is applied, the capacitance will also change accordingly, allowing electrical energy to be transferred from one medium to another.

When electric current is applied to the tantalum capacitor, it will heat up due to the resistance of the dielectric layer. This is known as dissipation factor, and it is one of the main indicators of the performance of a tantalum capacitor. The dissipation factor, along with other factors such as capacitance, ESR and voltage-coefficient, determines the parameters of the capacitor performance.

The capacitance of a tantalum capacitor is determined by its physical construction. The capacitance is usually expressed in Farads. The ESR of the capacitors determines the amount of current that can be applied before the capacitor starts to heat up, known as the ripple current. The voltage-coefficient determines the capacitance under various voltages and is expressed in percentage per volt. The dissipation factor rating indicates the performance of the capacitor in terms of amount of energy dissipated. All of these factors combined determine the performance of a tantalum capacitor.

In summary, the M39003/01-2384/TR tantalum capacitor is a reliable, low-profile capacitor with excellent performance characteristics. It offers extended temperature range, long shelf life and excellent high frequency performance. The capacitor is ideal for use in power conversion applications due to its high capacitance tolerance, excellent volumetric efficiency, and long lifetime. The working principle of this type of capacitor is based on the phenomenon of electrical charge storage and release.
