Working Principle of M39003/09-2011/TR

A tantalum capacitor is essentially an energy-storing device. It is composed of two or more metal plates, separated by an insulating dielectric material, typically tantalum pentoxide. These two plates act as a conductor and an insulator which together form a capacitor. When a voltage is applied between the two plates, the dielectric material is polarised and a charge is stored. The magnitude of the charge depends on the capacitance of the device. The ratio of the stored charge to the applied voltage is referred to as the capacitance of the capacitor.

When designing with the M39003/09-2011/TR, the capacitance value of the device is determined by the thickness and area of the plates, as well as the material used as the insulating medium. The ESR of the capacitor is also an important parameter which is directly related to the voltage rating and temperature stability. The ESR of the M39003/09-2011/TR is very low, making it suitable for high powered and high frequency applications.
