Working Principle

Tantalum capacitors use a layer of tantalum pentoxide (Ta2O5) as the dielectric material, and are COG/NP0 type capacitors. The dielectric layer is usually very thin, resulting in high leakage current and low parasitic inductance. High capacitance, low ESR/ESL, and excellent reliability make the M39003/03-4080 an optimal choice for certain applications.

Tantalum capacitors are polarized and can only be used in circuits where the correct polarity is indicated. They are typically used in high frequency switching applications. When the capacitor is charged to the voltage level of the input voltage, current flows. The amount of current that can flow through the capacitor is limited by the ESR (Equivalent Series Resistance) of the capacitor. The ESR of a capacitor is determined by the dielectric material, the area of the electrode, and the thickness of the dielectric layer.
