In terms of the TH3B335K020D2700 working principle, it works with the same mechanism as other tantalum capacitors, i.e. with electrochemical double layer (EDL) formation. When a negative voltage is applied to the anode, electrons migrate through the dielectric layer and form a negatively charged EDL at the anode/dielectric interface. As a result, positively charged ions are drawn to the opposite side of the anode, forming another EDL on the cathode side. Consequently, an electric field is established between the two EDLs, resulting in a potential difference across the capacitor and thus providing its desired capacitance.

The EDL formation of the TH3B335K020D2700 allows for a low leakage current, a significant stability, long working life and a wide temperature range. With a maximum capacitance of 0.33F, the TH3B335K020D2700 is one of the best performing surface mount tantalum capacitors available.
