Tantalum capacitors in different styles: axial, radial and SMD-chip versions (size comparison with a match) 10 μF 30 VDC-rated tantalum capacitors, solid electrolyte epoxy-dipped style. A tantalum electrolytic capacitor is an electrolytic capacitor , a passive component of electronic circuits .
The codes given in the chart below usually tell the length and width of the components in tenths of millimeters or hundredths of inches. For example, a metric 2520 component is 2.5 mm by 2.0 mm which corresponds roughly to 0.10 inches by 0.08 inches (hence, imperial size is 1008).
Polymer tantalum electrolytic capacitors have ESR values that are approximately only 1/10 of the value of tantalum electrolytic capacitors with manganese dioxide electrolyte of the same size. By a multi-anode technique in which several anode blocks are connected in parallel in one case, the ESR value can be reduced again.
Aluminum, tantalum and niobium electrolytic capacitors are named after the material used as the anode and the construction of the cathode (electrolyte) Polymer capacitors are aluminum, tantalum or niobium electrolytic capacitors with conductive polymer as electrolyte; Supercapacitor is the family name for:
Description: Diagram comparing construction of three types of capacitors: electrostatic (normal), electrolytic (high capacity) and electrochemical (supercapacitors).

A real world model of an electrolytic capacitor. Shows the capacitor (C), the dieletric leakage resistance (R leakage), and the effective series resitance and inductance (R ESR and L ESL). Date: 25 November 2006: Source: Own drawing
These first sintered tantalum capacitors used a non-solid electrolyte, which does not fit the concept of solid electronics. In 1952 a targeted search at Bell Labs by D. A. McLean and F. S. Power for a solid electrolyte led to the invention of manganese dioxide as a solid electrolyte for a sintered tantalum capacitor. [23]
