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 .
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.
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). Exceptions occur for imperial in the two smallest rectangular passive sizes. The metric codes still represent the dimensions in mm, even though the imperial size codes are no longer aligned.
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:
