Mar 29, 2017· By Richard Wilson 29th March 2017. There is now an alternative to solid tantalum capacitors. Recent advances in polymer-cathode technology and improvements in tightening the tantalum supply-chain are allowing more designers to choose polymer tantalum capacitors as alternatives to traditional solid tantalum capacitors, writes Roger Tall.
The TD series is a range of resin dipped tantalum capacitors de- signed for entertainment, commercial, and industrial equipment. They have sintered anodes and solid electrolyte.

History. Aluminum electrolytic capacitors (Al-e-caps) with liquid electrolytes were invented in 1896 by Charles Pollak.. Tantalum electrolytic capacitors with solid manganese dioxide (MnO 2) electrolytes were invented by Bell Laboratories in the early 1950s, as a miniaturized and more reliable low-voltage support capacitor to complement the newly invented transistor, see Tantalum capacitor.

Solid tantalum capacitors are a subtype of electrolytic capacitors that utilize the basic three-layer capacitor structure (conductor–dielectric–conductor) in the form of a tantalum anode, tantalum oxide dielectric, and a conductive cathode. Tantalum capacitors are polarized, meaning the applied voltage must remain positive.

But solid tantalum electrolytic capacitors can work above 50kHz. With the increase of frequency, tantalum capacitors will also show a decrease in capacity, but the decrease is relatively small. Data show that when working at 10kHz, the capacity of tantalum capacitors drops by less than 20%, while the capacity of aluminum electrolytic capacitors ...
