Energy Storage Capacitor Technology Comparison and Selection
Tantalum and Tantalum Polymer capacitors are suitable for energy storage applications because they are very efficient in achieving high CV. For example, for case sizes ranging from EIA 1206 (3.2mm x 1.6mm) to an EIA 2924 (7.3mm x
Capacitor types
Another type – the electrochemical capacitor – makes use of two other storage principles to store electric energy. In contrast to ceramic, film, and electrolytic capacitors, supercapacitors (also known as electrical double-layer capacitors (EDLC) or ultracapacitors) do not have a conventional dielectric. ...
Tantalum and Ceramic Capacitors
Tantalum capacitors often fail, by going short circuit. The high current that they then pass can make them very hot and even burst in to flames. The company that I work for are designing them out of new products and replacing them with ceramic capacitors. LarryD October 25, 2021, 5:59pm 17. JohnLincoln:
capacitor
In fact, many ceramic capacitors I suspect are the exact same part but with different part numbers, the same 4.7µF capacitor being sold as both a 35V and 50V capacitor under different labels. The graph of some MLCCs'' capacitance vs. bias voltage is identical, save for the lower voltage one having its graph truncated at its rated voltage.

Two types of ceramic capacitors are widely used in modern electronics: multilayer ceramic (MLCC) and ceramic disc, as shown in Fig. 8.5A and B [6], [8]. Ceramic capacitors typically have small capacitances between 1 nF and 1 μF and a low maximum rated voltage compared with electrolytic capacitors and are nonpolarized.
Why use a tantalum instead of a ceramic capacitor?
Miomio. 123 1 8. General note: ESL and ESR aren''t the only "nonidealness" measures for a capacitor. One that''s often overlooked is nonlinearity, usually quantified via THD. In that regard, both tantalum and ceramic are among the worse types, with some ceramics being really really bad. – leftaroundabout.
Are tantalum capacitors safe for use in new designs?
asked Feb 10, 2014 at 17:20. Russell McMahon ♦. 151k 18 216 395. Tantalum capacitors are safe if used properly, just kindof dumb in new designs nowadays. Between multi-layer ceramics and solid aluminum, there is really very little reason to use a tantalum in a new design today. –. Feb 10, 2014 at 21:13. Somebody downvoted this.
