Explaining Capacitors and the Different Types | DigiKey
Capacitors are distinguished by the materials used in their construction, and to some extent by their operating mechanism. "Ceramic" capacitors for example use ceramic materials as a dielectric; "aluminum electrolytic" capacitors are formed using aluminum electrodes and an electrolyte solution, etc.
Tantalum Capacitors: Advantages & Considerations | Arrow
Using tantalum results in a very thin dielectric layer, resulting in a higher capacitance per volume and allowing for smaller capacitors that can still meet the needs of modern systems. In addition to the nice gain in capacitance per volume, the tantalum capacitors also have very low ESR or Equivalent Series Resistance reducing system …
Kyocera AVX Low ESR Tantalum Capacitors Technical Paper
Tantalum capacitors are particularly well suited as energy storage elements in ripple filter circuits due to their low ESR. Since AC ripple is continuous and periodic, the capacitor ESR results in a continuous generation of heat as the current flows in and out of the capacitor. This is especially true in high-frequency switching supplies and ...
