Tantalum Capacitors: Advantages Considerations

07/12/2016  What makes tantalum capacitors unique is the usage of tantalum for the anode of the device. This anode is set up as one chunk of material inside of the case, which is very different from the layering style used in MLCC capacitors where the material is sandwiched on itself and then capped on the ends. Using tantalum results in a very thin dielectric layer, resulting in a higher capacitance per ...

Tantalum - Wikipedia

Tantalum electrolytic capacitors exploit the tendency of tantalum to form a protective oxide surface layer, using tantalum powder, pressed into a pellet shape, as one "plate" of the capacitor, the oxide as the dielectric, and an electrolytic solution or conductive solid as the other "plate". Because the dielectric layer can be very thin (thinner than the similar layer in, for instance, an ...

22/10/2015  Why avoid using tantalum capacitors? From what I can find these are the main reasons to avoid tantalum capacitors in your design: Financial: Tantalum capacitors are relatively expensive even when supply and demand are balanced. Not too long ago prices went sky high due to a shortage in raw materials. Reliability: There are numerous reports of tantalum capacitors spontaneously combusting.
