Tantalum capacitors are a subtype of electrolytic capacitors that use tantalum metal for the anode.
Ceramic cap vs tantalum.
So clearly ceramic technology offers greater versatility.
What is a tantalum capacitor.
Electrolytic ceramic silver mica mylar monolithic tantalum glass or supercapacitors just to name a few.
When your schematic calls for a capacitor you have many choices.
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.
Surface mount tantalum capacitors typically feature a bottom electrode structure.
What makes tantalum capacitors unique is the usage of tantalum for the anode of the device.
A tip and ring capacitor commonly used in telecommunications requires a working voltage of 250 v.
Ceramic chips are rated from 6 3 v to 200 v with others up to 5 kv.
The dc working voltage of tantalum chip capacitors is limited to between 4 v and 50 v.
Ceramic capacitor ir life test.
Tantalum capacitors have superior frequency characteristics and long term stability.
It can be confusing especially if you have a specific application that requires extra noise filtering or high voltage handling capabilities.

Ramic and tantalum capacitor types are factors of polarity temperature dc bias effect ac signal level effects and fre quency response with the parasitic contributions within each ii there are significant differences in construction between multilayer ceramic mlc and tantalum capacitors.
Tantalum capacitors configured with electrodes on the bottom of the package are not susceptible to shorts even when mounted close together facing each other.
This makes it possible to further decrease set thickness to a level that is difficult or impossible to achieve.
Figure 9 depicts the life test conditions for various types of ceramic and tantalum capacitors made by several different manufacturers and the allowable change in insulation resistance and or dcl cv.
Tantalum ceramic capacitors.
As shown the conditions for life testing are not.
