What makes tantalum capacitors unique is the usage of tantalum for the anode of the device.
Ceramic cap vs tantalum.
Tantalum capacitors are a subtype of electrolytic capacitors that use tantalum metal for the anode.
What is a tantalum capacitor.
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.
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.
Tantalum capacitors have superior frequency characteristics and long term stability.
When your schematic calls for a capacitor you have many choices.
Electrolytic ceramic silver mica mylar monolithic tantalum glass or supercapacitors just to name a few.
As shown the conditions for life testing are not.
Ceramic capacitor vs tantalum capacitor.

In this post we compare tantalum capacitor vs ceramic the differences between and benefits of the two.
It can be confusing especially if you have a specific application that requires extra noise filtering or high voltage handling capabilities.

This makes it possible to further decrease set thickness to a level that is difficult or impossible to achieve.
Surface mount tantalum capacitors typically feature a bottom electrode structure.
Tantalum ceramic capacitors.
Ceramic chips are rated from 6 3 v to 200 v with others up to 5 kv.
So clearly ceramic technology offers greater versatility.
Tantalum capacitors configured with electrodes on the bottom of the package are not susceptible to shorts even when mounted close together facing each other.
A tip and ring capacitor commonly used in telecommunications requires a working voltage of 250 v.
