When your schematic calls for a capacitor you have many choices.
Output capacitor of a dc dc converter edit.
However ceramic capacitors can be made to trend linearly by narrowing the operating temperature ranges and accounting for the temperature response during the design phase.
Generally speaking while electrolytic capacitors provide the largest capacitance they suffer significant degradation in capacitance and leakage current at higher temperatures and frequencies.
Surface mount tantalum capacitors typically feature a bottom electrode structure.
The application typically dictates the best choice of capacitor type multilayer ceramic capacitor mlcc aluminum electrolytic polymer or tantalum to use in the design.

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 capacitors configured with electrodes on the bottom of the package are not susceptible to shorts even when mounted close together facing each other.
Url layout issues.
The dc working voltage of tantalum chip capacitors is limited to between 4 v and 50 v.
This is significantly less in ceramic capacitors than in tantalums 0 001 μa compared to 0 5 30 μa.
When subjected to changes in temperature tantalum capacitors usually show linear capacitance change while ceramic capacitors usually have a non linear response.
Ceramic chips are rated from 6 3 v to 200 v with others up to 5 kv.
This makes it possible to further decrease set thickness to a level that is difficult or impossible to achieve.
