As general characteristics, tantalum capacitors feature
compact package sizing & larger capactance and also
better temperature & DC bias characteristics, in contrast to multi-layer ceramic capacitors.
Types of chip tantalum capacitors available from ROHM are
various such as, "Bottom-surface electrode type" having the electrode at the package's bottom, "Conductive polymer type" employing conductive polymer materials in cathode for low ESR, "Fail-safe open function built-in type" which is flame-retardant due to internal fusing mechanism and "Standard type" long-seller with market-proven stable supply & quality.

Bottom-surface electrode type tantalum capacitor - a good
solution for the limited space !
Significant increase of capacitance per size and lower
profile are achieved by employing the bottom-surface electrode structure, compared with conventional package.
Ultra low ESR
Low
Profile
Conductive polymer type tantalum capacitor, for high-frequency circuit !
Conductive polymer is emplobyed for cathode materials and ESR (Equivalent Serial Resistnace) is dramatically reduced.
High reliability
Advanced safety precautions !
Fail-safe open function built-in tantalum capacitor contains
fusing mechanism which shuts off the current in case
of abnormal heating.
Small
Standard small surface mount tantalum capacitor series.
This is most popular type.
