Tantalum Capacitors

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.

TCT,TC Series

Low
Profile

High capacitance

Low
ESR

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.

TCO,TCTO Series

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.

TCFG Series

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.
