Conductive Polymer Capacitors

[Announcement] The Transfer of the Tantalum Capacitor Business
ROHM Co., Ltd. has reached a final agreement on the transfer of assets related to the tantalum capacitor business. Read news release open in new tab for more detail.

Conductive polymer capacitors use a conductive polymer for the cathode layer. Compared to manganese dioxide type tantalum capacitors, conductive polymer capacitors achieve a significantly lower ESR (equivalent series resistance). It is effective for flowing high ripple current and removing noise at high frequencies. In the event of a failure, the conductive polymer is insulated, providing a safe structure.
ROHM's conductive polymer capacitors are small, low-profile and have a large capacitance through a new and efficient package design. Compared to ceramic capacitors, there is no reduction in capacitance due to DC bias, and there is no ringing or vibration due to no piezoelectric characteristics.
