By optimising processes and co-operating with polymer suppliers, AVX is now able to manufacture a 125V tantalum polymer capacitor. The capacitors feature a conductive polymer electrode which reduces ignition failure and enhances ESR stability over temperature as well as volumetric efficiency. The electrode allows for a comparatively low derating, according to the company. The capacitors offered by the company include the single anode TCJ series with10µF or 35V and 1µF or 50V CV ratings and the multi-anode TCM Series rated at 22µF or 35V with a resistance of 25mΩ. The operating voltage of tantalum polymer capacitors used to be limited by the breakdown voltage. The new developments in polymer technology address these issues and may result in even higher-rated products in the future, claims the company. Typical applications can be found in the consumer space, e.g. telecommunications equipment, LED TVs and power supplies for notebook computers. They also have applications in the industrial area. Engineering samples of the initial offering, the TCJ 6.8µF/100V (V case) and 3.3µF/125V (D case) will be available from July onwards, with volume production starting in 2012.
