AVX Corporation, a manufacturer of advanced passive components and interconnect solutions, has announced the capability to manufacture a 125V tantalum polymer capacitor, more than twice the rated voltage of similar products on the market today. Passing the 100V milestone for the first time represents a significant development in the field of high voltage tantalum capacitors and extends the range of such devices available to engineers for new consumer product applications such as telecommunications equipment, LED TVs and power supplies for notebook computers, as well as a host of industrial applications.
The new high voltage tantalum capacitor was developed by optimising processes which enhance capacitor performance and working in close co-operation with polymer suppliers. Conductive polymer has been proven to provide low ESR and reduced ignition failure mode solution. In addition, due to the nature of polymer capacitors surge robustness, lower derating of 20% can be used. However, the working voltage of tantalum-polymer capacitors was limited until now due to the maximum achievable breakdown voltage. AVX’s new developments in polymer technology addresses these limited working voltage issues and is expected to result in even higher-rated products in the future.
Engineering samples in limited quantities of the new TCJ 6.8µF/100V (V case) and 3.3µF/125V (D case) high capacitance, high voltage tantalum capacitors will be available from July onwards, with volume production starting in 2012.
