AVX says it can now manufacture a 125V-rated tantalum polymer capacitor.
This is the first time it has passed the 100V level and is looking to open up new product applications such as LED TVs and industrial applications.
According to the supplier, the conductive polymer has been proven to provide low ESR and reduced ignition failure mode solution.
“Due to the nature of polymer capacitors surge robustness, lower derating of 20% can be used,” said AVX.
“However, the working voltage of tantalum-polymer capacitors was limited until now due to the maximum achievable breakdown voltage,” said the company.
There is potential for 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.
