The new TCN Series tantalum polymer capacitors from AVX use an “undertab” design to maximize volumetric efficiency, enabling these devices to provide what is claimed to be the industry's highest CV rating-- 150µF/6.3V-- in T and L case sizes measuring only 3.5mm x 2.8mm with a profile of only 1.2mm and 1.0mm, respectively.
The CV rating and low profile package make the capacitors suitable for small power modules and handheld devices such as mobile phones.
The first TCN Series parts that have been released include the 150uF 6.3V devices in two 3528 case sizes - L case with a profile of 1.0mm and the T case which measures 1.2mm high. Additional TCN Series undertab polymer capacitors will be released during 2011, according to AVX.
