AVX Corporation, a leading manufacturer of passive components and interconnect solutions, has expanded its wide range of SMD tantalum polymer capacitors to include new TCN series devices that deliver industry’s highest CV rating in a low profile package.
TCN tantalum polymer capacitors use an ‘undertab’ design to optimize the internal maximum volumetric efficiency, enabling these parts to offer the popular 150µF/6.3V rating in an L case measuring just 3.5 x 2.8mm and with a profile of only 1mm.

The 150µF/6.3V tantalum polymer capacitor is a favourite choice of mobile phone manufacturers for power module stabilization applications. The new TCN series devices continue the miniaturization trend in electronic devices, allowing designers to produce smaller, thinner mobile devices or to increase functionality within the same product dimensions. The first TCN parts that have been released include 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. Further high volumetric efficiency TCN series ‘undertab’ polymer capacitors will be released during 2011.

TCN polymer capacitors are suitable for continuous operation with just 20% voltage derating due to their reduced ignition failure mode and surge current robustness. Tantalum capacitors in general are more stable against changes in operational temperature and applied voltage than comparable multilayer ceramic capacitors (MLCCs). TCN polymer tantalum capacitors are RoHS-compliant and contain no halogens, which top equipment manufacturers are anxious to eliminate. In addition, the conductive polymer cathode is inherently low oxygen bearing which helps to negate ignition failures - unlike other tantalum capacitor technologies which can be susceptible to this failure mode.
