This slide shows the derating advantages KEMET’s polymer tantalum capacitors have over traditional MnO2 tantalum capacitors. As noted, voltage derating is divided into two classes according to voltage rating. For less than or equal to 10V ratings, a 10% derating is recommended. For voltage ratings greater than 10V, a 20% derating is recommended. Currently, polymer tantalum capacitors have two category temperature classes including 105ºC and 125ºC. KEMET’s T520 and T528 series have both a category and rated temperature of 105ºC. Therefore there are no temperature derating requirements. KEMET’s T525 and T530 series have a category temperature of 125ºC but maintain a rated temperature of 105ºC. So, derating of the voltage rating is required as the application temperature exceeds 105ºC.  KEMET’s T521 series currently consists of a mix of 105ºC and 125ºC category temperature products.
