In 2015 technical breakthroughs allowing full AEC-Q200 qualification of tantalum polymer caps have addressed the concerns with capability and safety. Alleviation of these concerns have come at a time when market drivers such as connectivity and self-driving functionality are requiring better capacitance solutions for the various CPU, logic, and input rails. In regards to new automotive requirements with electrical vehicles and autonomous driving ultra low ESR and extended life capability are a must. In this presentation, the product features and electrical performance, including accelerated storage performance, of these fully qualified 125ºC AEC-Q200 polymer tantalum capacitors will be provided.
