Automotive capacitors deliver higher stability under harsh conditions of humidity and temperature

19-01-2015 | Mouser Electronics | Passives

Available now from Mouser stock, Kemet T591 Series tantalum polymer capacitors are designed to deliver higher stability under harsh conditions of humidity and temperature in applications such as decoupling and filtering in a variety of market segments - automotive in particular. The series features polymer cathode technology for ultra-low ESR and improved capacitance retention at high frequency. The polymer technology also exhibits a benign failure mode which eliminates the ignition failures that can occur in standard MnO2 tantalum types. The T591 polymer tantalum capacitors can be operated at voltages up to 90% of rated voltage for part types with rated voltages of ?10V with equivalent or better reliability than traditional MnO2 tantalum capacitors operated at 50% of rated voltage. The AEC-Q200-compliant devices are specially designed for DC-DC converters in automotive applications, where harsh conditions (high humidity and temperature) are a concern.
