KEMET T545 Series Tantalum Capacitors

KEMET T545 Series High Energy Polymer Tantalum Capacitors feature a tantalum anode and a Ta₂O₅ dielectric. These devices utilize a conductive organic polymer as the cathode, replacing the traditional MnO₂, which results in extremely low ESR and improved capacitance retention at high frequencies. The polymer technology used in these components provides a benign failure mode and eliminates the risk of ignition failures that can occur in standard MnO₂ tantalum capacitors. The T545 series is designed to deliver the highest energy per cubic centimeter of any tantalum surface mount device and makes it ideal for applications requiring high energy at relatively low voltages. These organic capacitors are subjected to 100% thermal shock and voltage aging to ensure long-term reliability.
