KEMET T521 Series Organic (KO-CAP) Polymer Tantalum Capacitor - Expansion

KEMET now offers an Organic Capacitor version of its T521 Series High Voltage Polymer Tantalum Capacitor product line. KEMET's organic capacitor (KO-CAP) is a tantalum capacitor with a Ta anode and Ta₂O₅ dielectric and a conductive organic polymer that replaces the traditionally used MnO₂ as the cathode plate of the capacitor, resulting in very low ESR and improved capacitance retention at high frequency. Other KO-CAP features include voltage ratings to 35V, volumetric efficiency, up to 68µF capacitance value, high reliability, and stable temperature characteristics.

KEMET's T521 Series High Voltage Polymer Tantalum Capacitor is the first 35 volt rated polymer tantalum chip capacitor. This new technology involves advances in materials and the manufacturing process to produce a polymer tantalum capacitor suitable for applications of up to 28V of continuous duty, high voltage 16V - 35V. The T521 series features up to 68uF capacitance value, high ripple current capability, safe failure mode, and low ESR. The KEMET T521 Series High Voltage Polymer Tantalum Capacitor is volumetrically efficient, has stable temperature characteristics, is Pb Free when ordered with 100% Sn Termination Finish, RoHs compliant, and halogen free.
