KEMET T591D686M020ATE050 Datasheet & Stock

The T591 series organic SMD Tantalum Capacitor with a conductive polymer cathode capable of delivering very low ESR and improved capacitance retention at high frequencies. KO-CAP combines the low ESR of multilayer ceramic, the high capacitance of aluminium electrolytic and the volumetric efficiency of tantalum into a single surface mount package. Unlike liquid electrolyte-based capacitors, KO-CAP has a very long operational life and high ripple current capabilities. This high humidity/high temperature polymer electrolytic series delivers higher capacitance and ESR stability under harsh environmental conditions.
