KEMET Organic Capacitor (KO-CAP) T528 Low ESL/Facedown Terminal Polymer Tantalum Overview The KEMET Organic Capacitor (KO-CAP) is a tantalum capacitor with a Ta anode and Ta2O5 dielectric. A conductive organic polymer replaces the traditionally used MnO2 as the cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency. The KO-CAP also exhibits a benign failure mode which eliminates the ignition failures that can occur in standard MnO2 tantalum types. KOCAPs may also be operated at steady state voltages up to 90% of rated voltage for part types with rated voltages of ≤ 10 volts and up to 80% of rated voltage for part types > 10 volts with equivalent or better reliability than traditional MnO2 tantalum capacitors operated at 50% of rated voltage. The T528 Series KO-CAP combines ultra-low ESR and high capacitance in a package design that offers the lowest ESL in the market for this type of product. This series offers exceptional performance for high-speed server and microprocessor decoupling – designs that are driving the demand for low inductance chips. The T528 uses a different termination design that allows for a reduction in the inductance loop area and comes in a low profile 1.7 mm case height. These product features offer the advantage of improved capacitance retention at frequencies of up to 1 MHz.
