The KEMET Organic Capacitor (KO-CAP) is a high reliability polymer COTS (Commercial-Off-The-Shelf) capacitor. A conductive organic polymer replaces the more common MnO2 as the cathode plate of the capacitor. This results in very low ESR and improved capacitance retention at high frequency. The KO-CAP may also be operated at steady state voltages at 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.
The T540 Series KO-CAP offers the same advantages as the T525 Series but is also suitable for the high reliability requirements of telecommunications, computer, military and aerospace applications. This surface mount product offers a tin lead (SnPb) leadframe finish, surge current testing options and standard or low ESR levels.
