T541 Polymer Commercial Off-the-Shelf (COTS) Multi

T541 Polymer Commercial Off-the-Shelf (COTS) Multi

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. This advancement combined with the use of a multiple anode design delivers the lowest ESR values available in the industry. 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 T541 Series KO-CAP offers the same advantages as the T530 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.
