High Reliability KEMET Organic Capacitor (KO-CAP)
T540 Polymer Commercial Off-the-Shelf (COTS)
Overview
The KEMET Organic Capacitor (KO-CAP) is a tantalum capacitor The T540 Series KO-CAP offers the same advantages as the
with a Ta anode and Ta2O5 dielectric. A conductive organic
polymer replaces the traditionally used MnO2 as the cathode
T525 Series but is also designed for the Commercial Off-the-Shelf
(COTS) requirements of defense and aerospace applications. This
plate of the capacitor. This results in very low ESR and improved surface mount product offers a tin lead (SnPb) leadframe finish,
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.
surge current testing options and standard or low ESR levels.
