Tantalum Polymer High-Reliability (HRA) Capacitors – T540/T541/T543 Series

The KEMET, a YAGEO company, organic capacitor (KO-CAP) is a high-reliability (HRA) solid polymer capacitor. A conductive organic polymer replaces the legacy MnO2 as the counter-electrode of the capacitor. This results in 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 V. The HRA polymer electrolytic offers the same performance advantages as other KO-CAP series with screening options associated with high-reliability applications. These HRA-grade components offer several surge current screening options. The recommended application derating for these capacitors is 10% to 20%, rendering them suitable for application voltages from 0.8 V_DC to 48 V_DC or 50 V_DC. These polymer solid electrolytic capacitors are available with failure rate options as defined by KEMET's KO-CAP reliability assessment method.

The T540 series KO-CAP uses a polymer cathode design that delivers low ESR values. It offers the same advantages as the commercial T525 series but is also suitable for the high-reliability requirements of telecommunications, computer, military, and aerospace applications.

The T541 series KO-CAP uses multiple-polymer anode design that deliver the lowest ESR values available in the industry. It offers the same advantages as the commercial T530 series but is also suitable for the high-reliability requirements of telecommunications, computer, military, and aerospace applications.

The T543 series KO-CAP uses polymer cathode design that delivers the low ESR values and offers the same advantages as the industrial T520 series, the T543 series is a KEMET solution for designers seeking for cost effective solution up-screened to high-reliability (HRA) equivalents.
