Kemet expands KO-CAP Conductive Polymer portfolio

“The release of our T522 Series highlights Kemet’s continued commitment to capacitor technology advancements in the areas of portable electronics and other applications seeking improved battery life,” said Jayson Young, Kemet Technical Product Manager for Polymer Capacitors. “These devices offer the lowest leakage values available in polymer tantalum capacitors, with upper leakage limits that are up to 70% lower than other conductive polymer capacitor products.” The T522 Series is a Kemet Organic Capacitor (KO-CAP) which utilizes organic conductive polymer as the cathode plate of the capacitor and is designed to meet the needs of leakage sensitive applications such as battery supported circuits. Kemet offers this solution in low profile and standard case height configurations with capacitance values up to 470µF in 6.3V ratings and ESR offerings as low as 25mΩ. The KO-CAP is a tantalum capacitor with a Ta anode and a Ta2O5 dielectric. KO-CAP devices eliminate the ignition failures that can occur in standard MnO2 tantalum types and may also be operated at steady state voltages up to 90% of rated voltage. Typical applications for the T522 Series include battery-dependent applications such as handheld consumer electronics, global tracking systems, wireless sensors, and energy harvesting.
