RF8 FPCAPs Nichicon RF8 Functional Polymer Aluminum Electrolytic Capacitors (FPCAPs) feature low ESR and low ESL at a high frequency range, high ripple current capability, and long life and high reliability. By using functional polymer cathode, frequency and temperature characteristics are greatly improved. Applications for RF8 FPCAPs include switching power supplies and DC/DC converters, buck up power supplies of CPUs (VRM, etc.), and miniature high power supplies.
