RPS & RPA Aluminum Electrolytic Capacitors Nichicon RPS and RPA Conductive Polymer Aluminum Electrolytic Capacitors offer low ESR, capacitance range from 8.2µF to 1500µF, voltage range from 2.5VDC to 63VDC, and an operating temperature range from -55°C to +105°C. Nichicon RPS and RPA Conductive Polymer Aluminum Electrolytic Capacitors are small aluminum solid electrolytic capacitors that offer higher performance (low resistance), greater reliability, large capacitance, high ripple current capability, and the reduction of high frequency noise. The capacitors are lead-free and complies with RoHS and are available in radial leads and SMD types. Ideal applications include switching power supply and DC/DC converters, back-up power supplies of CPU (VRM, etc.), and miniature high power supplies.
