RSB0E391MCN1GS, Aluminum Organic Polymer Capacitors 2.5V 390uF 20% Tol.

SS, SA, & SB Aluminum Electrolytic Capacitors
Nichicon SS, SA, and SB Aluminum Electrolytic Capacitors are high-capacitance FPCAP devices offering a 10µF to 560µF capacitance range. Nichicon SS, SA, and SB 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 series is lead-free and complies with RoHS. Ideal applications for the FPCAP series are switching power supply and DC/DC converters, backup power supplies of CPUs, and miniature high power supplies.
