FKS Aluminum Electrolytic Capacitors Panasonic FKS Aluminum Electrolytic Capacitors offer a smaller case size with the same performance as the larger conventional type. These capacitors use advanced foil technology with a capacitance range from 10μF to 13000μF and a voltage range from 6.3VDC to 50VDC. Panasonic FKS Aluminum Electrolytic Capacitors are AEC-Q200 qualified and RoHS compliant. Ideal applications include DC-to-DC converters, inverter and rectifier circuits, automotive industries, and power suppliers.
