The FCR Series from KEMET Corporation are Supercapacitors that are designed for high-energy storage applications. They have capacitance up to 0.1 F and a capacitance tolerance of -20/+80%. These capacitors have a voltage rating of 5.5 V and an equivalent series resistance (ESR) of less than 500 ohms. They have an operational life of up to 2000 hours at 85°C. These RoHS-compliant supercapacitors are highly reliable against liquid leakage. They are available in holder-less surface-mount packages and are ideal for low-voltage DC hold-up applications such as embedded microprocessor systems with flash memory.
