FG Supercapacitors

KEMET FG Supercapacitors, also known as Electric Double-Layer Capacitors (EDLCs), are intended for high-energy storage applications. These supercapacitors offer a wide operating temperature range from -25°C to +70°C (FG & FGH types) and -40°C to +85°C (FGR type). The FG series operates in 3.5VDC and 5.5VDC voltages and offers high reliability against liquid leakage. These capacitors are maintenance-free, lead-free, and RoHS-compliant. KEMET FG Supercapacitors are ideal for the secondary battery in a DC circuit and low-voltage DC hold-up, such as embedded microprocessor systems with flash memory.
