KEMET 47mF Supercapacitor -20 → +80% Tolerance, FMR 5.5V dc, Through Hole

FM Series Super capacitors, also known as Electric Double-Layer Capacitors (EDLCs), are intended for high energy storage applications.

Rectangular case
Wide range of temperature from −25°C to +70°C (all types except FMR) and −40°C to +85°C (FMR type)
Maintenance free
3.5 VDC, 5.5 VDC, and 6.5 VDC
Highly reliable against liquid leakage
Lead-free
Leads can be transverse mounted
Applications
Super capacitors have characteristics ranging from traditional capacitors and batteries. As a result, Super capacitors can be used like a secondary battery when applied in a DC circuit. These devices are best suited for use in low voltage DC hold-up applications such as embedded microprocessor systems with flash memory.
