Supercapacitors
FT Series
Overview
Applications
Supercapacitors have characteristics ranging from
traditional capacitors and batteries. As a result,
supercapacitors 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.
FT Series Supercapacitors, also known as Electric Double-
Layer Capacitors (EDLCs), are intended for high energy
storage applications.
Benefits
• Wide range of temperature from −40°C to +85°C
• Maintenance free
• Maximum operating voltage: 5.5 VDC
• Highly reliable against liquid leakage

Supercapacitors – FT Series
Performance Characteristics
Supercapacitors should not be used for applications such as ripple absorption because of their high internal resistance
(several hundred mΩ to a hundred Ω) compared to aluminum electrolytic capacitors. Thus, its main use would be
similar to that of secondary battery such as power back-up in DC circuit. The following list shows the characteristics of
supercapacitors as compared to aluminum electrolytic capacitors for power back-up and secondary batteries.

(*1) Aluminum electrolytic capacitors and supercapacitors have limited lifetime. However, when used under proper conditions, both can operate within a
predetermined lifetime.
(*2) There is no harm as it is a mere leak of water vapor which transitioned from water contained in the electrolyte (diluted sulfuric acid). However,
application of abnormal voltage surge exceeding maximum operating voltage may result in leakage and explosion.
