Benefits
• Surface mount without holder
• Widerangeoftemperaturefrom−25°Cto+70°C
• Maintenance free
• Maximum operating voltages of 3.5 and 5.5 VDC
• Highly reliable against liquid leakage
• Lead-free and RoHS Compliant
Overview
FC Series Supercapacitors, also known as Electric
Double-Layer Capacitors (EDLCs), are surface mount type
components intended for high energy storage applications.
TheFCSeriesisdesignedspecificallyforreflowsoldering,
allowing them to be attached to a printed circuit board
(PCB) directly.
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
embeddedmicroprocessorsystemswithflashmemory.

Supercapacitors – FC Series
Performance Characteristics
Supercapacitors should not be used for applications such as ripple absorption because of their high internal resistance
(severalhundredmΩtoahundredΩ)comparedtoaluminumelectrolyticcapacitors.Thus,itsmainusewouldbe
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.

Heat-up, explosion Gas emission (*2)
(*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.

Capacitance (Charge System)
Capacitanceiscalculatedfromexpression(9)bymeasuringthechargetimeconstant(τ)ofthecapacitor(C).Priorto
measurement, the capacitor is discharged by shorting both pins of the device for at least 30 minutes. In addition, use the polarity
indicator on the device to determine correct orientation of capacitor for charging.

Capacitance (Discharge System)
As shown in the diagram below, charging is performed for a duration of 30 minutes once the voltage of the capacitor

from 3.0 to 2.5 V upon discharge at 0.22 mA per 0.22 F, for example, and calculate the static capacitance according to the
equation shown below.
Note: The current value is 1 mA discharged per 1 F.
Capacitance (Discharge System – 3.5 V, 3.6 V)
As shown in the diagram below, charging is performed for a duration of 30 minutes once the voltage of the capacitor
terminal reaches 3.5 V (3.6 V). Then, use a constant current load device and measure the time for the terminal voltage to
drop from 1.8 to 1.5 V upon discharge at 1.0 mA per 1.0 F, for example, and calculate the static capacitance according to the
equation shown below.
Capacitance (Discharge System – HV Series)
As shown in the diagram below, charging is performed for a duration of 30 minutes once the voltage of the capacitor

Supercapacitors – FC Series
Notes on Using Supercapacitors or Electric Double-Layer Capacitors (EDLCs)
1. Circuitry Design
1.1 Useful life
The FC Series Supercapacitor (EDLC) uses an electrolyte in a sealed container. Water in the electrolyte can evaporate
while in use over long periods of time at high temperatures, thus reducing electrostatic capacity which in turn will create
greater internal resistance. The characteristics of the supercapacitor can vary greatly depending on the environment in
which it is used. Basic breakdown mode is an open mode due to increased internal resistance.
1.2Failrateinthefield
Basedonfielddata,thefailrateiscalculatedatapproximately0.006Fit.Weestimatethatunreportedfailuresareten
times this amount. Therefore, we assume that the fail rate is below 0.06 Fit.
1.3 Exceeding maximum usable voltage
Performance may be compromised and in some cases leakage or damage may occur if applied voltage exceeds
maximum working voltage.
1.4 Use of capacitor as a smoothing capacitor (ripple absorption)
As supercapacitors contain a high level of internal resistance, they are not recommended for use as smoothing
capacitors in electrical circuits. Performance may be compromised and, in some cases, leakage or damage may occur if
a supercapacitor is used in ripple absorption.
1.5 Series connections
As applied voltage balance to each supercapacitor is lost when used in series connection, excess voltage may be
applied to some supercapacitors, which will not only negatively affect its performance but may also cause leakage
and/or damage. Allow ample margin for maximum voltage or attach a circuit for applying equal voltage to each
supercapacitor (partial pressure resistor/voltage divider) when using supercapacitors in series connection. Also,
arrange supercapacitors so that the temperature between each capacitor will not vary.
1.6 Case Polarity
The supercapacitor is manufactured so that the terminal on the outer case is negative (-). Align the (-) symbol during
use. Even though discharging has been carried out prior to shipping, any residual electrical charge may negatively affect
other parts.
1.7 Use next to heat emitters
Usefullifeofthesupercapacitorwillbesignificantlyaffectedifusednearheatemittingitems(coils,powertransistors
and posistors, etc.) where the supercapacitor itself may become heated.
1.8 Usage environment
This device cannot be used in any acidic, alkaline or similar type of environment.

2.2 Flow soldering conditions
Keepsolderunder260°Candsolderingtimetowithin10secondswhenusingtheflowautomaticsolderingmethod.
(Except for the FC and HV series)
2.3 Installation using a soldering iron
Care must be taken to prevent the soldering iron from touching other parts when soldering. Keep the tip of the soldering
ironunder400°Candsolderingtimetowithin3seconds.Alwaysmakesurethatthetemperatureofthetipiscontrolled.
Internal capacitor resistance is likely to increase if the terminals are overheated.
2.4 Lead terminal processing
Do not attempt to bend or polish the capacitor terminals with sand paper, etc. Soldering may not be possible if the
metallic plating is removed from the top of the terminals.
2.5 Cleaning, Coating, and Potting
Except for the FM series, cleaning, coating and potting must not be carried out. Consult KEMET if this type of procedure
is necessary. Terminals should be dried at less than the maximum operating temperature after cleaning.
3. Storage

3.2 Environment conditions
Make sure there are no corrosive gasses such as sulfur dioxide, as penetration of the lead terminals is possible. Always
store this item in an area with low dust and dirt levels. Make sure that the packaging will not be deformed through heavy
loading, movement and/or knocks. Keep out of direct sunlight and away from radiation, static electricity and magnetic
fields.
3.3 Maximum storage period
This item may be stored up to one year from the date of delivery if stored at the conditions stated above.
