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

Supercapacitors – FC 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.

Safety Risks
(*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.

Supercapacitors – FC Series
Precautions for Use
• This series is exclusively for reflow soldering. It is designed for thermal conduction system such as combination use of
infrared ray and heat blow. Consult with KEMET before applying other methods.
• The reflow condition must be kept within reflow profile graphs shown below.
• Applying reflow soldering is limited to 2 times. After the first reflow, cool down the capacitor thoroughly to 5 – 35°C
before the second reflow.
Always consult with KEMET when applying reflow soldering in a more severe condition than the condition described here.

Supercapacitors – FC Series
Measurement Conditions
Capacitance (Charge System)
Capacitance is calculated from expression (9) by measuring the charge time constant (τ) of the capacitor (C). Prior to
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.

Self-Discharge Characteristic (0H – 5.5 V Products)
The self-discharge characteristic is measured by charging a voltage of 5.0 VDC (charge protection resistance: 0 Ω)
according to the capacitor polarity for 24 hours, then releasing between the pins for 24 hours and measuring the pin-topin voltage. The test should be carried out in an environment with an ambient temperature of 25° C or below and relative
humidity of 70% RH or below. The soldering is checked.
4. Dismantling
There is a small amount of electrolyte stored within the capacitor. Do not attempt to dismantle as direct skin contact with
the electrolyte will cause burning. This product should be treated as industrial waste and not is not to be disposed of by fi re.

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.
1.2 Fail rate in the field
Based on field data, the fail rate is calculated at approximately 0.006 Fit. We estimate that unreported failures are ten
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
Useful life of the supercapacitor will be significantly affected if used near heat emitting items (coils, power transistors
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.

Notes on Using Supercapacitors or Electric Double-Layer Capacitors (EDLCs) cont.
2. Mounting
2.1 Mounting onto a reflow furnace
Except for the FC series, it is not possible to mount this capacitor onto an IR / VPS reflow furnace. Do not immerse the
capacitor into a soldering dip tank.
2.2 Flow soldering conditions
Keep solder under 260°C and soldering time to within 10 seconds when using the flow automatic soldering method.
(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
iron under 400°C and soldering time to within 3 seconds. Always make sure that the temperature of the tip is controlled.
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
3.1 Temperature and humidity
Make sure that the supercapacitor is stored according to the following conditions: Temperature: 5 – 35°C (Standard
25°C), Humidity: 20 – 70% (Standard: 50%). Do not allow the build up of condensation through sudden temperature
change.
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.
