High Performance Electrical Double-Layer Capacitors
To meet consumer demand for mobile devices with greater efficiency
and functionality, Murata began focusing its R&D efforts on Electrical
Double-Layer Capacitors (EDLC) in 2008, at which time we made a
strategic decision to license leading-edge supercapacitor technology
from CAP-XX Limited (CAP-XX), an Australia-based firm. Working
from this collaborative basis, Murata has enhanced the design and
manufacture of these high power (low ESR) EDLCs in a compact, slim
package, and we continue our research efforts to develop even better
and higher performing products.
Electrical Double-Layer Capacitors (EDLCs), often referred to as
supercapacitors, are energy storage devices with high power density
characteristics that are up to 1,000 times greater than what is typically
found in conventional capacitor technology. Murata’s Electrical Dou
ble Layer Capacitor combines these advanced characteristics in a small
and slim module. Optimization of electrochemical systems, including
the electrode structure, enables flexible charging and discharging
from high to low output over a range of temperatures. By supporting
momentary peak load, the components also level battery
load and can drive high-output functions that are difficult for
batteries alone.

High Performance Electrical Double-Layer Capacitors
Caution Before Use
CAUTION

This device must be used within rated voltage. Over voltage may cause electrolyte leakage or swelling.

This device has polarity. Please do not reverse polarity when in use. Reverse polarity may damage the electrolyte or electrode
inside. Please verify the orientation of the capacitor before use in accordance with the markings of polarity on the products.

Avoid outer case contact to ground plane, as this may cause leakage current failure.

This device cannot be used under any acidic or alkaline environment.

This device uses a relatively low vapor pressure liquid electrolyte. At high altitudes (with low external pressure), internal
resistance or other performance may decrease. If you would like to use this product at high altitude, please consult a Murata
representative first.

DMF series product has two individual cells connected electrically in series. Please ensure that peak voltage is less than 2.75V
per cell and less than 2.1V per cell for constant load. Murata strongly recommends the use of active balancing control circuits or
balance resistors. For further details, contact your local Murata representative.

When connecting two or more capacitors in series, voltage load may vary between capacitors. This could lead to excessive
voltage on any capacitor. In these cases, please consult a Murata representative beforehand.
CAUTION for Soldering and Assembling
1. These parts should not be soldered using re-flow or flow profiles. Please use connection methods that prevent exposure to
temperatures beyond the maximum allowable range. These may include hand soldering, ultrasonic welding, etc.
2. Please do not apply excessive force to the capacitor during insertion as well as after soldering. Excessive force may result in
damage to electrode terminals and/or degradation of electrical performance.
3. Hand Soldering
Please solder under the following conditions:
Soldering iron temperature at 350°C ±10°C;
Solder iron wattage: 70W or less;
Soldering time: 3.0+1/-0sec.
Allowable soldering passes: 3 times/device – allow at least for 15 seconds between successive soldering.
Please do not touch laminate package directly with the soldering iron.
4. Do not wash the device after soldering.

Response to IATA Dangerous Goods Regulations
According to the 54th Edition of IATA Dangerous Goods Regulations effective from January 1, 2013, Electrical Double-Layer
Capacitors (ELDCs) with an energy storage capacity greater than 0.3 Wh are treated as dangerous goods and introduced as
UN3499 in Class 9.
However, the energy storage capacity of each of Murata’s EDLCs is not greater than 0.3. Therefore, Murata’s EDLCs are not
covered by this regulation.
