Product Guide High Performance Electrical Double-Layer Capacitors DMF Series www.murataamericas.com/edlc 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. Features Benefits High power output and high energy: 5.5V Leveling the high peak load up to hundreds of milli-seconds – Extend battery run time and cycle life by stable combination with EDLC – Enable the use of lower power battery or reduction of the number of series connections – Enable the use of high peak load applications without high power battery Compact and slim: 21.0mm x 14.0mm x 2.5mm Wide operation temperature range from -30°C to +70°C Low ESR: 40mΩ – 60mΩ – Stable ESR at lower temperatures Quick Charge and Discharge of High Energy ESR change @ -30°C < twice the nominal ESR – Secure power line from large load change and power down – Secure battery power down at lower temperatures – Shorten the standby time Low leakage current – Typical leakage less than 10μA@96hrs Maintenance-free energy storage device with flexible charge Long cycle life - exceeding 100k cycles Applications Peak Power Assist Energy Harvesting Systems – LED flash (DVC, DSC, smart phones), valve operation (smart meters), e-paper applications – Micro and macro energy harvesting systems Battery Peak Load Leveling Backup Applications – Point of sale equipment, tablet PCs, audio, smart meters, GPS/GPRS tracking systems, fuel cells, primary cell equipment, power tools – Solid state drives, UPS, last gasp applications 1 High Performance Electrical Double-Layer Capacitors Product Lineup Series Murata Part Number Rated Voltage Nominal ESR@1kHz Nominal Capacitance T 60mΩ 330mF 2.5 ±0.2mm 40mΩ 470mF 3.2 ±0.2mm Peak 5.5V Constant 4.2V Peak 5.5V Constant 4.2V DMF3R5R5L334M3DTA0 DMF DMF3Z5R5H474M3DTA0 Operating Temperature Min: - 30°C Max: +70°C Part Number Description DMF 3R 5R5 ➀ ➁ ➂ L 334 M 3D T A0 ➃ ➄ ➅ ➆ ➇ ➈ 1.

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. 8 High Performance Electrical Double-Layer Capacitors Packaging Tray(50 pcs/ Tray) Min Packaging Quantity (500pcs) Cover Tray Outer Package 10 trays Total 500 pcs Top View 500pcs Label Profile 500pcs Label Label Minimum Shipping Quantity: 500 pcs Storage Conditions Storage condition without opening outer package: 30°C 60%RH for 1 year (before opening outer package) *Note: This product cannot be baked.

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. 9 High Performance Electrical Double-Layer Capacitors Note 1.
