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.
