Electric Double Layer Capacitor RF series

Caution
1.This specification guarantees the quality and performance of the product as individual components. Before use,
check and evaluate their compatibility with installed in your products.
2.Do not use the products beyond the specifications described in this document.
3.Electrolyte is used in the products. Therefore, misuse can result in rapid deterioration of characteristics and
functions of each product. Electrolyte leakage damages printed circuit and affects performance, characteristics, and
functions of customer system.
4.Over Voltage
If Gold Capacitor is used at a voltage exceeding its maximum operating voltage, not only is its lifetime shortened but
also depending on the actual voltage, gas generated by electrochemical resections inside the capacitor may cause it
to leak or rupture.
5.Polarity
Be sure to verify the polarity of the capacitor before use. If a reverse voltage is applied for a long time, capacitor
lifetime is shortened and serious damage such as electrolyte leakage may occur.
6.Ripple current
Gold Capacitors have a higher internal resistance than electrolytic capacitors and are more susceptible to internal
heat generation when the temperature of the element rises, reaction current flows inside the Gold Capacitor,
generating reaction products and raising internal resistance even further. This makes it difficult to maintain capacitor
temperature 3°C measured at the surface of the capacitor.
7.Connection capacitors in series
Taking into consideration the possibility of an imbalance in the voltage across the capacitors, make sure that the
voltage applied to each capacitor will not exceed the maximum operating voltage. If the voltage balance breaks
down, an over voltage condition could result. To prevent this from occurring, add a voltage-driving resistor in parallel
with each capacitor, allowing the capacitor’s leakage current.
8.Environmental conditions
Avoid the use of capacitors at a temperature above the maximum operating temperature. In this case, it may cause
the increase of electrolyte vapor pressure and the gas generation by electrochemical reactions which result in
inner-pressure rise, serious damage and electrolyte leakage.
9.Mounting considerations
Double-side circuit board
Do not set wiring pattern directly to the mounted capacitor, and pass between terminals. If the electrolyte leaks,
short circuit may occur and tracking or migrations are anticipated.
Through hole board
Do not locate the capacitor close to circuit board. Solder blowing out of the holes possibly causes the short circuit.
10.Do not apply any strong force to the capacitor after circuit installation has been completed.
11.Do not use glue, which contain a halogen.
12.Circuit board cleaning
Series NF and F are not suitable for circuit board cleaning after mounting process. Series NF and F use the spring
plate between the inner cells and let them connect by pressure. If the abstergent soaks into the connection and
makes it wet, it is possible to increase contact resistance between the inner cells to cause to be rusted on the case.
If you need circuit board cleaning, please use Series SG or SD.
