Directions for use
1. Polarity
The FPCAP has polarity. Consequently, make sure polarity is never reversed when using.
If polarity is reversed, leakage current could increase or lifetime could decrease.
2. Applied Voltage
Under no circumstances can reverse voltage be applied. It may cause a short circuit.
3. Sudden charge and discharge
Keep sudden charge and discharge to a minimum. It may create a short circuit or cause high leakage current.
In this case, it is recommended to use a protection circuit in order to maintain high reliability.
Regardless, using protection circuit to ensure reliability is recommended when the rush current value exceeds 10A.
Please make sure to insert a protection resistor of about 1kΩ for charge and discharge when measuring the
leakage current.
4. Soldering
The soldering conditions must be kept within the permissible range prescribed in the catalog specification.
If the specification is not kept, there is the possibility of abnormal appearance and abnormal leakage current and reduced capacitance.
5. Installation on PC board
When designing the layout of your PC board using the FPCAP please take into consideration the standard mounting specifications.
The FPCAP can not be able to be mounted on a PC board if there is insufficient space.
6. Directions for use in circuits
Since leakage current fluctuations can occur during the soldering process the FPCAP cannot be used in the following circuits.
- High impedance voltage retention circuits
- Coupling circuits
- Time constant circuits
- Circuits greatly affected by leakage current
- Connecting two or more FPCAP in series
