Operating Precautions
- Polarity: Do not reverse polarity; it can lead to shortened life or short circuits.
- Prohibited Circuits: Avoid use in high impedance, coupling, time constant, or series connection circuits for higher withstand voltage without consulting the manufacturer.
- Over Voltage: Do not exceed the rated voltage, even momentarily.
- Sudden Charge/Discharge: Avoid sudden charge and discharge. Use protection circuits if rush current exceeds 10A or 10x allowable ripple current.
- Operating Temperature and Ripple Current: Exceeding temperature limits or ripple current can shorten life or cause failure.
- Leakage Current: May increase slightly after soldering but can self-repair with DC voltage.
- Applied Voltage: Recommended to operate at less than 80% of rated voltage. Peak DC and AC voltage should not exceed rated voltage.
Marking
Each unit or package will be marked with:
