Important Usage Notes
- Electrolytic capacitors require polarization. Reversed polarity can shorten life or damage the capacitor. Use bi-polarized capacitors for circuits with occasional or unknown polarity. Not suitable for AC applications.
- Do not exceed the rated voltage. Peak voltage of AC superimposed on DC must not exceed the rated voltage.
- Operate within permissible ripple current range. Request high ripple current capacitors if needed.
- Use within the specified operating temperature range for optimal life.
- Not suitable for circuits with frequent charge/discharge cycles. Consult engineering for assistance.
- Apply voltage treatment to capacitors stored for extended periods (over 2-3 years at normal temperature) to prevent increased leakage current and potential damage.
- Be careful of temperature and time when soldering (e.g., <260 for <10 seconds for small-sized capacitors).
- Do not place a soldering iron on the capacitor body to avoid damaging the vinyl sleeve.
