When using aluminum electrolytic capacitors, strictly observe the following precautions:

1. Electrolytic capacitors for DC applications require polarization. Confirm polarity before use. Reverse polarity may shorten circuit life or damage the capacitor. For circuits with occasional polarity reversal or unknown polarity, use bipolar capacitors (BP series). Note that electrolytic capacitors cannot be used in AC applications.
2. Do not apply voltage exceeding the capacitor's rated voltage. Exceeding the rated voltage will increase leakage current and may damage the capacitor. When superimposing AC voltage on DC voltage, ensure that the peak AC voltage does not exceed the rated voltage.
3. Do not allow excessive ripple current. Operate the electrolytic capacitor within the specified ripple current rating. If ripple current exceeds the specified value, request capacitors suitable for high-ripple-current applications.
4. Observe the operating temperature range. Use electrolytic capacitors within the specified operating temperature range. Operating at room temperature ensures longer service life.
5. Electrolytic capacitors are not suitable for circuits with frequent charge/discharge cycles. Use in such circuits may cause capacitance drop or capacitor damage. Consult our engineering department for assistance with these applications.
6. Perform voltage conditioning on electrolytic capacitors that have been stored for an extended period. Long-term storage may reduce the withstand voltage, leading to increased leakage current. Applying rated voltage to such capacitors generates excessive leakage current and internal heat, potentially causing damage. Therefore, perform voltage conditioning before use after extended storage (Note 1). (However, if the capacitor has been stored at room temperature for less than two to three years, voltage conditioning is not required.)
7. Control temperature and time during soldering. When soldering PCBs with various components, ensure that the soldering temperature is not excessive and the dipping time is not too long. Otherwise, the electrical characteristics and insulating sleeve of the electrolytic capacitor may be adversely affected. For small electrolytic capacitors, no abnormality will occur if dipping is performed at temperatures below 260℃ for less than 10 seconds.
8. Do not contact the capacitor body with a soldering iron. Electrolytic capacitors are covered with a vinyl sleeve. Contact between a soldering iron and the capacitor body during wiring may damage the vinyl sleeve and/or case, resulting in poor insulation or inadequate protection of the capacitor element.
9. Clean the PCB after soldering. Some solvents have adverse effects on capacitors. Refer to the following page for details.
10. Do not apply excessive force to leads or terminals. Excessive force on leads and terminals may cause them to break or impair their connection to internal elements. (For terminal strength, refer to KS C IEC 60384-4 (JIS C5101-1, JIS C5101-4).)
11. Exercise caution in selecting storage areas. Exposure to high-temperature environments such as direct sunlight may adversely affect capacitor life. Storage in high-humidity environments may affect the solderability of leads and terminals.
12. Surge voltage. The surge voltage rating is the maximum DC overvoltage a capacitor may withstand for short durations not exceeding approximately 30 seconds at infrequent intervals not exceeding six minutes. Per KS C IEC 60384-4, capacitors with characteristics conforming to KS C IEC 60384-4 shall be tested for 1000 cycles at room temperature; KS C IEC 60384-4 capacitors with characteristics B and C shall be tested at maximum operating temperature by applying voltage through a 1000-ohm series resistor without discharge. The electrical characteristics of capacitors after testing are specified in KS C IEC 60384-4. Unless otherwise specified, the rated surge voltage is as follows: Note 1: Voltage conditioning — Voltage conditioning shall be performed by gradually increasing the voltage to the rated voltage of the capacitor while reducing the leakage current. The applied voltage shall remain within the range where the leakage current of the electrolytic capacitor is below the specified value. Additionally, increasing the ambient temperature (within the operating temperature range) can effectively reduce the voltage conditioning time. Note 2: For test methods, refer to KS C IEC 60384-4 (JIS C 5101-1, JIS C 5101-4).
