Usage Precautions
- Electrolytic capacitors are polarized; ensure correct polarity to prevent short circuits or damage. Use non-polarized capacitors if polarity is uncertain or may be reversed.
- Do not apply reverse voltage or DC voltage exceeding the rated voltage. Exceeding rated voltage significantly increases leakage current and can cause damage. Use at rated voltage for optimal lifespan. Surge voltage is the maximum voltage the capacitor can withstand for short periods.
- Ripple current should be less than the rated value. Exceeding ripple current limits causes overheating, capacitance drop, and reduced lifespan. The peak ripple voltage plus DC voltage should not exceed the rated working voltage.
- Operate within the rated temperature range. Exceeding the upper limit drastically shortens lifespan or activates the safety vent. Operation at room temperature ensures a longer lifespan. For every 10C decrease in ambient temperature, lifespan doubles.
- Long-term storage can increase leakage current, especially at higher temperatures. Store in a suitable environment. Applying voltage will decrease leakage current. If high leakage current affects the circuit, pre-charge the capacitor before use.
- Not suitable for circuits with frequent charge/discharge cycles. Capacitance may decrease due to negative electrode oxidation, or damage may occur from heat generated during charge/discharge.
- Improper installation or stress on leads can damage internal structure, leading to high leakage current or leakage. Ensure good soldering, correct PCB hole spacing, do not bend leads excessively, and avoid bending/twisting the capacitor body when soldering.
- During tin dipping or soldering, the sleeve may crack or shrink due to excessive time or temperature.
- Do not use halogenated organic solvents for cleaning. If cleaning is necessary, use a cleaner that guarantees capacitor quality. After cleaning, do not store in the cleaning solution or sealed containers. Dry with hot air (not exceeding the upper temperature limit) for over 10 minutes.
- Do not use halogenated organic fixing agents or coatings. Do not seal the capacitor's entire sealing area with fixing agents or coatings.
- Recommended storage: ~35, <75% RH, out of direct sunlight. Shelf life is 12 months from ex-factory date. Check electrical characteristics and solderability if stored beyond 12 months.
- Dispose of waste capacitors through local industrial waste disposal services.
- Refer to EIAJ RCR-2367B for more details.
