Usage Guidelines and Precautions

1. Polarity: DC electrolytic capacitors are polarized. Ensure correct polarity to prevent short circuits or damage. Use bipolar capacitors for uncertain or alternating polarity applications. Not suitable for AC applications.
2. Bipolar Capacitors: Suitable for pulsating and polarity-reversing circuits only. Not for pure AC or high ripple current circuits.
3. Operating Voltage: Do not exceed the rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life.
4. Ripple Current: Do not allow ripple current to exceed permissible limits. Excessive ripple current causes heat, reduced capacitance, and damage. Generally, do not exceed 80% of the rated current.
5. Charge/Discharge Circuits: For circuits with rapid charge/discharge cycles, use specially designed capacitors to prevent damage, capacitance decrease, and heat rise.
6. Operating Temperature: Capacitor characteristics vary with temperature. Lower temperatures ensure longer life.
7. Temperature vs. Life: Life is approximately doubled for every 10 decrease in temperature from the rated temperature. Formula provided for calculation.
8. Operating Frequency: Capacitance is typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies, leading to increased ambient temperature.
9. Storage: For capacitors stored long-term, apply rated DC voltage gradually before use. This addresses potential increases in leakage current and decreased withstand voltage.
10. Case Insulation: The capacitor case is not insulated from the cathode terminal. Implement insulation measures at the mounting point if case insulation is required.
11. Terminal/Lead Force: Do not apply excessive force to terminals or leads to prevent breakage, separation, or internal connection failure.
12. Bending Leads: When bending leads for horizontal mounting, maintain a 2mm safe distance from the capacitor body to avoid internal structural damage.
13. Circuit Board Cleaning: Do not use halogenated solvents (e.g., trichlorethylene, xylene, acetone) for cleaning. Recommended solvents include methanol, isopropanol, ethanol, isobutanol, petroleum ether, propanol, and general detergents.
14. Soldering: Keep soldering irons away from plastic sleeves. Recommended soldering temperature is within 260 for no more than 10 seconds to prevent damage.
15. Hole Layout: On printed circuit boards, mounting hole spacing should match lead spacing. Incorrect spacing can cause stress on leads, short circuits, or damage. Consider hole layout carefully to prevent solder splashing onto the capacitor body.
