Technical Specifications

Item	Description	Details
1. Polarity	DC Electrolytic Capacitors	Polarized; marked on the body. Use bipolar capacitors if polarity is uncertain. Not for AC application.
2. Bipolar Capacitors	Usage	Suitable for pulse and polarity reverse circuits; not for pure AC or high ripple current.
3. Voltage	Rated Voltage	Do not exceed rated voltage. Recommended working voltage is 70-80% of rated voltage for extended life.
4. Ripple Current	Permissible Limit	Do not allow ripple current to exceed permissible limits, generally not more than 80% of rated current, to prevent overheating and damage.
5. Charge/Discharge Circuits	Special Design	Use specially designed capacitors for circuits with frequent charge/discharge cycles to prevent damage and premature failure.
6. Operating Temperature	Range	Capacitor characteristics vary with temperature. Lower temperatures ensure longer life.
7. Temperature vs. Life	Relationship	Life is generally doubled for every 10 decrease in operating temperature from the rated temperature. Includes a formula for calculating life based on temperature and ripple current.
8. Operating Frequency	Measurement Basis	Capacitance typically measured at 100Hz or 120Hz. Capacitance decreases and tg increases with higher frequencies.
9. Long-Term Storage	Treatment Before Use	Apply rated DC voltage gradually before use to compensate for potential increases in leakage current and decreased withstand voltage.
10. Case Insulation	Cathode Connection	Capacitor case is not insulated from the cathode terminal. Insulation must be provided at the mounting point if required.
11. Terminal/Lead Force	Handling	Avoid applying excessive force to terminals and leads to prevent breakage or internal connection failure.
12. Bending Leads	Installation	Maintain a 2mm safe spacing between bent leads and the capacitor body to prevent internal structural damage.
13. Cleaning	Post-Soldering	Use recommended solvents (e.g., methanol, ethanol) and avoid halogenated solvents (e.g., trichlorethylene) to protect the capacitor body.
14. Soldering	Temperature & Duration	Keep soldering iron away from plastic sleeves. Recommended solder bath temperature:
15. PCB Hole Layout	Mounting Considerations	Hole spacing should match lead spacing. Careful consideration of hole layout is needed to prevent stress on leads and solder splashing onto the capacitor.
