Application Guidelines

• Circuit Design: Considerations for operating temperature, frequency, reverse voltage, charge/discharge applications, over voltage, and ripple current.
• Series/Parallel Connection: Guidelines for using multiple capacitors in series or parallel to manage voltage and current imbalances.
• Mounting Considerations: Recommendations for circuit board design, hole positioning, spacing, clearance for pressure relief vents, wiring near vents, and screw terminal mounting.
• Electrical Isolation: Requirements for isolating the capacitor from other circuit paths and mounting terminals.
• Capacitor Handling: Precautions before use, insertion, manual soldering, flow soldering, and after soldering.
• Circuit Board Cleaning: Guidelines for cleaning solvents, temperatures, and drying procedures.
• Mounting Adhesives and Coating Agents: Avoidance of halogenated solvents and chloroprene based polymers.
• Environmental Conditions for Storage: Recommended temperature (5 to 35), humidity (less than 75%RH), and storage term (2 years).
• Electrical Precautions: Avoiding touching terminals, short circuiting, and understanding potential electric shock hazards.
• Emergency Procedures: Actions to take if the pressure relief vent operates, including immediate power off and first aid for electrolyte contact.
• Long Term Storage: Reconditioning procedures for capacitors stored for extended periods (over one year) to restore oxide film and prevent current surges.
