Application Guidelines

• Circuit Design: Considerations for operating temperature and frequency effects on electrical parameters. Avoidance of common misapplication load conditions like reverse voltage, charge/discharge applications, over voltage, excessive ripple current, and pulse current. Guidelines for using capacitors in series or parallel.
• Capacitor Mounting Considerations: Double-sided circuit boards, circuit board hole positioning and spacing, clearance for pressure relief vents, wiring near vents, circuit board patterns under capacitors, and screw terminal mounting.
• Electrical Isolation: Requirements for isolating cathode from case, anode terminal from other paths, and extra mounting terminals.
• Capacitor Handling Techniques: Considerations before use (finite life, transient recovery voltage, leakage current increase after storage, mechanical damage). Insertion guidelines (polarity, hole spacing, lead clinching). Manual and flow soldering procedures. Handling after solder.
• Circuit Board Cleaning: Acceptable cleaning methods, solvents, drying procedures, and contamination monitoring.
• Mounting Adhesives and Coating Agents: Precautions regarding solvent content and drying.
• Precautions for using capacitors: Environmental conditions to avoid (temperature extremes, water contact, high humidity, toxic gases, radiation, vibration/shock). Electrical precautions (electric shock risk, short circuiting).
• Emergency Procedures: Actions to take if the pressure relief vent operates. First aid for electrolyte contact.
• Long Term Storage: Reconditioning procedures for capacitors stored for extended periods.
• Capacitor Disposal: Recommended methods including incineration after crushing/puncturing or disposal as solid waste, adhering to local laws.
