Application Guidelines

Circuit Design: Considers effects of operating temperature and frequency on electrical parameters. Avoids reverse voltage, repeating charge/discharge applications, over-voltage, and excessive ripple currents. Guidelines for series/parallel capacitor usage and mounting considerations (e.g., board layout, hole spacing, pressure relief vent clearance). Electrical isolation requirements are detailed.

Capacitor Handling: Includes considerations before use (finite life, transient recovery voltage, leakage current increase with storage, damage from dropping/denting). Detailed insertion, manual soldering, flow soldering, and other soldering considerations. Post-solder handling, circuit board cleaning, and mounting adhesives/coating agents are discussed.

Precautions for Using Capacitors: Advises against storage/use in extreme temperatures, direct contact with water/oil, high humidity, toxic gases, ozone/radiation, and excessive vibration/shock. Electrical precautions include avoiding terminal contact and short circuits.

Emergency Procedures: Instructions for handling pressure relief vent operation and contact with escaping electrolyte/gas.

Long Term Storage: Reconditioning procedure for capacitors stored for over one year or eighteen months is outlined.

Capacitor Disposal: Recommended methods include incineration after crushing/puncturing or disposal as solid waste, adhering to local laws.
