Application Guidelines
1. Circuit Design: Considers effects of operating temperature and frequency on electrical parameters. Avoids reverse voltage, over voltage, excessive ripple current, and pulse current. Details on series/parallel capacitor usage, mounting considerations (double-sided boards, hole positioning, spacing, pressure relief vent clearance), electrical isolation, and capacitor sleeve properties are provided. Safety precautions for worst-case failure modes are emphasized.
2. Capacitor Handling Techniques: Includes considerations before use (finite life, transient recovery voltage, leakage current increase after storage, damage from dropping/denting). Details on insertion (polarity verification, hole spacing, auto insertion equipment stress). Manual and flow soldering guidelines, including temperature and time limits. Post-solder handling, circuit board cleaning procedures (solvent compatibility, drying), and mounting adhesives/coating agents are covered.
3. Precautions for using capacitors: Avoids storage or 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.
4. Emergency Procedures: Immediate equipment shutdown and power disconnection if pressure relief vent operates. Avoid contact with escaping electrolyte gas. First aid for eye/ingestion/skin contact with electrolyte.
5. Long Term Storage: Reconditioning by applying rated voltage in series with a 1000 resistor for 30 minutes is recommended after one year of storage. Products over eighteen months from date code require confirmation.
6. Capacitor Disposal: Recommended methods include incineration after crushing/puncturing or disposal as solid waste, following local laws. Incineration at high temperatures is advised to prevent toxic gas release.
