Application Guidelines
1. Circuit Design: Considers effects of operating temperature and frequency on electrical parameters. Avoids misapplication conditions like reverse voltage, over voltage, and excessive ripple current. Provides guidelines for series/parallel capacitor usage and mounting considerations including clearance for pressure relief vents and circuit board pattern design. Emphasizes electrical isolation and safety precautions.
2. Capacitor Handling Techniques: Includes considerations before use (finite life, transient recovery voltage, leakage current increase with storage, avoiding dropped or dented capacitors), insertion (verifying capacitance, voltage, polarity, hole spacing), soldering (manual and flow soldering specifications), and post-solder handling. Also covers circuit board cleaning and mounting adhesives.
3. Precautions for using capacitors: Advises against storing or using capacitors in extreme temperatures, direct contact with water/oil, high humidity, toxic gases, ozone, radiation, or excessive vibration/shock. Includes electrical precautions regarding terminal contact and short circuits.
4. Emergency Procedures: Outlines immediate actions if the pressure relief vent operates, including turning off equipment, avoiding contact with escaping electrolyte gas, and first aid measures for eye, mouth, or skin contact.
5. Long Term Storage: Notes that leakage current increases with long storage times and recommends reconditioning by applying rated voltage in series with a current limiting resistor. Products over eighteen months old should be returned for confirmation.
6. Capacitor Disposal: Recommends incineration after crushing or puncturing to prevent explosion, or disposal as solid waste, adhering to local laws.
