Application Guidelines

Circuit Design: Considerations for operating temperature, frequency effects on electrical parameters (leakage current, capacitance, ESR, impedance, tan), life expectancy, and common application conditions to avoid (reverse voltage, charge/discharge, over voltage, ripple current). Guidance on using capacitors in series or parallel, and mounting considerations including clearance for pressure relief vents.

Capacitor Handling Techniques: Considerations before use (finite life, transient recovery voltage, leakage current increase after storage, avoiding dropped or dented capacitors). Insertion procedures (verifying capacitance, voltage, polarity, hole spacing). Manual and flow soldering guidelines, including temperature and time limits. Post-soldering handling and circuit board cleaning recommendations, including acceptable solvents and drying procedures.

Precautions for Using Capacitors: Environmental conditions to avoid (temperature extremes, water, high humidity, toxic gases, radiation, vibration). Electrical precautions (avoid touching terminals, avoid short circuits). Emergency procedures for vent operation (turn off equipment, avoid contact with escaping electrolyte, first aid). Long-term storage recommendations including reconditioning procedures.

Capacitor Disposal: Methods include incineration after crushing or puncturing, or disposal as solid waste, following local laws.
