Application Guidelines

Provides guidance on circuit design, operating temperature and frequency effects, life expectancy, common application conditions to avoid (reverse voltage, charge/discharge, over voltage, ripple current), series/parallel capacitor usage, and capacitor mounting considerations. Also includes electrical isolation, product endurance, date code sampling, and capacitor sleeve information. Emphasizes safety precautions for worst-case failure modes.

Capacitor Handling Techniques

Details considerations before using (finite life, transient recovery voltage, leakage current increase with storage, avoiding dropped or dented capacitors), insertion procedures (verifying capacitance, voltage, polarity, hole spacing), manual and flow soldering guidelines, other soldering considerations, handling after solder, circuit board cleaning (acceptable solvents, drying, contamination monitoring), mounting adhesives, and coating agents.

Precautions for using capacitors

Outlines environmental conditions to avoid (temperature extremes, water, high humidity, toxic gases, ozone, radiation, vibration/shock) and electrical precautions (avoiding terminal contact, short circuits). Includes emergency procedures for vent operation and capacitor disposal methods.
