Environment-related Substances

Refers to the latest document of Environment-related Substances standard (WI-HSPM-QA-072). Lists controlled substances including heavy metals, chlorinated organic compounds, brominated organic compounds, etc.

Attachment: Application Guidelines

Provides guidance on circuit design, operating temperature and frequency effects, common application conditions to avoid (reverse voltage, over voltage, ripple current), series/parallel capacitor usage, and capacitor mounting considerations (circuit board layout, hole spacing, clearance for vents, wiring near vents).

Capacitor Handling Techniques

Includes considerations before using (finite life, transient recovery voltage, leakage current increase with storage, impact of dropping/denting), insertion procedures (polarity, hole spacing, lead clinching), manual and flow soldering guidelines, other soldering considerations, post-solder handling, circuit board cleaning recommendations (solvents, drying, contamination monitoring), and mounting adhesives/coating agents.

Precautions for Using Capacitors

Details environmental conditions to avoid (temperature extremes, water contact, high humidity, toxic gases, radiation, vibration/shock) and electrical precautions (electric shock risk, short circuiting).

Emergency Procedures

Instructions for immediate actions if the pressure relief vent operates (turn off equipment, disconnect power) and first aid for contact with electrolyte or gas.

Long Term Storage

Addresses increased leakage current with long storage times and the need for reconditioning by applying rated voltage through a current-limiting resistor.

Capacitor Disposal

Recommends incineration after crushing or puncturing, or disposal as solid waste, adhering to local laws.
