Application Guidelines

These capacitors are intended for use in electronic equipment. Designers should consider the effects of operating temperature and frequency on electrical parameters. Avoid common misapplication conditions such as reverse voltage, repeating charge/discharge, over-voltage, and excessive ripple current. Proper handling, insertion, and soldering techniques are crucial to prevent damage and ensure performance. Ensure adequate clearance for pressure relief vents and avoid wiring near them. Electrical isolation between cathode and case, and anode terminal and other circuit paths is required.

Capacitor Handling Techniques

Handle capacitors with care to avoid mechanical or electrical damage. Verify correct polarity and voltage rating before insertion. Observe specified soldering temperatures and times. Avoid stressing lead wires during insertion or soldering. Clean circuit boards using suitable solvents and ensure thorough drying. Avoid using halogenated, alkali, petroleum-based solvents, xylene, or acetone unless specified. When using mounting adhesives or coating agents, ensure they are free of halogenated solvents and chloroprene-based polymers.

Precautions for Using Capacitors

Do not store or use capacitors outside their rated temperature range. Avoid direct contact with water, salt water, oil, or toxic gases. Protect from vibration and shock exceeding specified requirements. Avoid touching terminals to prevent electric shock. Do not short circuit terminals with conductive materials. In case of pressure relief vent operation, immediately turn off equipment. Avoid contact with escaping electrolyte gas. Follow first aid procedures if electrolyte contacts skin, eyes, or is ingested.

Long Term Storage

Leakage current may increase with long storage times. Recondition capacitors stored for over one year by applying rated voltage in series with a 1000 current limiting resistor for 30 minutes. Products with date codes over eighteen months should be returned for confirmation. Environmental conditions for storage and use are critical; avoid extreme temperatures, moisture, corrosive gases, radiation, vibration, and shock.

Capacitor Disposal

Dispose of capacitors by incineration after crushing or puncturing to prevent explosion, or dispose of as solid waste, following local regulations. Incinerate at high temperatures to prevent release of toxic gases.
