Application Guidelines
Circuit Design: Electrical parameters vary with temperature and frequency. Consider effects on leakage current, capacitance, and ESR. Avoid reverse voltage, over voltage, and exceeding ripple current limits. Use appropriate capacitors for charge/discharge applications. When using multiple capacitors in series or parallel, consider voltage and current balancing. Ensure proper mounting to avoid short circuits, lead stress, and vent obstruction. Provide adequate clearance for pressure relief vents. Electrical isolation of the capacitor is required.
Capacitor Handling: Do not reuse capacitors from used equipment. Discharge transient recovery voltage if necessary. Recondition capacitors stored for long periods by applying rated voltage through a current-limiting resistor. Avoid using dropped, dented, or crushed capacitors. Verify capacitance, rated voltage, and polarity before insertion. Ensure auto insertion equipment does not stress leads. Observe soldering temperature and time specifications. Avoid stress on lead wires. Do not immerse capacitor body into solder bath. Avoid rapid temperature rises during preheating. Avoid movement of the capacitor after soldering. Do not use capacitor as a handle. Avoid striking the capacitor. Clean circuit boards using suitable solvents, avoiding halogenated, alkali, petroleum-based, xylene, and acetone solvents unless specified. Ensure thorough drying after cleaning. Monitor contamination levels of cleaning solvents. Avoid mounting adhesives or coating agents containing halogenated solvents or chloroprene based polymers.
Precautions for using capacitors: Do not store or use in extreme temperatures, direct contact with water/oil, high humidity, toxic gases, ozone, radiation, or excessive vibration/shock. Avoid touching terminals due to electric shock risk. Do not short circuit terminals with conductive materials.
Emergency Procedures: If the pressure relief vent operates, immediately turn off equipment. Avoid contact with escaping electrolyte gas. Flush eyes with water if electrolyte enters. Gargle with water if ingested. Wash skin with soap and water if electrolyte contacts skin.
Long Term Storage: Leakage current increases with long storage. Recondition capacitors stored for over one year by applying rated voltage in series with a 1000 resistor for 30 minutes. Products over eighteen months old require confirmation.
Capacitor Disposal: Incinerate after crushing or puncturing to prevent explosion. Dispose of as solid waste, following local laws.
