Application Guidelines
Circuit Design: Electrical parameters vary with temperature and frequency. Designers should consider effects on leakage current, capacitance, and ESR. Avoid common misapplication conditions like reverse voltage, repeating charge/discharge, over-voltage, and excessive ripple current. For series/parallel capacitor use, consider voltage and current imbalances. Mounting considerations include avoiding wiring patterns under capacitors, matching hole spacing, providing clearance for pressure relief vents, and avoiding high voltage wiring near vents. Electrical isolation of the capacitor is crucial. Sleeve is for marking, not insulation.
Capacitor Handling: Do not reuse capacitors from used equipment. Discharge transient recovery voltage if necessary. Gradually apply rated voltage with a resistor for capacitors stored long periods. Avoid using dropped, dented, or crushed capacitors. Verify capacitance, voltage, and polarity before insertion. Ensure auto insertion equipment does not stress leads. Manual soldering should observe temperature and time specifications, avoiding stress on leads and contact with the capacitor body. Flow soldering requires adherence to conditions and avoiding immersion of the capacitor body. Avoid rapid temperature rises during preheat and resin bonding.
Post-Solder Handling & Cleaning: Avoid moving capacitors after soldering. Do not use capacitors as handles. Avoid striking capacitors after assembly. Circuit boards can be cleaned using suitable solvents, but avoid halogenated, alkali, petroleum-based, xylene, and acetone solvents unless specified. Thorough drying is required. Monitor cleaning solvent contamination levels. When using mounting adhesives or coating agents, avoid halogenated solvents and chloroprene based polymers.
Precautions: Do not store or use capacitors outside rated temperature ranges, in direct contact with water/oil, high humidity, toxic gases, ozone, radiation, or excessive vibration/shock. Avoid touching terminals due to potential electric shock. 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 if ingested, and wash skin with soap and water if contacted.
Long Term Storage: Leakage current increases with storage time. Recondition capacitors after one year by applying rated voltage in series with a 1000 resistor for 30 minutes. Products over eighteen months past their date code require confirmation. Environmental conditions for storage are critical.
Capacitor Disposal: Incinerate after crushing or puncturing the can wall, or dispose of as solid waste, following local laws. Incineration at high temperatures is recommended to prevent toxic gas release.
