Usage Precautions
Circuit Design: Use within rated performance, avoid high temperature, overcurrent, overvoltage, reverse voltage, and rapid charge/discharge. Ensure proper isolation between capacitor terminals and other circuit components. Select capacitors with a lifespan compatible with the machine's expected life. Consider special requirements with R&D personnel.
Installation Environment: Avoid contact with water, saltwater, oil, or condensation. Do not use in environments with harmful gases (sulfides, etc.), direct sunlight, ozone, UV, or radiation. Ensure vibration and shock conditions do not exceed specified limits.
Assembly and Handling: Prevent direct contact between terminals and avoid short circuits. Ensure proper alignment with PCB holes. Leave space above the explosion-proof valve and avoid placing components nearby. Do not use dropped or deformed capacitors. Ensure correct polarity during installation. Avoid excessive force with automatic insertion machines.
Soldering: Prevent solder from adhering to areas other than terminals. Adhere to specified soldering conditions (temperature, time, cycles). Do not immerse the capacitor body in solder solution. Avoid other products falling onto the capacitor during soldering.
Cleaning: Do not use cleaning agents unless specified. If cleaning is necessary, follow product specifications regarding cleaning agents and drying procedures. Avoid halogen-containing fixatives or coating agents.
Storage: Store in a cool, dry indoor environment (5-30, <75% humidity), avoiding conditions prohibited during use.
Disposal: Dispose of by puncturing/crushing and incineration, or by handing over to specialized recycling personnel.
Accidental Situations: In case of explosion vent activation, disconnect power immediately. Avoid contact with ejected hot gas. Flush eyes with water if exposed, wash skin with soap if electrolyte contacts it. Do not ingest electrolyte.
Fumigation Treatment: Be cautious with halide fumigation (e.g., potassium bromide) for overseas export, as it may cause corrosion. Ensure fumigant does not directly contact products and allow for thorough drying.
