Usage Precautions
Circuit Design: Use within rated performance, avoid high temperature, overcurrent, overvoltage, reverse voltage, rapid charge/discharge. Ensure proper isolation between terminals and casing. Select capacitors with a lifespan comparable to the machine's life. Discuss special requirements with R&D. Avoid environments with water, salt water, oil, or harmful gases. Protect from direct sunlight, ozone, UV, and radiation. Ensure vibration and shock conditions are within limits. Align capacitor polarity and board holes correctly. Ensure space above the safety vent and avoid placing components nearby. Avoid heat-generating components around the capacitor. For double-sided PCBs, avoid unnecessary holes. Balance current in parallel connections and voltage in series connections.
Component Installation: Do not let terminals touch. Avoid short circuits. Do not use capacitors that have been dropped or deformed. Ensure correct polarity. Do not use a dropped capacitor. Do not install deformed capacitors. Ensure hole spacing matches terminal spacing. Avoid excessive force with automatic insertion machines.
Soldering: Prevent solder from adhering to areas other than terminals. Follow specified temperature, time, and number of cycles. Do not immerse the capacitor body in solder. Avoid other products falling onto the capacitor during soldering.
Assembly Use: Do not let terminals directly contact each other. Prevent conductors from causing short circuits. Check the installation environment for water, oil, condensation, harmful gases, direct sunlight, ozone, UV, radiation, vibration, and shock. For stacked capacitors, ensure correct alignment and avoid interference.
Maintenance: Regular inspections (visual and performance testing) are required for industrial capacitors.
Accident Handling: If the safety vent opens, cut off the main power. Keep face away from venting gas (over 100). Flush eyes with water if gas enters. Do not taste electrolyte; wash skin with soap if contacted.
Fumigation Treatment: Be cautious with halide fumigation (e.g., potassium bromide) for overseas export, as it may cause corrosion. Fumigant should not directly contact products, and thorough drying is necessary.
Storage Conditions: Store indoors at 5-30 with humidity below 75%. Do not store in environments prohibited for use.
Disposal: Puncture or crush and incinerate, or hand over to specialized recycling personnel.
