Usage Precautions
Circuit Design: Use within rated performance, avoid high temperature, overcurrent, overvoltage, reverse/AC voltage, and rapid charge/discharge. Ensure isolation between capacitor terminals and circuit. Select capacitors with a lifespan comparable to the machine. Consider special requirements with R&D. Avoid contact with water, salt water, oil, or environments with harmful gases, direct sunlight, ozone, UV, or radiation. Ensure vibration and shock are within specified limits. Ensure correct polarity and spacing for PCB mounting. Avoid placing heat-generating components near capacitors. For multi-capacitor connections, ensure current/voltage balancing.
Component Installation: Do not allow terminals to short circuit. Do not use dropped or deformed capacitors. Ensure PCB hole spacing matches capacitor leads. Leave space above the safety vent. Avoid placing other components or wiring above the vent. Avoid other wiring near the capacitor on the PCB. Ensure the mechanical force of automatic insertion machines is not excessive.
Soldering: Prevent solder from adhering to areas other than terminals. Follow specified soldering temperature, time, and number of cycles. Do not immerse the capacitor body in solder. Avoid other products falling onto the capacitor during soldering.
Assembly Usage: Do not allow capacitor terminals to directly contact each other or cause short circuits. Confirm the installation environment is free from water, oil, condensation, harmful gases, direct sunlight, ozone, UV, radiation, excessive vibration, or shock.
Maintenance Check: Regular checks, including visual inspection and performance testing, are required for industrial capacitors.
Accidental Situations: If the safety vent opens during assembly, cut off power. Keep face away from vent due to high-temperature gas release. Flush eyes with water if gas enters, wash skin with soap if electrolyte contacts it, and do not ingest electrolyte.
Fumigation Treatment: Exercise caution with halide-based 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.
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.
