Usage Precautions

Circuit Design:

• Use within rated performance limits, avoid high temperatures, overcurrent, overvoltage, reverse voltage, AC voltage, and rapid charge/discharge cycles.
• Select capacitors with a lifespan comparable to the machine's.
• Ensure complete isolation between capacitor terminals, casing, and circuit.
• Avoid using if casing insulation is insufficient.
• Do not use in environments with direct contact with water, saltwater, oil, condensation, harmful gases, sunlight, ozone, UV radiation, radioactive substances, or excessive vibration/shock.

Installation:

• Ensure correct polarity and matching hole spacing.
• Leave space above the safety vent.
• Avoid placing other components or wiring above the vent.
• Avoid placing other wiring near the capacitor on the PCB.
• Minimize heat-generating components around the capacitor.
• On double-sided PCBs, avoid unnecessary substrate holes and via holes near the capacitor.
• Ensure current equalization for parallel connections and voltage equalization for series connections.

Assembly & Soldering:

• Prevent direct contact between terminals and short circuits.
• Avoid exposure to water, oil, condensation, sunlight, ozone, UV, radiation, or harmful gases.
• Do not exceed specified vibration and shock limits.
• Do not use dropped capacitors.
• Do not install deformed capacitors.
• Ensure proper soldering temperature, time, and number of times as per specifications.
• Avoid solder adhering to areas other than terminals.
• Do not immerse the capacitor body in solder solution.
• Prevent other products from falling and hitting the capacitor during soldering.
• Do not use capacitors that have been removed from the machine for inspection or testing.
• Discharge capacitors with regenerative voltage using a ~1K resistor.
• Discharge long-term stored capacitors using a ~1K resistor.

Cleaning:

• Avoid using cleaning agents. If necessary, clean within product specification limits.
• Ensure proper cleaning agent management (conductivity, pH, specific gravity, moisture).
• After cleaning, do not store in cleaning liquid or sealed containers. Dry with hot air below the maximum operating temperature.

Fixing Agents & Coatings:

• Do not use halogen-containing fixing agents or resin coatings.
• Ensure no solder residue or dirt remains between the PCB and capacitor.
• Dry thoroughly before applying fixing agents/coatings to prevent clogging.

Bolt Type Installation:

• For vertical installation, pressure valve must face upwards.
• For horizontal installation, ensure the pressure valve or positive terminal faces upwards.

Maintenance & Disposal:

• Regular inspections (visual and performance testing) are required for industrial capacitors.
• In case of vent opening, cut off main power.
• Keep face away from vent during operation; flush eyes with water if exposed to ejected gas. Wash skin with soap if electrolyte spills.
• For overseas export, be cautious with fumigation (e.g., potassium bromide) due to potential corrosion. Ensure fumigant does not directly contact products and allow for thorough drying.
• Store in a cool, dry indoor environment (5-30, <75% humidity).
• Do not store in prohibited environments.
• Dispose of waste capacitors by puncturing/crushing and incineration, or by handing over to professional recyclers.
