Technical Specifications

Usage Precautions

1. Circuit Design

• Ensure capacitors are used within their rated performance and environmental limits. Avoid high temperatures, overcurrent, overvoltage, reverse voltage, or frequent charge/discharge cycles.
• Select capacitors with a lifespan compatible with the machine's expected life.
• Isolate capacitor casing, terminals, and leads from positive/negative terminals and circuits.
• Do not use if the sleeve insulation is insufficient for specific requirements.
• Avoid environments with direct contact with water, saltwater, oil, condensation, or harmful gases (sulfides, etc.).
• Do not expose to direct sunlight, ozone, UV, or radioactive substances.
• Avoid environments with vibration and shock exceeding specified limits.
• Ensure proper spacing between capacitor terminals and PCB holes.
• Leave sufficient space above the capacitor's safety vent.
• Avoid placing wiring or other components directly above the safety vent.
• Minimize heat-generating components around the capacitor.
• Consider temperature and frequency variations affecting electrical performance.
• On double-sided PCBs, avoid mounting capacitors over unnecessary holes.
• Ensure current balance in parallel capacitor connections and voltage balance in series connections.

2. Component Installation

• Ensure capacitor terminals do not directly contact each other or other conductors, preventing short circuits.
• Check the environment at the installation location for water, oil, condensation, direct sunlight, ozone, UV, radiation, or harmful gases.
• Ensure vibration and shock do not exceed specified limits.

3. Assembly and Use

• Avoid direct contact between capacitor terminals. Prevent short circuits with conductive materials.
• Confirm the installation environment: avoid water/oil contact, condensation, direct sunlight, ozone, UV, radiation, or harmful gases.
• Avoid environments with excessive vibration and shock.

4. Regular Inspection

Factory and enterprise capacitors require regular inspections, including visual checks and performance testing.

5. Unexpected Situations

• If the capacitor's safety vent opens during assembly, disconnect the main power.
• When the safety vent activates, hot gas (>100) will be ejected. Avoid close proximity, and flush eyes immediately with water if gas enters. Do not ingest electrolyte; wash skin with soap if contacted.

6. Fumigation Treatment

When exporting products containing capacitors overseas, be cautious of corrosion caused by halogen-based fumigants (e.g., potassium bromide). Ensure fumigant does not directly contact products and allow for thorough drying. Consult safety data if fumigant residue is suspected.

7. Storage Conditions

• Store indoors at temperatures between 5-30 and humidity below 75%.
• Do not store in environments or conditions prohibited during assembly and use.

8. Disposal

• Dispose of by puncturing or crushing and incinerating.
• Alternatively, hand over to specialized waste recycling personnel if incineration is not feasible.
